CF Flanges and Components

CF Flanges (ConFlat) are a commonly used flange in high and ultra-high vacuum applications. A gasket (typically copper) is used between the flanges. The faces of the two mating CF flanges have a machined knife edge, which cuts into the softer metal gasket, providing an extremely leak-tight, metal-to-metal seal.
