FEP Encapsulated O-Rings FEP fluoropolymer encased elastomeric cores

FEP Encapsulated

FEP Encapsulated O-rings

FEP Encapsulated O-Rings have an elastomeric core either Viton (fluorocarbon) or Silicone that is completely covered with a seamless sheath of FEP fluoropolymer.

They show excellent resistance to a wide range of media and low friction.


Recommended for use when a standard elastomeric O-ring has inadequate chemical resistance for a specific application. Also when a solid PTFE O-ring does not offer sufficient elasticity.

Mainly used in the chemical, petrochemical, food and pharmaceutical industries. Another common application is refrigeration units because the encapsulation protects the core rubber from the refrigerant.

The clear Teflon FEP encapsulation complies with Part 177 of Title 21 of the Food and Drug Administration regulations for safe use as articles or components of articles for producing, manufacturing, processing, preparing, treating, packing, transporting or holding food in accordance with FDA regulation 21.CFR.177.1550.

Furthermore, the clear Teflon FEP encapsulation of our encapsulated O-rings is compliant to NSF 61 requirements. We can also confirm that our FEP encapsulated O-rings are compliant to EU VO 1935/2004 and 10/2011 certification.

In Conclusion these O-Rings are an inexpensive solution to many critical sealing applications.
