How to restore a rubber gasket at home. Rubber that has lost its elasticity can still be restored

14.03.2013

No matter how sad it is, but every thing has its own lifespan. And tires are no exception. Later certain time, it begins to lose its shape, becomes dry and hard, cracks and crumbles. And quite often in such a situation, when, as soon as possible, you need to replace a damaged part, there is absolutely no time to go to the store for it, or there is simply no way. But, fortunately, it is still possible to urgently solve this problem. Consider in this article several ways to give rubber elements a second wind.

So, the materials you will need: glycerin, ammonia, kerosene and napkins.

Do not be surprised! It turns out that kerosene and ammonia can really help out when trying to resuscitate rubber parts. First you need to prepare a low concentrated solution ammonia. Then roll the long and narrow rubber seals into a spiral. And keep them in the solution for about half an hour. If kerosene is at hand, we carry out the same procedure, only the rubber should be in this solution for at least 2 hours. Result - the parts will become noticeably softer and, perhaps, even a little larger than before. After the solutions, rubber products must be washed in non-hot water, using a soapy composition, then rinsed in clean water and dry.

The masters also found a solution for a short-term renewal of seals on refrigerator doors. In this case, it is recommended to pour boiling water over the rubber. It is said that for some time the sealant regains its lost elasticity and sealing ability. And in order to consolidate the effect obtained, you can treat the rubber surface with a napkin impregnated with a silicone composition. However, we recall once again that the effect will not last long, so it is necessary to replace the obsolete part as soon as possible.

Many of us have already installed plastic windows for a long time. But not everyone knows that if the seals on double-glazed windows are properly cared for, they will last much longer. So, you just need to lubricate the rubber elements with a layer of ordinary glycerin or silicone every time you wash windows. And for the best result, it is better to use specially designed chemical compositions from window manufacturers. As a rule, they should be offered by employees of the company in which you place an order, immediately. Although, however, today it is not at all difficult to find such a solution on the Internet.

There are many ways to return rubber products to their previous state in which they are most convenient to use. Therefore, to the question of how to soften rubber at home, there are several answers at once. And to choose how to soften the rubber in each case will remain with the owner of the house. In the most famous and common method of processing the products under discussion, ammonia is used. Its main advantage lies in maximum efficiency, availability and low cost, because such alcohol can be purchased at the lowest cost at any nearest pharmacy. First, rinse the rubber part with water and immerse in a water-alcohol solution. It is prepared in proportions 1/1. For such a bath, about 30-40 minutes will be enough. After the specified time, the rubber will need to be washed again. clean water and dry thoroughly.

The second most popular method of softening rubber among ordinary people involves the use of castor oil. It is important to note here that its result will be quick, but short-lived. Therefore, it is worth paying attention to this method if it is required to soften the rubber for a short time. To begin with, the rubber product is washed with water and dried, and then completely thoroughly lubricated with castor oil applied to a soft cloth or cotton wool. It remains only to give the object time to impregnate and you can use it. The term depends on the size of the product and the thickness of the rubber. For miniature parts, just a couple of minutes of “rest” will be enough. By the way, if liquid silicone is at hand, then it is quite possible to use it. This tool gives exactly the same result of quick, but short-term softening for rubber products.

The next method, which tells you how to soften the rubber at home on your own, will be longer, but the effect of it will remain for long time. This will require a large saucepan or other container available for heating, in which you can place the rubber product completely. If the material has become very hard, it is best to boil it in salted water. Rubber is immersed in a saucepan with liquid, and then sent in this container to medium heat. You can use for such heating and a boiler. It is difficult to specify the exact time of the procedure, it will also depend on the size of the product and the degree of its “stubbornness”. To determine the deadline for its completion, you will simply need to periodically check the rubber with a wooden stick for softness.

But not only boiling will be effective for softening the products under discussion. It is possible to influence objects with high temperature in other ways. If, for example, a hardened hose cannot be put on desired pipe, then its end should simply be immersed in boiling water for a couple of minutes. The main thing is that immediately after that, have time to quickly install the part until it returns to its original state. High temperature very quickly affects the rubber, effectively steaming and softening it. If it turns out to be difficult to remove the used part, then you can heat it in other ways, for example, by applying a cloth soaked in boiling water or by acting with a jet of hot air from a hair dryer. After such procedures, the desired element will quickly pull together soft and pliable. The main thing is to protect your hands from exposure to high temperatures or boiling water. It is better to protect them first with thick gloves or in some other way.

