Rubber Gasket Rubber Hose and Bellow
Gaskets are mechanical seals that prevent leaks between separate substrate sections. They are occasionally made of metal because they must be durable enough to withstand extreme pressures and wear. (In fact, the phrase "bloing one's gasket" refers to the unwanted result that occurs when pressure builds up too much and a gasket ruptures or fails in some way.) However, many gaskets, such as o-rings, can be made out of synthetic rubbers or silicone.

Virgin PTFE is by far the least expensive of the three varieties, and is used in most general applications. Filled PTFE is a gasket material with a virgin PTFE base to which a substance is added during manufacture to improve the sealing characteristics of PTFE . This "filler" usually is glass or graphite particles although ceramics has sometimes been used. The resulting gasket material is strong, yet highly compressible with very good, though not universal, chemical resistance.
Expanded PTFE is virgin PTFE to which a stress resistance has been added by means of molecular rearrangement during manufacture. This process ensures that the molecular chains from which the PTFE is constructed, do not arrange themselves into set patterns. This means that expanded PTFE possesses no structural weakness (grain) and expands and contracts equally in all directions. Because no additives are required, expanded PTFE also possesses the unique chemical resistance of virgin PTFE.
