Teflon Encapsulated O-Rings Viton®/FKM
A Teflon Encapsulated o-ring is a circular shaped seal with a round cross section consisting of two components, a Teflon® jacket and an internal (core) energizer, which imparts memory to the seal. The encapsulated O-ring is intended to close off potential leak paths between mating surfaces in both static and dynamic applications.
FKM Core with FEP Jacket This choice gives the best possible sealing characteristics due to the very low compression set value of the specially formulated FKM core. Unless there are extreme high or low temperature involved, FKM core should be the first choice.
Teflon FEP Encapsulation with FKM Core: 300F/149C to -10F/-23C
