Gaskets for heating radiators: types, selection and installation. Which gasket for a heating radiator is better - types and manufacturing methods Rubber gaskets for aluminum radiators efficiency

Why are gaskets used when installing heating devices? Which of the gaskets sold in plumbing stores is better? Is it possible to make them from scrap materials yourself? Finally, how to properly install or replace them? Let's figure it out.

Application

The products we are interested in are used in two ways:

  1. The intersectional radiator gasket ensures the tightness of the connection between sections. It is pulled together by a nipple - a short tube with counter-directional threads - and clamped between the cut planes of the upper and lower collectors.
  2. In addition, gaskets are used when installing radiator plugs on aluminum and bimetallic heating devices.

However: in the latter case they can be replaced by winding.
It can be used as plumbing linen impregnated with silicone or paint, FUM tape or polymer thread-sealant.

Varieties

Material

Gaskets for cast iron heating radiators are made from paronite (heat-resistant hard rubber) in accordance with the requirements of GOST 15180-86. The standard regulates the main dimensions of products (by the way, not only paronite ones) and their weight in batches of 1000 units.

Gaskets for bimetallic radiators and aluminum batteries can be made from both paronite and heat-resistant silicone.

Which of the two materials is more preferable?

It is difficult to give a definite answer.

  • Due to its rigidity, paronite more effectively resists the internal pressure of the coolant;
  • Silicone, on the other hand, does not lose elasticity over time and requires less force when tightening to reliably seal the joint.

The photo shows a silicone product.

Dimensions and shape

The paronite gasket for a cast iron radiator always has the shape of a flat ring.

Products intended for aluminum and bimetallic batteries, can take the form of either a flat ring or a toroid (donut).

Note: Toroidal silicone gaskets are used to seal the ring groove sections.
If you try to squeeze them between sections or between a cork and a section with a flat surface, you will encounter the silicone being squeezed out.

The diameter of the hole in the flat gasket is determined by the type of radiator and the diameter of the nipple. The nipple is supplied with threads of the following sizes:

Self-production

An intersectional gasket for any type of radiator can be made independently. Yes, the price of these products is low; however sometimes long distance before the store, a weekend or a holiday may make you concerned about looking for alternatives.

The material we will use is a regular tube for a pneumatic tire:

  • Automotive - for a cast iron battery;
  • Bicycle - for aluminum/bimetallic.

For cutting, use regular scissors; The outline is first transferred to a camera cut lengthwise and laid out on a flat table with a ballpoint pen.

If you have an old camera and sharp scissors, you don’t have to go to the store.

However: if you need to make a large number of gaskets, it makes sense to speed up the procedure for their manufacture by making a punch from a punch sharpened on one side of the appropriate size (DN32 or DN25).

Problems

List typical problems radiator gaskets are small:

  • When installed under a plug, paronite or silicone can be squeezed out on one side. This happens especially often in cases where the thread axis of the plug or section deviates from the perpendicular to the plane of the collector end.
  • Paronitis with long-term operation under conditions of strong heating, it loses some elasticity. As a result, after several dozen cycles of heating and cooling of the sections, the intersection gaskets are capable of leaking when the batteries cool down again: a decrease in temperature leads to a slight change linear dimensions sections.

Installation and replacement

Under the traffic jam

How to install a gasket under the radiator cap of an aluminum battery with your own hands?

  1. Lubricate the end of the section collector and the plane of the plug with any neutral lubricant. Silicone plumbing grease, grease and even liquid soap will do.
  2. Place the gasket onto the threads of the plug.
  3. Tighten the plug with an open-end or adjustable wrench. The paronite tightens until the force becomes noticeable (but by no means insurmountable: you risk tearing off the sections). The silicone is pulled until the edges are visible squeezing out from under the cork.

Intersectional

Instructions for eliminating intersectional leaks are somewhat more complicated.

  1. Shut off the heating riser and remove the plugs or open the vents. If there are valves on the connections to the battery, simply close them.
  2. Place a basin or other container with low walls under the lower blind radiator cap, unscrew the cap a few turns and allow the remaining water to drain. Unscrew the plug completely; If necessary, use a stick or any other handy tool to free the lower collector from dirt.

Attention: blind plugs in most cases have left-hand threads; they unscrew clockwise.

