Engine Gasket Builder
General information
Due to the multiplicity of static gaskets, only those types of particular importance to the engine will be dealt with in detail here. In general, they are used within a broad temperature range from - 200C to + 1,000C, depending on whether they are made of rubber, organic or inorganic fibers, minerals, metals or combinations of these. In addition to being resistant to high temperatures, they are expected to fulfil their function with the utmost efficiency and for prolonged periods of time.
In the latter case, this means that they must not undergo any detrimental changes under the effects of operating fluids, pressure or temperature. With only a few exceptions, they should not absorb any operating fluids, since these give rise to swelling and the softening of the sealing material, possibly leading to secondary damage and, in consequence, a loss of mechanical stability or dimensional changes resulting in leaks.
The gasket must neither relax excessively ( i.e.lose too much of its original thickness) nor become brittle, since both conditions are associated with a risk of leaks or blowout failure. Since many static gaskets, particularly in engines, are subject to additional dynamic stresses from vibrations or relative movements of the mating components, they must also possess extreme mechanical strength. Finally, they should be inexpensive, easy to store and handle and be capable of being installed automatically.
