Fep Encapsulated Rubber O Ring

There are certain applications which prohibit the use of conventional rubber O-Ring Seals. The use of hostile chemicals or extreme temperature (both high and low) during various processes can make effective sealing very difficult. The main advantage Encapsulated O-Rings have over solid P.T.F.E. is that it has the chemical inertness whilst with its energising core, the O-Ring returns to its original form.
