The basic seal for the CF flange system is an oxygen free electronic grade (OFE) and high thermal conductivity (OFHC) copper gasket that is compressed between the knife-edges of two CF flanges to create a seal capable of achieving ultra high vacuum pressures. Copper gaskets have a temperature range of –200 ̊C up to 450 ̊C. These gaskets are precisely punched, de-burred, chemically treated and packaged to eliminate and prevent surface imperfections. CF copper gaskets provide one reliable seal per use. Use a new copper gasket each time you install a CF sealing assembly.