  1. Repeat the operation with the top plug.
  2. Mark on the radiator key the distance from the edge of the battery to the nipple you need.
  3. Insert the key into any of the manifolds and, turning, push it into the radiator until it engages with the desired nipple.
  4. Unscrew one turn. The direction of rotation is the same as that of the cork.
  5. Repeat the operation with the nipple on the second manifold.
  6. Unscrew the nipples one turn at a time, one at a time. If unevenly unscrewed, the skew will jam or tear the nipple.
  7. Remove the outer sections; put new gaskets on the nipple and thread the nipple onto one thread.
  8. Install the end sections, press them against the nipples and use a wrench to tighten the latter until securely engaged.
  9. Collect heating device in reverse order.

Conclusion

As you can see, the installation operations are not complicated and, if necessary, can be performed by a beginner. The video in this article, as usual, will provide you with additional topical information. Good luck!

For sealed and quality connection heating radiator sections use special sealing gaskets. They can significantly extend the life of radiators and avoid leakage of coolant from the heating circuit. What kinds of gaskets there are for heating batteries will be discussed further in the material.

Types of sealing gaskets

On the modern market you can purchase a gasket for a heating radiator of absolutely any type - made of cast iron, aluminum or bimetal.

Depending on the material of manufacture, the following types of products are distinguished:

  1. Silicone gaskets. Such products are resistant to high coolant temperatures and well compensate for the thermal expansion of the metal. Such gaskets are usually used in autonomous systems heating systems with low operating pressure.
  2. Paronite products. They are made from pressed rubber containing asbestos and special powder. Such gaskets are used in radiators connected to centralized system heating, where the coolant temperature can rise to 90-100 ℃. Paronite gaskets are suitable for cast iron heating radiators, as well as for aluminum and bimetallic products.
  3. Fluoroplastic gaskets. This type of product is made from heat-resistant plastic. They are intended for installation on bimetallic and aluminum radiators, without prior lubrication. They are characterized by high heat resistance, resistance to aggressive factors and pressure changes.
  4. Cardboard spacers with impregnation from oil paint for durability they are used for aluminum and bimetallic radiators in autonomous heating systems. The production of products is regulated by GOST No. 9347-74.

Radiator gasket selection process

When deciding which gaskets to use for heating, you need to take into account not only the material from which they are made, but also the size.

The size of the product is determined by the following indicators:

  • internal section of the gasket (d);
  • outer diameter (D);
  • product thickness (s).

It is worth noting that the internal cross-section of the intersection gasket for the radiator must completely coincide with the size of the inlet hole on the radiator section. It is also desirable that the edges of the gaskets do not extend beyond the section - otherwise, coolant leakage may occur in these places.

Manufacturing methods

According to their shape, gaskets for cast iron batteries can be flat or convex. They are used for different types designs.

In particular, flat sealing elements are made from sheet materials such as plastic, rubber, paronite or leather. In their production, methods such as cutting with a stamp or punching knives, as well as cutting with a laser or circular knives are used.


Convex gasket for cast iron radiator and any other metal varieties Batteries are produced using thermoforming from polyvinyl chloride, as well as by vulcanization of raw silicone or rubber.

Cutting blanks using the stamping method

In the process of work, special stamps are used, that is, special devices precisely adjusted to the right size and consisting of several elements. In addition, a press is used to cut out blanks, on which a stamp is installed.

Before starting production, it is necessary to take into account the dimensions of future gaskets - for large products you will need a more massive stamp and a powerful press.

It is worth noting that this method of manufacturing sealing gaskets is considered cheap and highly productive. Due to this, it is used for mass production.

Application of punching knives

The operating principle of this method is similar to die cutting, but in this case a simpler and less expensive tool is used. The production of seals in this way is inexpensive and quite fast. However, the pants are quite short-lived, so this technique is used for the production of small and medium-sized batches of gaskets.


Cutting with circular knives

Only round seals can be produced using this method. large sizes. In the process of work you will need fairly cheap and high-performance equipment. Cutting is carried out with standard blades. Therefore, the production of gaskets of this type can be done independently and to any extent. Radiator leaks are often caused by a damaged gasket. And if you don’t know what to do if the heating battery leaks, first of all you should pay attention to the gaskets.

Laser cutting

In the presence of software, using standard laser machines, it is possible to produce gaskets of any shape and size.

However, the method has one small drawback - not all materials can be easily cut by a laser. To cope with more dense materials, it is necessary to reduce the cutting speed, which significantly increases production costs.

