American cone seating. What is "American" in plumbing: types and options for fittings

In plumbing work, it is often necessary to join various pipes together. To accomplish this, many fittings have been invented, the most famous of which is the squeegee. But this connecting element has significant drawbacks and high labor intensity in the performance of work. The “American” will be a more convenient and faster connection element, since its qualities will fully ensure a reliable tight connection.

What is an "American" in plumbing: design and characteristics

"American" in plumbing, the correct name of which is a union nut, is a connection element for various pipelines with internal and external threads. With the help of such an element, pipe joining is quick and convenient. Structurally, the "American" has the following elements:

Quick release hex nut with thread;

Two fittings, also threaded;

Paronite, rubber or polyurethane gasket (some models, such as cone, are not equipped with it).

To put it simply, the “American” is a coupling with a shoulder and a union nut that abuts against the shoulder. Thus, the plumbing "American" provides a coupling connection of pipes by rotating one nut. In a similar way, the connection is disassembled.

"American" in plumbing is designed for operating temperatures up to +120 degrees Celsius, and the maximum pressure is usually indicated on the body.

The surface of the "American" is covered with nickel, which prevents corrosion and damage, and also improves the appearance of the product. If you work with this fitting carelessly and with a rough tool, then its surface may become scratched.

Why do we need an "American" in plumbing: the main areas of application

Since the "American" is a fairly versatile fitting that has a number of undeniable advantages, it is not by chance that its use in plumbing has become the most widespread in plumbing installation work. The versatility of the "American" is manifested in its unequal modifications for different cases, and in the fact that it is used as part of some complex plumbing devices: taps, switching units, measuring instruments, etc.

In household plumbing, "American" is used on water meters, which are found in almost every apartment. Thanks to this device, when replacing or checking the meter, there are no problems with pipes - only union nuts are unscrewed.

"American" is perfect for working with batteries, valves and all kinds of filters. The use of this fitting in plumbing will shorten the duration of the repair, which is important for both craftsmen and residents.

Since the "American" allows you to create connections that are distinguished by excellent sealing, it is used in high pressure and temperature pipelines. But this connection element was most widely used during the installation of plastic, polypropylene and metal-plastic pipes. At the same time, any type of pipe can be connected: plastic and plastic, plastic and metal, metal and metal - there is a fitting for each pair. Most of all in the "American" plumbers appreciate the ability to connect metal-plastic pipes without any preparation: when the pipe is inserted into the union nut and tightened, the counterpart is compressed by a conical ring.

For the installation of the "American" use open-end and box wrenches. Since the surface of this fitting is covered with nickel, it is better not to use pipe wrenches or use a protective wooden (or plastic) gasket to protect this layer from scratches.

"American": the benefits of the connection

Compactness, which the clutch with a clutch cannot boast of.

Versatility. Using different types, it is possible to mount connections with internal and external threads, as well as elbow and straight connections for pipes of different diameters.

Installation speed. In fact, the connection is made by tightening the nut.

Possibility of reuse. "American" in plumbing can be dismantled and re-installed on another section of the pipeline. In this case, only the gasket changes (if any).

Ease of installation in hard-to-reach places.

High degree of reliability and sealing.

The ability to quickly eliminate the blockage in the pipe.

When using a conical connection using an "American" on a pair of metal pipes, the use of a gasket is not required. In this way, the service life of the pipes is increased.

What are the types of "American women" (plumbing)

"Americans" in plumbing are represented on the market by a fairly extensive range. They differ from each other in material, size, type of thread and fastening. For each type of pipeline, its own specific "American" is suitable.

Types of fasteners connection "American"

Tapered

The conical connection of the fittings provides maximum tightness without the need for a gasket. Also, such joints are immune to temperature fluctuations in the pipe. Another plus of such a connection is the preservation of tightness when the axes of the pipes deviate, if the angle does not exceed 5 degrees. The conical connection is best suited for installing a thermostat on a heating radiator. Since the taper joint does not contain a gasket, the regulator will be more resistant to leakage during temperature changes.

Cylindrical (flat)

This is the most common type of "American" in plumbing. This type is used in most pipelines. In the specified connection, the tightness is ensured by the union nut that creates the screed and the gasket.

