Gaskets for heating radiators: variations, selection and

Heating

To create reliable hermetic joints between sections of heating radiators, various types of gaskets are used. The element must have a number of specific properties that provide a safe service for a certain time.

Intersection seals for batteries are made from different materials.

Product types

In most cases, all components are purchased with the purchase of the batteries themselves. In a hardware store, consultants are required to know what gaskets are needed for bimetallic radiators, and which ones are needed for cast iron products. But often the buyer is solely for parts. Therefore, it does not hurt to prepare to get what you need.

Paronitovye elements

Paronite is a modified rubber.

They are made from pressed rubber with the addition of asbestos fibers and powder materials.

Intersection radiator gasket of this type is most often used in apartments with central heating.

  1. Perfectly maintains temperature condition in + 85-100? .
  2. The most popular is the product made according to GOST № 15180-86. For the production of used paronite PMB, PON-B and PC, as well as reinforced paronite.
  3. Products are made by cutting on a press or cutting circular scissors, as well as a plotter.

General Purpose Paronite Gaskets

  1. Such seals are effective for pipelines with liquid and gaseous media.

Note! Such gaskets for cast iron radiators are used in pipes with water, steam, various solutions, as well as oils. Do not react to inert gases, ammonia in different states, alcohol, nitrogen, oxygen.

  1. Are they designed for temperatures from -50? up to +450 ?.
  2. They are equipped with the marking of PON-B and GOST No. 15180-86.

Oil and gas resistant analogues

  1. It is recommended for pipelines with transportation of oily liquids and gases.
  2. It is better to use them where the coolant, which is a technical oil, as well as petroleum products, hydrocarbons in a liquefied or gaseous state, melted wax, coke oven gas, nitrogen, and oxygen, pass through.
  3. Temperature range of -50? up to +450 ?.
  4. Marked as MBP.

Acid resistant modified rubber

  1. Keeps tightness in flange connections of the pipelines transferring aggressive connections, for example - antifreeze.
  2. Gaskets work effectively when in contact with acids and alkalis, organic solvents and various gases.
  3. Sustain from -50? up to +250 ?.
  4. Provided with a PC brand.

Reinforced products

It looks like reinforced products.
  1. The gasket supplied with a reinforcing mesh for a cast iron radiator is mounted into the intersectional space of household batteries as well.
  2. Steam, water, various gases, oily substances seal keeps perfectly.
  3. Temperature mode -50? up to +450 ?.
  4. PA marked.

Other types of gaskets

In the photo silicone seals.

Less commonly used, but no less effective seals as well as those described above, are suitable not only for domestic purposes.

Modern intersectional gasket for the radiator is not destroyed when exposed to aggressive substances.

  1. Silicone Accessories withstand high temperatures. Thanks to good ductility, they successfully compensate for the expansion of metal sections under the influence of heat. More common in systems with low pressure and stress.
  2. Fluoroplastic analogues are made of heat-resistant polymers. Do not require additional lubricants, do not react to hot water, and antifreeze.
  3. Cardboard gaskets also in demand. They are impregnated with oil paint to enhance the life and positive properties. In particular, the instruction recommends installing them in the spaces between the sections in bimetallic and aluminum batteries.

Competent selection of seals

Seals have different sizes.

For installation of batteries in a private house or apartment, experts advise to buy silicone or paronitovye seals. It is undesirable to make gaskets with your own hands, especially from scrap materials.

This can lead to a quick depressurization of the joints. Spend a tiny amount on the finished product, especially since the price just does not hit the wallet.

Products have certain sizes. This is the thickness and diameter of the outer and inner circle. Track the coincidence of the diameters of the rings and the outlet holes of the pipes.

Note! The “margin” sealer, in which the edges protrude too strongly, will soon become unusable. Therefore, take strictly to size. The thickness of the inserts for cast iron batteries is 1.5-2 mm, for bimetallic and aluminum - from 1 to 2 mm.

Independent installation of sections

The gasket directly seals the nipple.

Often there is a need to add, or replace part of the sections in the battery. Mark in advance which segments are to be replaced and prepare the tools.

You will need a radiator key, as well as gaskets and nipples (hollow elements with left or right two-way thread).

  1. Spread out on a flat surface (preferably on the floor) sections face down.
  2. Remove the end caps from the plugs.
  3. Put the gasket on the part of the nipple where there is no thread.
  4. Screw the nipple into the manifold for two or three turns carefully.
  5. Lightly press the nut into the hole of the segment to be joined.
  6. Use the wrench to tighten the nipple. Multidirectional thread will pull both sections of the battery. With proper tightening, the gasket will tighten securely at the junction to the desired limit.
Replacing sections in the radiator.
  1. The lower and upper nuts must be tightened by the same number of turns in turn. Then you will avoid distortions.
  2. Before installing the radiator in the heating system, check the tightness of the joints by letting water from the hose into the radiator. Joints must be dry.

Conclusion

Proper installation of industrial gaskets will save you from unpleasant moments with leaked batteries. Timely replacement of seals will extend the life of the heating system.