Thermal molding

In this case, you will need an injection molding machine with a mold for casting products. The cost of a molding press is quite high, so in order to make production economically feasible, the production of gaskets using this method must be large-scale or even mass-produced.


The production of products in small batches using this technology is relevant only if they cannot be produced in any other way. It is noteworthy that only PVC seals are produced by thermoforming.

Curing

To carry out vulcanization, special molds and a heat press are used. It is noteworthy that this type of mold is much cheaper than the analogues used in injection molding machines. This significantly affects the cost of production.

At the same time, the vulcanization process takes quite a long time, which also affects the price finished product. But durable rubber or silicone products can only be made this way.

In conclusion

Thus, intersectional sealing gaskets on radiators various types ensure their durability and efficient operation. When selecting a gasket, it is necessary to take into account its type and scope of application.

Cast iron battery overhaul.

Based on materials from "About pipes.ru".

After ten years of service, cast iron batteries look so that it simply hurts the owners to look at them. The paint wears off and peels off, plaque appears on the nipple connections, and sometimes radiators leak due to wear of the intersection gaskets. Owners are beginning to seriously think about replacing heating appliances. But what to buy? Bimetal is expensive, aluminum and steel will last much less. My thoughts return again to cast iron radiators. But they already exist! If you find the time and effort to restore cast iron batteries, they will look and work no worse than new ones. So why pay more?

The updated cast iron battery will last for decades

What to do if radiator intersection gaskets are worn out

Gaskets are the weak point in sectional batteries. Their task is to prevent coolant from leaking out of the radiator. Most often there are paronite gaskets, but in older models they are made of rubber, and sometimes the joints are wrapped with tow and paint to make them tight. When the material wears out, unsightly rust marks appear and the battery may begin to drip. This is not a reason to throw away the heating device, because you can simply replace the gaskets. This will require strength, time, patience and ability to use tools. Financial costs are minimal.

Preparatory work - cleaning internal channels

Over the years, batteries have accumulated a huge amount of dirt. It gets into the internal channels along with water and sticks to the walls. The resulting growths impair the heat transfer of heating devices. Therefore, restoration work begins with flushing the radiators. The batteries are removed, transferred to a bathtub or outside and thoroughly washed with a hose connected to water tap. If the procedure is carried out in a bathtub, then it is necessary to place a grate on the drain. Be prepared for a frightening discovery: the canals are turning into real trash.


The inside of the batteries looks something like this. Can't do without washing

How to properly disassemble an old cast iron radiator

After cleaning the internal channels, the battery is disassembled. For this you will need:

  • workbench or boards for equipping the workplace;
  • radiator key and plumbing key No. 2 or 3;
  • hammer and chisel;
  • blowtorch;
  • brush with metal bristles.

The battery is placed on a workbench or boards and the joints between the sections are heated blowtorch. Over the years of operation, the connection materials become stuck. Due to heating, microcracks appear in the gaskets, making the joints easier to disassemble. Remove the plugs from the radiator and unscrew the sections. This must be done carefully and evenly, gradually unscrewing the nuts from above and below, otherwise the cast iron may burst due to distortions. Sometimes the nipples have to be knocked out using a hammer and chisel.


Key for radiator plugs and adapters

Replacement of gaskets and assembly of the heating device

After disassembling the radiator, replace the gaskets and reassemble the sections. It is better to replace the gaskets with paronite ones. They will last the longest. If you can’t purchase them, use sanitary flax. It is wound onto a thread: on the right - clockwise, on the left - counterclockwise. As additional protection special sealants are used to prevent leaks. If the coolant has a chemically aggressive composition (for example, antifreeze is used), then you will have to choose a stable sealant; only paronite gaskets should be used. The radiators are assembled in the reverse order, only the direction of rotation of the key changes.


There are several types of gaskets for radiators, paronite ones are the most reliable of them.

How to make old batteries look aesthetically pleasing

Once you have cleaned the inside of the batteries and replaced any worn gaskets, the job of upgrading the functionality is complete. It's time to take care of the appearance so that the heating devices fit well into the interior. To do this, just paint them. If desired, the batteries are decorated with original painting, images using the decoupage technique, or simply covered special screens. But you will have to paint it anyway. It is important to choose the right paint composition and follow the application technology.

