Product Description

To make a leak tight UHV seal between two conflat flanges, a gasket is required. OFHC (oxygen free high conductivity) 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.