But there are other ways to quickly and easily soften rubber using improvised means. For example, the most ordinary kerosene can help with this. It is known that he is able not only to soften the rubber, but to completely change its structure, returning the material to its former elasticity and pliability. That's why this way recommended by experts to those who would like to achieve a result that lasts for long term. It will be necessary to fill a container of the desired size with kerosene, and then immerse the rubber product into it. Do not immerse the object in cold kerosene, it is better to leave it at room temperature for a while. Usually a couple of hours in the substance under discussion is enough to soften various rubber products. As soon as the right time expires, and the kerosene will have the desired effect on the object, it will be possible to remove the structure from the liquid, rinse thoroughly under water and dry.

Unfortunately, rubber - the elastic material from which various sealing parts are made - loses its properties over time. It becomes rigid, deforms and begins to crack and crumble. If there is no replacement part at hand, the question arises of how to restore the elasticity of the rubber until it becomes possible to replace it.

Small rubber parts that have lost their elasticity over time can be “reanimated” with ammonia or kerosene. Roll long and narrow rubber parts into a spiral. Prepare a weak solution of ammonia and immerse the products in it for 25-30 minutes. If you use kerosene, keep the rubber parts in it for at least 1-2 hours. During this time, the rubber will not only become softer, but may also increase in size. After ammonia and kerosene, wash the products in warm water with soap, then rinse in running water and wipe dry.

How to soften rubber?

Rubber is used in many household structures: various hoses, seals, adapters, car parts. Over time, products made from this material fail, dry out, lose elasticity, and become inconvenient to use. You should not immediately buy new elements, you can try to soften the rubber at home.

Rubber elements under impact external factors lose their original properties, become less elastic, harden. Their further use will not bring the desired effect, seals, for example, will not be able to make the system completely sealed. The purchase of new rubber elements is sometimes difficult due to the lack of products of the required dimensions or their overpriced.

The following substances allow you to soften rubber:

Kerosene. Allows you to make rubber parts soft by affecting the structure of the material. After processing, the rubber element becomes fully elastic. Recovery technology is as follows:

fill a small container with kerosene (choose the container size depending on the size of the product to be restored);
place the part in a container with kerosene for 3 hours;
after the specified time, check the product for softness, if the result is satisfactory: remove the material and rinse with warm running water;
dry the material in a natural way, without using a hair dryer or battery.

Alcohol ammonia. The process of restoring old material is as follows:

dilute the indicated alcohol with water in a ratio of 1: 7;
place the rubber material in the resulting solution for half an hour;
after the specified time, remove the part and rinse with warm running water;
Allow the parts to dry completely before using them.

Please note: you can not keep the rubber in a solution of ammonia and water more than an hour. If the material does not become elastic after 30 minutes, use another recovery method.

Medical alcohol followed by the use of glycerin. The technology of "reanimation" of rubber parts:

fill the container with medical alcohol;
put in alcohol a part that needs to be restored for several hours;
after the specified time, check the condition of the product, if it is soft enough, remove the element from the solution and wash it with warm soapy water;
rub glycerin into the surface of the part using a sponge (cloth);
remove any remaining glycerine from the surface of the product.

Instead of glycerin, it is allowed to use automobile oil, it is rubbed into the surface of the product, then the part is kept for half an hour before use. Behind specified period rubber becomes quite elastic.

Castor oil and silicone. Let's make a reservation right away - this method allows you to quickly "reanimate" the old rubber, but the recovery effect will not last long, after a few days the product will become solid. For this method, follow the sequence:

smear the part with silicone;
wait 10 minutes;
after the specified time, the part can be used.

Note: a similar effect is achieved by using castor oil. It is rubbed into the surface of the part, after which it becomes soft and elastic.

There are situations when the rubber element is difficult to remove from structural parts due to its hardening. You can achieve the desired result by heating the rubber with a stream of hot air using a hair dryer. When exposed to high temperature, the material will become softer, it can be pulled out of the part.

Too "hardened" element is softened by boiling in salted water. The technology is as follows:

fill the container with salted water;
let the liquid boil;
place the rubber element in boiling water for 10 minutes;
remove the rubber and quickly use it for its intended purpose.

This method is quite effective, but has a short-term effect. When it cools down, the rubber becomes stiff again.

You can soften the rubber in the above ways. In this case, it is necessary to take into account: a long-term effect after restoration, has a method with kerosene. Rubber, after its application, remains soft and elastic for a long time, because the structure of the material changes. Other methods do not allow to achieve such a result.

It was the case it was necessary to soften the rubber. No matter what I tried, it's useless. But I didn’t know about ammonia, now I’m taking note, in case I need it again.

How to Restore the Elasticity of a Rubber Gasket

Do-it-yourself rubber restoration

I think that I will not reveal a big secret by saying that everything in the world eventually becomes unusable. Everything loses its original properties.

For example, rubber, over time it becomes stiff and loses its elasticity. But this is not a reason to thoughtlessly throw it away.

