Ptfe Encapsulated O Rings

It has the lowest coefficient of friction of any solid material.

Ptfe encapsulated o rings.

The combination of these components creates an o ring that is virtually chemically inert and compression set resistant for use in harsh sealing environments. 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. 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. Ptfe encapsulated o rings ptfe encapsulated o rings ptfe is a superior o ring material not affected by most chemicals.

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. Kalrez costs an arm and a leg and ptfe while it may be chemically compatible very limited capability to recover after it has been compressed. Lubrication is less critical and can sometimes be omitted. Encapsulated o rings not all o rings are created equally.

Select from the various core options to satisfy your application. Ptfe encapsulated o rings comprise of an encapsulated core which has been seamlessly encapsulated in a jacket of ptfe. When it comes to chemical service applications viton has it s limitations. The encapsulated o ring is intended to close off potential leak paths between mating surfaces in both static and dynamic applications.
