Teflon o ring, PTFE o ring, PTFE Gaskets is made by plunger extrusion of suspension polymerized PTFE resin. Among all the existing plastics, O Rings PTFE Gasket has the best corrosion-resistance. Lead insulating sleeve, corrosion-resistant Teflon gaskets, and corrosion-resistant insulating Teflon gasket for different corrosive conditions, heat exchanger.
Because Teflon is a hard plastic rather than a stretchy elastomer, it is uncommon to see an o-ring that is made entirely of Teflon. However, there are applications where Teflon is the perfect material. For example some automotive steering systems use Teflon o-rings for fittings and they are also used in paint guns. (By the way, a tip on installing these rigid seals is to heat them in hot water before the installation so they will be slightly bigger and slip on easier.)
When someone says they want Teflon o-ring they may actually be talking about Teflon encapsulated o-ring. Here the Teflon is made into a jacket or sleeve that will completely enclose an elastomer which has the desired mechanical properties needed for the o-ring, such as resistance to cold flow. Since Teflon is practically chemically inert it allows the o-ring to resist almost all chemicals and will not allow corrosive fluids or gases to harm the elastomer.
The extremely low coefficient of friction of Teflon makes the encapsulated o-ring an ideal choice where surface wear might otherwise be a problem. By itself, the material Teflon exhibits a useful service life from below -100°, to temperatures of over 500°. Its resistance to solvents remains excellent throughout a wide range of temperatures. In addition, the low dielectric constant and electrical resistance also remain intact throughout this range.