Sometimes flat washers are found on some plumbing fixtures. In this case, the connection will be less reliable, there is a possibility of its depressurization. Therefore, it is better to mount the connection with flat washers in an accessible place, not to remove it into the walls.

There are also two types of threaded connection "American"

direct. Suitable for mounting straight pipes

Angular. It is used when joining two pipes at a right angle. Connects perpendicular pipes.

Depending on the size there are "American" 1 inch, ½ inch and ¾ inch.

Features of an American crane

Ball valve with proper workmanship is the most popular and best type of valves. There are many such taps on the sanitary ware market: special taps, with threads inside and outside both on one and both sides, decorative taps, an American ball valve, etc.

Despite the fact that the “American” faucet is not uncommon, it does not find wide application in plumbing work. This comes from ignorance of all the advantages of this type of faucet, the main of which is the ability to install plumbing without the use of a plumbing fixture, which includes a long thread, a coupling, a lock nut and a reciprocal thread. Thus, using the “American” crane, we, only by rotating the wrench, get the docking of two self-centering parts. Everything is simple.

Also, the “American” ball valve is used when installing heating radiators. The radiator, docked on both sides through an “American” crane, can be easily removed. It is also very easy to manually adjust the flow of coolant on it, and therefore regulate the heating of the radiator itself.

Attention deserves the corner crane-"American". It has been on sale more and more lately. Such a device easily replaces in some cases an excessive number of connections.

The “American” crane, like other cranes, has two types of handles - a lever and a butterfly. The butterfly is installed on small cross-section cranes, where it does not require much effort to turn. The lever, on the contrary, is mounted on a crane with a large section, where it is necessary to apply more force to turn.

What materials is the "American" made of?

Americans are made from the following materials:

• Brass ("American" from this material is chosen by specialists, since brass keeps the temperature of the coolant up to 120 degrees; in brass "American" some parts can be made of nickel or chromium);

  Stainless steel grades ISI304, AISI316, AISI321 (marking contains information about the size in inches, steel grade and conditional pressure);

  Combined, using propylene parts.

Also in plumbing there are "American women", differing in diameter and performance in general. They are used in systems with hot and cold water supply. Corner "American" in plumbing is necessary for the installation of various elements in hard-to-reach places.

Of the above materials, "American" stainless steel has the highest strength. However, most plumbers choose "American" chrome, as this material provides more practicality and quality. Also, elements made of this metal do not require gaskets to ensure tightness.

How is the "American" installed

In plumbing, the “American” connection (threaded) is mounted extremely simply. "American" will allow you to install or replace a plumbing element, even for a novice plumber or a simple layman.

The most suitable place for pipe installation is one where there is access for any person carrying out this work. In this case, the direction of the coolant does not matter.

Installation of "American" (plumbing) in the highway will not cause much trouble. Imagine that you need to join steel pipes.

The connection using the "American" takes place in the following order.

It is necessary to prepare the ends of the pipes - cut at least 7 turns of thread.

Select connection with fittings with female thread.

Screw a fitting with an external thread onto one of the pipes, the threads of which are lined with flax, tow or energy flex.

Put the union nut on the collared fitting, then screw it onto another pipe with applied winding.

Connect the union nut to the thread of the mating fitting.

After these steps, the structure will be assembled. Compared with the coupling connection, the installation of the "American" in plumbing consisted only in twisting the parts. The rest of the highway remained motionless.

An "American" with an external thread is mounted according to the same algorithm, with the exception that the winding is applied to the "American" thread.

What is the key for the "American"

You can mount the "American" in plumbing without losing quality and convenience with different tools. But it cannot be said that there are no restrictions in their choice. The most suitable and often used for mounting the "American" is an adjustable wrench.

For the installation of this fitting in plumbing, the use of gas wrenches should be avoided in every possible way.

Recently, a universal tool has appeared that is most suitable for installing pipes in plumbing, including for the "American". This wrench is used for a wide variety of jobs, which clearly proves its convenience and practicality.

The most common sizes of "American" in plumbing are ¾ inch and ½ inch. This generally does not mean that you will not need other types of this fitting. In this case, you must purchase a wrench of a suitable size or use an adjustable wrench. The main thing is not to use a gas key under any circumstances.

