What is a compression seal?
The compression seal is a pre -distorted piece of material designed to fit between two objects and prevent leakage under pressure. It is usually located between two surfaces that are screwed together, the compression seal fills in irregularities between mating. It also usually prevents gas or fluid leakage through small gaps or holes where surfaces are not perfectly smooth and smooth. The compression seals are commonly made of materials such as rubber, neoprene, graphite, silicon, felting, metal or plastic.
At the same time, the compression seal was often made of materials that contained asbestos. As asbestos turned out to contribute to asbestosis deadly lungs, materials in the United States (US) that contain asbestos are no longer used in the production of any type of seal. However, asbestos materials are still used in the production of seals, in other parts of the world.
A properly functioning compression sealing should not be made of material that is too strong. In general, the truth isSimilar, the thicker seal will allow leakage through the pores of the seal itself. The best seal thickness is strong enough to compensate for any surface irregularity and is still compressible.
While some types of sealing materials cannot be over-over- especially elastomer-based materials or rubber- other seals such as metal or Teflon®, can be overdoing, which can destroy their sealing properties. Metal compression seals must usually be able to regenerate or expand to work properly. If it is too tightened, the sealing of compression metal compression will lose this recovery and will not be able to provide seals.
The perfect example of the need for the correct tightening pressure of the metal seal is the head of the head installed on the engine in virtually all vehicles. Designed if you want to seal between the engine block and the cylinder head, the head gasket is commonly made of metal. AutomobIlů usually publish the right torque pressure that the mechanic should use for the screws that hold the engine together. This helps mechanics to replace the head gasket on the engine without excessive screws excessive, which can destroy the seal.
