Encapsulate O-rings are o-rings consisting of a seamless and uniform Teflon® FEP/PFA encapsulation/jacket which completely encloses a core material of either silicone or Viton® elastomers. The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments.
