PTFE Enveloped Gaskets

Properties and application

The sealing insert is made of corrugated stainless steel, soft gasketing material or rubber. This insert is coated with PTFE and open on one side, usually on the outside. Thanks to the high chemical stability, good mechanical properties and permanent resistance in the atmosphere (humidity, gases, temperature changes) they are suitable for all types of gaskets and different media, mostly for aggressive chemicals.

Advantages

Thanks to the high stability of C-F bond virgin PTFE, which is used for the envelope, exhibits extraordinary chemical resistance. Combinations of two or more insert materials allow a large number of different applications.
