Viton® (Fluorocarbon, FKM) Gaskets may require slight stretching to fit in the Conflat Flange CF groove. Also, it is recommended to use a small amount of vacuum grease to help keep the O'Ring in place.

Operating at a pressure below 10-8?
Viton O Ring sealed compression ports limit the system pressure because of leakage and permeation.
In this case, use CF Copper Gaskets instead!
