Specification :

Solid copper gasket to make a leak tight UHV seal between two conflat flanges. Oxygen free high conductivity ( OFHC) copper is normally used as this sealing material as it is very clean, can easily be formed to shape, has a wide temperature range, and has a low outgassing rate.

" OFHC" copper gaskets are not always needed for all requirements, we have a range of several different types of gasket materials can be used for most of the general UHV applications.