Everything can be fixed, restoring the elasticity of rubber will not be difficult.

What is it for in the first place? For example, the rubber gasket is numb, so you can buy it in the store.

Or rubber seals or cuffs have lost their softness, so you can also buy them. The era of scarcity is long gone.

But it turns out not quite so. IN small towns far from everything can be purchased, I'm not talking about villages and villages.

And besides that, buy tires desired shape it can be difficult due to the fact that there are many rare, almost unclaimed products that are sometimes not easy to buy in a store.

So how does rubber recovery work? And kerosene will help us in this matter.

For small items, for example, take rubber cuffs (sealing), rubber gaskets, various rubber seals, etc. and prepare a kerosene bath for them.

Pour kerosene into a small container and place the objects to be restored there for a couple of hours.

If rubber big size, then first it must be carefully rolled up and placed in kerosene.

It will not be superfluous to say that the restored rubber will regain its former softness, and it can be reused.

Still, the new is better than the old.

If sooner or later a new rubber cuff or rubber gasket catches your eye, then it will be right to buy new products and replace the old ones.

Rubber is a fairly elastic material from which various sealing products are made, however, unfortunately, over time, this material gradually begins to lose its properties. In this case, the rubber becomes very hard, loses its original properties and gradually begins to crack. And if there are no replaceable parts at hand, then in this case a person has to face the question - how to restore the former elasticity of rubber. By the way, Rti is sold on the website www.rti-project.ru.

Small rubber parts that have lost their original elasticity can be easily restored with kerosene or ammonia. At the same time, long and too narrow details should be coiled. After that, prepare a weak solution of ammonia and put the product in it for half an hour. However, if you do not have ammonia, and you will use kerosene, then in this case the rubber product should be in this solution for at least two hours. Only the fate follows that during this time the rubber will not only become much softer, but also significantly increase in size. After that, you should treat the product in warm water with soap, and then you need to wipe the rubber dry.

If the door rubber seals of an old refrigerator have lost their original elasticity, then many craftsmen advise them to pour boiling water over them. This method will help restore the former properties of this rubber. In order to fix this effect, wipe the rubber with a cloth soaked in silicone. However, this is only a temporary measure, so replace the seal on the door as soon as possible.

In order for the rubber seals on double-glazed windows to last as long as possible, it is necessary to periodically apply a layer of glycerin or silicone on them. By the way, glycerin can be easily purchased at any pharmacy.

With the onset of the autumn-winter season, I began to understand that in order to maintain visibility at a normal level (especially at night, which is very much in winter), it is necessary to change the wipers.

The old wiper blades practically ceased to fulfill their function - they jumped on the glass, creaked, left streaks.

After the previous replacements, I was left with 5 pairs of old wipers with the same symptoms. Each of them has already worked out its own and was sent to retire with the above symptoms (creaking, jumping on glass, etc.). And among them there are SWF, Champion, and noname.

Before buying new wiper blades, I decided to experiment with old wipers. After reading on the Internet what car owners advise, I conducted an experiment.

1. Take an old wiper blade. We check the gum for mechanical wear - the presence of gaps and other obvious defects in the wiper gum. If everything is OK, go to step 2.

2. We check the frame (all articulated joints, the place of attachment to the lever) for backlash. If nothing hangs above the allowable limits, go to step 3. If the janitor by itself has already become loose, then most likely - into the furnace.

3. Carefully degrease the gum.

I had white spirit and a clean rag at hand, with the help of which the gum was carefully wiped off everything that had accumulated on it during the period of operation, and there was a lot of dirt on it.

4. Spray / smear the gum with silicone grease.

This should restore elasticity to the elastic.

5. After rubbing the gum with silicone grease, leave it in this state for a while. (several hours, days, etc. who cares how much). I waited 2 hours because I had to go.

6. Before starting operation, wipe the gum again with white spirit (neatly, and not as in paragraph 2), thereby removing the remnants of silicone grease from it so as not to smear it on the windshield, because. This obviously does not improve visibility.

If the silicone grease remains on the rubber band, then the wiper will also glide well, but not only on glass, and on water, which is on windshield, through the mud sticking to it, and through the frozen ice - it’s generally excellent. Just don't wipe anything.

7. We try. My wipers wiped the glass without squeaks and passes (strips). After the experiment, 3 days have passed - the effect of the new wipers has not disappeared.

How long these brushes really last after the procedures done - time will tell.

I liked the result. The purchase of new wiper blades has been postponed for the time being. indefinite time, given my stockpile of used wipers (good thing I didn't throw them away)

They also recommend turning the rubber band on the old janitor upside down, but for this you need to pull it out first, for which you need to try a little. The above procedures were enough for me, without turning the gum over.