If you know how to work with metal and have the necessary tools, then you yourself can make a cone wrench of the desired size. The taper is needed to get into the recesses.

The shape of the key will be L-shaped, the handle is about 150 mm long. The key sizes for the "American" in plumbing ½ inch will be 12x12 mm and 10x10 mm. As a rule, such keys are made from profile fittings.

A good alternative when working with a plumber with an "American" ½ inch will be pliers, which, as a rule, everyone has. They will perfectly replace a set of keys.

"American" in plumbing: price and where to buy

The price of "American women" is not exorbitant, so everyone can afford to purchase them for their plumbing needs. The use of these fittings in water supply systems of both residential and industrial buildings also indicates their availability.

The company "SantekhStandard" has been successfully operating in the plumbing market in Russia since 2004. The profile of work is large-scale wholesale deliveries of engineering systems for heating and water supply under our own brands AQUAPIPE, AQUALINK, AQUALINE.

The company's products are manufactured using high-tech equipment and meet high international quality standards. The production has a system of input control of raw materials and components, as well as a quality control system at all production stages. Thus, the product fully complies with the declared characteristics.

The company "SantekhStandart" presented in its catalog "American" and "American" taps for the following brands.

AQUAPIPE. Propylene fittings from this manufacturer are manufactured using modern production equipment from raw materials Borealis (Germany), which guarantees their highest quality. Unlike other well-known brands, AQUAPIPE has a wide range of "American" (sanitary ware) made of polypropylene, as well as other polypropylene products, the range of which is regularly updated with new models.

AQUALINK. Threaded fittings of this manufacturer are represented by a large number of models of different types and sizes. The body of these fittings is made of brass brand CW617N, which is a complete analogue of domestic brass LS59 GOST 15527-2004. In the manufacture of the case, the method of hot pressing is used, which reduces the internal stress of the metal, thereby significantly increasing the strength and quality of the product.

LEXLINE. Under this brand, brass threaded fittings and pipe fittings for plumbing of the highest quality are produced. Production is located in Ukraine. The variety of these products is also great: fittings for gas and water pipes (including with a seal), suitable for plumbing, heating and gas pipeline systems in which there is a non-aggressive medium - water, steam, air, combustible gas. The connecting parts are made of brass brand LS-59-1 GOST 17711.

All questions regarding the connection using the "American", you will be answered by phone:

Plumbing assembly is considered to be of high quality if all connections are sufficiently tight. In practice, this is achieved through the use of various fittings, nuts, gaskets and other connecting elements used in plumbing work. Such elements are quite suitable for effective use, but at the same time there is a much better solution in the form of a universal nut, known as the "American".

Let's figure out what "American" is and why it has gained such great popularity.

The American plug connection is a kind of nut that finds its application when it becomes necessary to connect two pipes. Previously, spurs were used for this, which are still found today, since their cost is significantly lower compared to the connection of the type in question.

The use of "American women" in plumbing makes it possible to simplify the process of connecting two fixed pipes as much as possible. For example, you need to connect a faucet and soldered wiring. Both in the first and in the second case, the pipes cannot be twisted, and, possibly, the thread is located close to the wall, which excludes the use of the same corner. It is in such situations that the "American" comes to the rescue, providing a connection due to the rotation of the nut, which is part of its design:

• two fittings;
• pad;
• hex nut.

Pipe connection options

The connection of the "American" type is provided due to a certain variability of the connection to the pipe, which involves the use of:

Types of threaded connections

The thread of the "American" can be conical or cylindrical. A similar variability is present in the case of fittings, the connecting surfaces of which differ in the mentioned shapes.

As for the conical seal, it has a certain set of advantages:

• ensuring the tightness of the connection without any gaskets, FUM tape, flax fiber, etc.;
• resistance to various kinds of influences, for example, temperature extremes, which is achieved due to the homogeneity of the material in terms of its chemical composition and physical characteristics;
• preservation of tightness with deviations of the axes of the connected parts up to 5 degrees.

The mentioned advantages in relation to the conical elements of the "American" are achieved due to the high precision of their manufacture, which can be neglected to a certain extent when it comes to flat seals. Here, the use of a gasket in the form of a ring is sufficient to achieve the required tightness even when the surface of the connecting elements is not distinguished by high-precision processing.

