Simple sealing element used predominantly for static sealing.

FEP encapsulated O-Ring

An FEP encapsulated o-ring is a static sealing element and consists of an elastomer core ring, that is seamlessly encased in a FEP jacket. FEP is a perfluorinated polymer and like PTFE, provides excellent resistance against chemicals. The elastic pressing force is comparable to that of a normal o-ring. However, for the installation it should be considered that there are limits to the expansion and compression.

FEP encapsulated o-rings come in the same dimensions as elastomer o-rings and have similar installation parameters. It provides a good chemical resistance and due to its physiological harmlessness and sterilizability it is oftenly used in the chemical industry, petrochemistry as well as in the medicine and food industry.
