Ptfe Encapsulated O Rings

Encapsulated o rings not all o rings are created equally.

Ptfe encapsulated o rings.

When it comes to chemical service applications viton has it s limitations. Fep ptfe encapsulated o rings combine ultimate chemical resistance of fep ptfe with the compressability of rubber or steel spring core. Ptfe encapsulated o rings ptfe encapsulated o rings ptfe is a superior o ring material not affected by most chemicals. Ptfe encapsulated o rings comprise of an encapsulated core which has been seamlessly encapsulated in a jacket of ptfe.

Encapsulated o rings are offered in two ptfe grades fep and pfa with a selection of three different energizers which give the user a choice depending on temperature and operating environment. Lubrication is less critical and can sometimes be omitted. Select from the various core options to satisfy your application. It can be used at temperatures up to 500 f 260 c.

It has the lowest coefficient of friction of any solid material. Ptfe encapsulated o rings are o rings consisting of a seamless and uniform ptfe fep pfa encapsulation jacket which completely encloses a core material viton fluoroelastomer also available in silicone. An o ring seal is a means for closing off a passageway preventing an unwanted escape of a gas or fluid and comes in a donut shape. The combination of these components creates an o ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments.