In the production of "American women" steel of various grades is used. Although AISI steel under the numerical designations 304, 316 and 321 is more popular. Steel marking also includes an indication of nominal pressure (PSI) and size in inches.

Gusset

For the convenience of organizing turns, an "American" is produced, providing a corner connection. Usually this is in demand when there is no possibility of arranging piping. At the same time, it is possible to save money, since in this case one less connection is established.

Coupling

A coupling is a fitting that provides a connection between pipes or makes it possible to organize a transition from a pipe of one diameter to a pipe of another diameter. The “American” is identical in functionality to a standard coupling, one part of which is screwed, soldered or welded to the pipe, and the other provides for the installation of a collapsible connection.

Crane "American"

Ball valves are the most popular elements of shut-off valves, of course, provided that they are manufactured in accordance with the required level of quality. There is a huge mass of these products, among which there are taps oriented, for example, to some special use or performing decorative functions. At the same time, there is also an “American”, supplemented by a ball valve.

Many people know that this type of crane exists, but only a few have used it in practice. This state of affairs is due to simple ignorance of all the advantages of this product. Meanwhile, with its help, you can replace such an element of plumbing as a squeegee - a part for connecting two pipes, where a long thread is applied on one side, and a short one on the other, which is complemented by a coupling and a lock nut. In the proposed version, everything is much simpler, since it provides for the contraction of the crane and the element in the form of the “American” itself due to the slight use of the wrench. These two parts are self-centering, which facilitates the process of their installation.

Often, the "American" faucet is used when installing heating radiators, which leads to some positive aspects. The connection of these connecting elements makes it easy to dismantle the radiator, and the presence of a tap makes it possible to regulate the water supply, which allows you to influence the temperature in the room.

Like all types of ball valves, the "American" is equipped with two types of handles, where one should be understood as a butterfly, and under the other - a lever. In the first case, these are cranes with a small section, characterized by the absence of the need to apply too much force to turn, and in the second case, cranes with a large section, the operation of which is associated with the application of a greater force.

Assembly

The “Americana” union nut is tightened with a standard open-end wrench or a union version of this type of tool is used. Some try to use a spanner, which is not recommended as it may damage the nickel plating. If there is a decorative coating on the nut, rubber or plastic gaskets should be used, and plywood can also be used.

The installation of "American women" on metal-plastic pipes involves the use of a special tool in the form of an internal key. It is necessary for tightening the press fitting during installation. Typically, such a key is in the form of a cylinder, complemented by two recesses that are necessary for the hooks, but a hexagonal version is also available.

Instead of an internal key, an improvised tool, such as pliers, is often used, which increases the likelihood of damaging the product in question. When one-time work of this plan is supposed, that is, it is necessary to install only one connection of the "American" type, then this approach is justified to a certain extent, but in the case of installing several pipes, you should still take care of buying a special tool.

If you have the skills to work with metal, then you can easily make your own cone wrench of the required size. Tapering is necessary to ensure that it enters the existing recesses. Profile fittings can be used as a material for making a key.

For the "American", the diameters of the internal and external threads of which are defined as 1/2, a key is required in accordance with such dimensions as 12 by 12 mm and 10 by 10 mm. The shape of the key should resemble the letter "G", having a handle length of 150 mm.

Materials for the manufacture of "American"

The production process of "American women" is based on the following types of materials:

• cast iron;
• nickel;
• chromium;
• brass, chosen due to the fact that this material is able to withstand high temperatures of the coolant, reaching 120 ° C;
• stainless steel (ISI304, AISI316, AISI321) ;
• combined, including propylene.

Of the above materials, stainless steel is worth mentioning again, as it provides the ability to produce the most durable "American". Although consumers of these products often prefer copies made of chrome, as this material combines quality and practicality. It also does not require the installation of a gasket for "American" chrome to ensure the tightness of the connection.

If pure steel is used for the production of the type of product in question without special treatment, then after a few years such a product will begin to collapse. Galvanized can withstand about 10 years, and stainless - about 20 years.

Conical or flat?