P.S. The property of silicone grease to restore the properties of rubber is confirmed.

In many cases, rubber products are completely irreplaceable. Various seals, belts, hoses and other parts are found in the design of household items and automotive technology. But with prolonged use or hypothermia, they can become hard and unsuitable for further use. How to soften rubber at home? There are substances and methods of exposure that help achieve the desired result.

This substance is able to change the structure of rubber and restore the elasticity of rubber products. The procedure consists in soaking objects until the desired effect is obtained. Large size rubber can be carefully rolled up before being placed in a container of kerosene. After a couple of hours, the softened part must be removed and rinsed thoroughly.

There is another option - to arrange the product bathing in a water-ammonia solution. The rubber should be placed in the prepared composition and kept for about half an hour. Then the washed and dried part can be used for its intended purpose.

What can soften the rubber at least for a while? Silicone will have a temporary effect on it. Having lubricated the surface of the object with it, it is necessary to give time for absorption, after which the product will be ready for use. A similar treatment can be carried out with the use of castor oil.

In a situation where it is not possible to put a hose on a rounded part or pipe, immersion of the desired part of the product in boiling water will help. After waiting a little, you need to remove the hose from the water and, without wasting time, install it in the right place. It will be easy enough to do this, because the material will steam out from the high temperature.

Sometimes there is a problem with the removal of rubber elements from some structural parts. In this case, air heating will be effective. A hair dryer is used. Under the influence of a hot jet, the material will expand, as a result of which it will be possible to scroll and pull off the pliable element.

Such simple methods you can soften hardened rubber, thereby increasing the service life of popular products.

Has it ever happened that the rubber band around the cards simply broke with age, your favorite sneakers became hard as a stone, or did the vacuum cleaner fail due to the fact that a small pad, belt or cuff hardened in it? If yes, you know that rubber becomes hard over time. Natural rubber loses its properties and hardens under the influence of temperature, oils and even oxygen. As a result, one way to slow down the hardening of rubber products is to limit exposure to heat, oils, and oxygen. In the same time correct use heat and oils allows you to partially restore the softness of rubber products, although it is impossible to completely stop the hardening.

Steps

How to prevent hardening

Inspect rubber products regularly. Any rubber object, whether it's a wiper blade on a car windshield or an elastic waistband from your favorite pajamas, slowly but surely becomes hard. White or colored marks on the rubber may indicate that a chemical reaction is taking place.

Look for signs of damage. Cracked rubber will remain cracked even if the product is softened. In case of cracks, you can use a rubber patch or just buy a new item. There are no miracles in this situation.

Keep your rubber products clean. Protecting products from oxygen, temperature fluctuations and light is quite difficult, but you can regularly wash the plaque so that the destructive oils do not destroy the rubber object.

Store the rubber product in an airtight container to slow down hardening. If possible, remove the air (and with it the oxygen) from the container before packaging.

Store the container in a cool, dry and dark place. The same place where apples and potatoes are usually stored will do.

How to soften rubber with heat

Select your preferred heat source. The easiest choice would be an oven or hair dryer, but some people prefer to place rubber-soled shoes on a radiator. Make sure the oven supports low temperature heating, and the hair dryer uses a high heat setting to get approximately equal temperatures.

Place the item in the oven at a low temperature. In case the oven overheats and the rubber begins to melt, it is better to place the product on a baking sheet or a suitable form (one in which you do not cook food).

Warm up the rubber with a hair dryer. Shoes with rubber soles should be heated for 7-10 minutes at the highest temperature of the hair dryer.
- Do not keep the hair dryer in one place and constantly monitor the condition of the rubber to prevent melting and other destruction.
- Check the temperature carefully as the rubber gets very hot. Again, it's best to use an infrared thermometer.
Leave the rubber to cool for 10 minutes. Then try the product by touch. With luck, the rubber will remain soft and pliable even when it cools down.

Completely replace the fittings, and neighbors can be flooded.

Answer from a lion[guru]
buy a new one, it costs a penny and adjust the valve

Answer from Alex Mishin[guru]
There is absolutely no need to replace all fittings - it is enough to replace the trigger shut-off valve, colloquially often referred to as a "pear".
Depending on the design of the tank, it is either screwed onto a wire hook-shackle, or (in newer tanks) it is pulled onto a plastic tube that serves as a trigger handle - a “pear” for one and for another case you need to buy a different one that you need - look necessary.
The pear not only becomes hard, but also begins to crumble, and sometimes falls from one side - soaking it in gasoline-kerosene will not help. Although it would get wet normally - the rubber is vulcanized and therefore will not completely dissolve, but only swell.
If you send a picture of your tank inside, I'll try to tell you which release valve you need.
Valve price - from 5 rubles.
