FEP Encapsulated O Rings

FEP Encapsulated O-Rings

An encapsulated O-ring comprises an elastomer energising core, which has a seamless jacket made from fluoropolymer. The elastomeric core may be Fluorocarbon (Viton/FPM or Silicone). The jacket is made from Teflon® F.E.P. (Fluorinated - ethylene - propylene).

Why are Encapsulated 'O-Rings needed?

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.
