Static Seals


Simple sealing element used predominantly for static sealing.

FEP/PFA encapsulated O-ring

A FEP/PFA encapsulated O-ring is a static sealing element and consists of an elastomer core ring, that is seamlessly encased in a FEP/PFA jacket. FEP/PFA 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/PFA 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.