Conical "American", supplemented with a rubber seal, provide tightness due to internal pressure, in this case, the union nut can even be tightened by hand. As for flat sealing options, it will be necessary to provide the necessary contact pressure.

Mandatory tightness of the connection can be provided by both a conical "American" and a flat one. At the same time, flat ones make it easy to change gaskets, which are not in short supply. And for conical ones, special gaskets are needed, which differ in a non-standard size. In turn, conical ones without gaskets should not be chosen, since in order to create a tight connection, it is necessary to tighten the nut very tightly, which is unacceptable if the pipes, for example, are plastic.

Conclusion

As you can see, an American in plumbing is already an indispensable part. That is why it is so widespread.

Menu:

An American with an internal or external thread is used by all experienced pipeliners. With this prefabricated quick-release pipe fitting, two risers can be securely connected.

The design is a collapsible combined coupling, the structure of which provides for the presence of 2 and a union nut.

American women types

The versatility of the device lies in the fact that the device is connected to the pipeline system with just one union nut.

Classification by purpose

According to the functional purpose and design, an American-type threaded connection can be:

• flat. This option is quite compact. The tightness of the connecting part is provided by a gasket. Over time, it is necessary to regularly tighten the nut, if necessary, change the used gasket. Given this fact, it is desirable to mount this type of connection in places with good access to it;
• conical. It is not equipped with a gasket, since the conical structures are highly polished, and when mounted they fit very tightly to each other.

Important! It is necessary to ensure that the deviation of the pipes along the axes does not exceed 5⁰. Otherwise, the bond may not be airtight.

Since the reinforcement part is used at very important joints of pipeline elements, it must be carefully checked for possible hidden defects.

Important! The conical type of product is considered more reliable. Therefore, with its help, they connect parts that must function flawlessly in conditions of sharp temperature changes.

Fastening using the design is increasingly being used in the laying of pipelines, pushing into the background the squeegee-coupling device with a lock nut.

Types of threads respectively

If we classify products by thread, then we can distinguish 3 types of connecting structures:

• "mom-folder";
• "mother-mother";
• "folder-folder".

Advantages

The fastening structure is different:

• reliability;
• fast, easy assembly and dismantling. By turning only the union nut, in a matter of seconds, the joint can be mounted without any rotation of the risers. This fastening cannot be compared with a squeegee-coupling type connection, for the implementation of which many different parts, tools, materials are required;
• the ability to create straight and angular joints;
• compactness;
• reusability, since the assembly-disassembly process can be carried out more than once, which does not affect the quality of subsequent fastenings.

The last two conditions entail significant cost savings, which is of great importance to most citizens.

In addition, due to the ease of installation, most manufacturers of plumbing equipment began to design branded faucets, meters, filters in combination with a fastening structure.

The versatility of the device lies in the fact that with different combinations of fitting connections, American straight and angular types are assembled to each other, designed for fastening pipes of various diameters. More often than others in such cases, GOST 8959-75 is used.

The use of cone-type devices makes it possible to ensure high tightness of metal-to-metal joints without using gaskets. This know-how helps to increase the service life of the parts.

Flaws

Probably the only "minus" of this is its high price. It is this factor that can cause the choice of a different type of fastening of the risers to each other. Although, it is also characterized by a high cost. So the choice is yours.

About connector assembly

Those who have not dealt with this connecting structure are often asked how to twist an American. Let's say right away that there is nothing complicated, you just need to have some information about the structure of the fastening unit and have elementary skills in working with keys.

So, to tighten the union nut, you can use an adjustable or regular open-end wrench.

Important! When installing the connection, do not use a gas (pipe) wrench, as the chrome or nickel coating may be damaged.

Important! When using union nuts with a decorative coating, plywood or plastic turnkey gaskets must be used. Otherwise, you run the risk of being left without decoration on the union nut.

If you need to fasten the metal-layer using the device, you need to use the internal key. Its cross section is a hexagon, it can also be in the form of a cylinder with two notches (engages). Used for mounting press fittings.

Internal key

When this device is not available, they use pliers, other improvised parts or tools. But the key still needs to be purchased if you are going to mount not one connection, but the whole system ().

