F.E.P. Encapsulated Rubber O-rings

FEP FPM temperature range -20°C - 204°C
FEP Silicone temperature range -60°C - 204°C
An encapsulated O-ring comprises an elastomer energising core, which has a seamless jacket made from fluoropolymer.
The elastomeric core may be Fluorocarbon (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.

Recommended for use in:

Chemical Processing and Production
Oil Extraction (on shore and off shore)
Petrochemical Refining
Pharmaceutical Production
Food and Drink Processing
Paint and Die Manufacturing
Cosmetics and Perfumery
Automotive Components
Aerospace Engineering

Not Recommended for:

Dynamic use where high speeds and poor finishes are encountered.
Where the housing design requires excessive stretch or collapse of the O-ring during installation.
