CF Fittings

CF fittings seal with a knife-edge machined into the mating flange. Typical seal is an OFHC - (oxygen free high conductivity) copper gasket, although elastomer seals can also be used. The name CF is short for ConFlat. CF flanges are used in vacuum and ultra high vacuum (UHV) applications.