Anyone with metal on “you” can make a key for a cone of the required size. The cone-shaped end of the tool is necessary in order to accurately get into the recessed hooks. The key is L-shaped with a handle length of about 150-160 mm. For its manufacture, profile fittings (trimmings) are used.

Mounting algorithm

Using an element of pipe fittings, it is quite easy to connect.

In order for the joint to be of high quality and last for many years, it is recommended to adhere to the following algorithm:

1. Make a drawing of the future pipeline, on which mark the locations of the connections, apply the distances between them.
2. Prepare pipes. That is, you need to cut them into the necessary pieces, chamfer.
3. Carry out calibration (editing) of the ends of the risers. This technological process is necessary in order to ensure high-quality pipe joints.
4. Install a fitting on the end of the pipe, tighten the fitting not very much, correct the correct installation of the part, and eliminate possible problems. If there are no distortions, and it is visually visible that the device is placed correctly, tighten the union nut.

Important! Try to tighten the union nut as tightly as possible to ensure that there are no leaks.

Those who work with the structure for the first time, and before that, for example, dealt with galvanized threaded fittings, may have doubts about the tightness of the fastening. To be sure, they wind the FUM tape under the thread or, although this is not necessary. The connection reliably seals the joints. Whoever connects the pipes at least once with the help of an American will use it all the time.

About Applications

The American fitting, like the polypropylene pipe itself, is used for the installation of various kinds of main pipelines.

It is used when laying:

• heating systems;
• plumbing for hot and cold water;
• gas pipelines;
• sewer systems, including magnaplast plastic sewerage, other pipelines.

American - the most common, convenient, reliable, in some cases an indispensable fastener.

When mounting a water meter at home, one cannot do without such a reliable part, since the “input” and “output” can be perfectly done only with the help of this fitting.

Important! The ease of use of the connection can be seen when dismantling the water meter for inspection or repair, since the fixture can be easily unscrewed.

When installing heating radiators, this fastening device cannot be dispensed with. In some situations, the fixture is the main node of the heat or water supply system.

When repairing radiators of a heating system, the use of a fitting significantly reduces repair time and simplifies system assembly.

The device is able to function efficiently in conditions of high pressures, sudden changes in temperature.

Due to the presence of various modifications of connecting devices, it is possible to quickly and easily fasten plastic and metal-plastic structures, metal and plastic products, plastic risers.

Using an American, you can mount almost any connection of pipeline elements.

In many cases, even those with a flange connection are successfully mounted. To do this, a thread is welded to the flange, after which they continue to connect the elements of the system with the help of an American. This is also what makes this truly versatile piece of pipe fittings unique.

The design fits perfectly with steel welded tees, steel bends, spurs, couplings, taps, steel pipes, and other parts of pipelines.

These and other elements of pipelines are used for laying risers in bathrooms, kitchens, country houses, and other buildings. The reliability of the connection with the help of an American makes it possible to install special bathroom furniture in the bathroom, since the possibility of direct contact with water is excluded.

A novice plumber or a simple layman can mount the fastening of risers using an American. It's all about the simplicity, and at the same time, the versatility of the connecting structure.

American… What is it? This name is a quick-release nut equipped with a thread. The design of the element includes 2 threaded fittings, a union nut and a gasket. An American is often used for pipe installation, as it provides a reliable and tight connection. This is a universal element, very often used during installation work.

The American can be used to install hot and cold water pipes, heating systems, technological structures intended for the transportation of non-aggressive substances.

Connection types

The conical type of fastening, performed by means of an American, has many advantages. In particular, the connection is sealed and reliable. It is resistant to temperature extremes and chemical environments. You can use an American even when the axes of the pipes deviate slightly. Even in this case, the installation will be of high quality and reliable.

A threaded connection is indispensable in cases where instant joining or dismantling of pipes and control parts is required. You can see the types of installation by looking at the photo.

The American nut is good because it can be used several times. To carry out repeated installation work, you only need to purchase a new gasket.

Characteristics

The American has a number of advantages over other fittings. With its help, you can undock the structure without using the rotation method. These elements are made from a variety of materials: polypropylene, stainless steel, cast iron, brass.

For installation using an American, a special key is required. You can either buy it in the store or make it yourself.

There are different sizes of this item. The choice of a particular one depends on the specifics of the work. The most commonly used American sizes are 12 and 34.

