ConFlat (CF) and Wire Seal UHV Flanges and Fittings

ConFlat (CF) and wire seal flanges are part of the same family of ultra-high vacuum (UHV) components that compress a copper or elastomer gasket between two stainless steel flanges to create a vacuum-tight seal.The CF flange system is more commonly used within the vacuum industry and as such has a much larger standard product offering with faster delivery. Wire seal flanges are desirable for those applications that require flanges larger than those available with the CF flange system.

ANCORP CF flanges are manufactured to industry standards and are interchangeable with all other ConFlat style flanges and fittings, while wire seal flanges have no standard dimension specifications. Vacuum component manufacturers endeavor to create interchangeable wire seal flanges; however, it is recommended to purchase a mating set of flanges from one manufacturer to ensure compatibility. Standard CF flanges are available in 304L and 316LN stainless steel. Other materials such as 316L stainless steel and 6061 T6 aluminum are available upon request.
