PTFE Encapsulated O-Rings Viton®/FKM or Silicone
Encapsulated o-rings are o-rings consisting of a seamless and uniform PTFE encapsulation which completely encloses a rubber core material. Elastomer/rubber core material are a choice of Silicone or FKM. The combination of these components creates an o-ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. This combination of chemically resistant polymer jacket over a low-compression set elastomer provides unique properties for a range of demanding applications.