Subtleties of choosing radiator paints

Radiator paints are subject to increased requirements. They must be resistant to impact high temperatures, wear-resistant, safe. It is also important that the coating does not reduce thermal conductivity. Manufacturers offer the following compositions:

These are organic based paints. With their help it is easy to create a beautiful coating with a glossy shine. Disadvantage: pungent odor. Until the paint dries, a specific aroma will be felt in the room.

Advantages – big choice shades, good performance characteristics, durability. The drawback is the same - the smell. Moreover, it can appear when the batteries are very hot during the heating season.

They are often chosen due to their lack of odor and quick drying. When purchasing, pay attention to the manufacturer. There must be a mark on the can that the paint is intended specifically for heating radiators.

They are sometimes bought for batteries, but this is the worst choice. Oil formulations have many disadvantages. They take a long time to dry, smell strongly, change color, and reduce the heat transfer of radiators.


Make sure that the paint you choose is marked “For heating radiators” and “Heat resistant”

Radiator paint application technology

The coating must be removed before painting. Stores sell special paint removers, you can use them. In theory, washes help clean batteries, but in practice their effectiveness leaves much to be desired, because the paint literally sticks to surfaces under the influence of high temperatures. It is better to heat the coating with a blowtorch or a hair dryer, clean it with a spatula and a brush with metal bristles. After this, sand the surface with sandpaper and degrease.

You need to paint it like this:

  • First they paint internal surfaces to prevent drips from appearing on the front of the battery.
  • The brush or roller is applied from bottom to top.
  • Drips are removed immediately before the paint thickens.
  • The coating is applied to the entire surface of the radiator; there is no need to leave unpainted areas.
  • You can make a single layer coating, but it is better to paint in two layers to achieve greater durability.

An old cast iron radiator can create comfort in your home for several decades. Do not throw away the device if it has lost its presentable appearance and began to heat worse. All problems can be solved. Restore the battery, show your imagination - and the heating device will work and look no worse than new.

Gaskets for heating radiators: types, problems, replacement method

Why are gaskets used when installing heating devices? Which of the gaskets sold in plumbing stores is better? Is it possible to make them from scrap materials yourself? Finally, how to properly install or replace them? Let's figure it out.


Gaskets have long ceased to be in short supply: the necessary products can be found in any plumbing store.

Gaskets for heating radiators: types, problems, replacement method


Gaskets for heating radiators: video instructions for DIY installation, features of intersection products for bimetallic, cast iron batteries, what

Lining seals on a heating radiator is an issue that is relevant both when installing new equipment and when urgent replacement connection that has leaked. In order to install the system efficiently and protect your home for the next 20 years, you need to approach the choice of sealant with all responsibility. Let's figure out what the plumbing market offers for heating radiators.


What are we compacting?

A fitting or threaded fitting is a connecting element between the battery and heating pipes. It is the futorka, despite its insignificant appearance, is a key link in the heating system of a house or apartment. From the way you compact threaded connection with a footer, comfort and .

The fitting is a nut or bushing with an outer and external thread for connection with pipes of different diameters.

When do we compact?

Typically, footers are sold together with gaskets - rubber, paper, paronite, silicone. In theory, the gaskets should help seal the threads and protect against leaks. In fact, they are practically useless. So, only a professional can make a seal with a silicone gasket. When tightened, this material tends to “come out” of the thread and you have to unscrew and reassemble the connection several times. Rubber gaskets work until the first pressure surge, they quite often break and, as a result, let water through.

Our advice is to get rid of the gaskets that come with the footer and replace them with a stronger “product”. Forewarned is forearmed. Make a connection immediately and forever.

What do we seal with?

There are materials on the market for sealing the battery casing different generations. Until now, flax is considered the most common. Linen winding is a classic of the genre, and this is the first thing that a plumbing store can recommend to you. But don't rush to be charmed by the low price. The combination with flax tow is a thing of the past. And not only because today the market offers much more civilized tools. The system itself has changed. If earlier the pressure in pipes reached a maximum of 8 atmospheres and connections on flax had nothing to fear, then in modern high-rise buildings when crimping pipes, the pressure reaches 16 atmospheres. Is it possible to talk about protection here? Flax, moreover, requires additional impregnation in the form of paint or a special composition (red lead on drying oil, for example). The paint that held the tow tightly in Soviet years, can no longer be found, and red lead is not sold on every corner.
