FEP - encapsulated O-rings
FEP - fluorinated ethylene-propylene

FEP is a thermoplastic material with similar properties to PTFE. Seamless FEP-encapsulated O-rings have an elastic core in FPM or VMQ. They are used at very high thermal and chemical loads. The extremely high chemical resistance of the cover protects the elastic core material against the chosen medium. Another advantage of the cover is its very low coefficient of friction.

This results in a combination of very high chemical and thermal load-bearing ability and the elastic properties of standard commercial elastomers. The core material is chosen to suit the temperature range and medium.

Because of its limited flexibility, great care is required during installation. Warming the material in water or oil to between approx. 80ºC and 100ºC increases flexibility and supports the installation.

Depending on the core material, the temperature application range is from -55ºC to +200ºC.