Through this element, you can connect both hard and soft lines of structures. The connection is of two types: direct and angular. This factor is very important for comfortable and quick installation.

The corner element allows you to perform installation work in hard-to-reach areas, fasten parts of different types and sizes together. The American makes it easier to repair the system. So, you can quickly dismantle the system without using an additional tool.

The part can be installed on pipes transporting hot and cold water, non-aggressive liquids. In this case, the temperature of the liquids should not be more than 120 degrees. The part is used for mounting elements with a small diameter.

In stores you can find different types of American women: with external and internal threads. The element can be mounted in any position. In this case, it is not required to take into account the direction of transport of the substance in the system.

The connection is made by means of wrenches of open-end and adjustable type. You can also use generic type keys. Pipe gas wrenches cannot be used in work.

The outer surface of the element consists of a nickel galvanic sheath. It is necessary in order for the part to have increased resistance to corrosion and mechanical stress. In addition, this coating also has an aesthetic meaning. With it, the element acquires a pleasing to the eye appearance.

Scope of use

This element is used for a wide range of applications. In particular, it is used for the installation of water supply structures, in heating systems. The excellent consumer qualities of the elements make them suitable for connecting any type of pipe. They are also used for repair work on radiators, and for the installation of water meters, and for the installation of shut-off valves, and for attaching structural parts, and for installing cleaning filters.

The advantages of the American are not only that it can be easily and quickly installed, but also during the further operation of the system. The part facilitates further repair work, dismantling.

Now you know all the necessary information about this irreplaceable part: what it is, where it is used, how the work is done. You can see what it looks like through the photo. You can see them on our website. The photo shows different types of parts, which will allow you to better navigate in the store with the corresponding products.

The quick-release threaded American is available with a flat or conical connection of structural parts. Usually, the simplest American consists of four parts: two threaded fittings, a gasket (but not always) and a union nut.
Tightness between fittings occurs due to the conical surfaces of the edges of the parts and a rubber gasket, or for flat ones - only with a gasket, for example, paronite.

Americans are designed for convenient quick connection or disconnection of pipes and various shut-off and control elements of heating and plumbing systems in the house. Connection (connector) of pipelines is carried out due to only one union nut. Please note that the American plug connection in plumbing is designed for repeated use with the replacement, if necessary, of the “squeezed out” gasket and has an undeniable advantage over the usual squeegee with a coupling and a lock nut.
Such connections come with a socket threaded connection (Photo 1)

or for soldering polypropylene pipes (Photo 4).

Americans for plumbing are made from different materials: cast iron (Photo 3),

brass plated with chrome or nickel (and without),

stainless steel and combined, with individual polypropylene parts. They can be bought in the distribution network of various sizes (diameters) and designs (straight, angular (Photo 2),

designed for different pressures of the medium in the pipeline.

Widespread cranes with an American.

By design, an American ball valve can be straight or angled and is designed to work in a system of cold and hot non-aggressive environments.

Available in bore sizes 15 (1/2″), 20 (3/4″) … and up to 50 (2″). The temperature limit for a plastic tap is plus 90 degrees. And a ball valve with an American made of brass, for example, Bugatti (Bugatti) can withstand temperature conditions, according to the manufacturer, from minus 20 to plus 120 degrees.

In order to install or dismantle plug-in connections, you need a wrench for American women. In plumbing practice, more often you have to deal with American women 1/2 ″ and 3/4 ″, with two internal protrusions, less often for a hexagon. I make such a “L” shaped double-sided key myself, from cutting construction profile 14 fittings, using the method of heating and flattening to a square. Then I give a small conical shape and harden. Under the cone is done because different manufacturers have slightly different sizes of internal protrusions.

The universal mutual “L” shaped key for American women has the following approximate dimensions (diagram in Fig 1):

handle length 150 mm;
edge under 1/2 "- A \u003d 12, B \u003d 10, C \u003d 32;
edge under 3/4″ - A = 16, B = 13, C = 35

Such a homemade wrench is also suitable for detachable connections for a hexagon.

Tip: if you only need to work with one or two ... 1/2 ″ metal American women, you can use ordinary pliers, which will work quite well as a key (Photo 5).
