Viton Gaskets

Viton Gaskets for CF Flanges

These Viton Gaskets are made in a flat cross-section using a vacuum grade fluorocarbon elastomer gasket seal, lathe cut, deburred, cleaned and packaged to prevent shedding or rips. Not intended to be a permanent seal. These are for use during routine mounting and unmounting of CF Flanges.

Our Viton gaskets are good for High Vacuum (HV) applications to 1X10-8 Torr. Rated for -20ºC to 150ºC (intermittently to 200ºC), these Viton gaskets are used to seal between the knife-edges of two identically sized CF Flanges.

These Viton gaskets may require slight stretching to fit in the Conflat CF Flange groove. When installing on flanges that are vertical, a small dab of vacuum grease will help keep the Viton o’ring in place.

Maximum Torque is rated to 7-10 ft-lb.

These Viton gaskets can be re-used several times as an economical alternative to copper gaskets (usage varies with time). However, if you are operating below 1X10-8 Torr, please use our copper gaskets instead! Not suitable for UHV applications.
