ConFlat (CF) Copper Gasket DN300CF, Flange OD 14, Inner Diameter 11.8, Outer Diameter 12.31

The copper gasket is captured between mating CF flanges. Copper gaskets are made from high-purity, oxygen free 1/4 hard copper which is de-burred, chemically treated and individually packaged to avoid oxidation. If you are operating at a pressure below 10-8 torr, o-ring sealed compression ports limit the system pressure because of leakage and permeation.
