ASA Flanges and Fittings

ASA vacuum flanges provide a complete range of fittings to mount with tubing sized from 1 to 12 inches in diameter. The flange system consists of two flanges, a sealing ring, and bolt fasteners to compress the seal between the two flanges. A pair of ASA flanges must have one grooved flange to accept the sealing ring and one smooth face flange onto which the seal will be made.

ASA (American Standard Association) flanges are also known as ANSI flanges, named for the updated association’s name of the American National Standards Institute. ASA/ANSI vacuum flanges and fittings are available in two general styles: fixed and rotatable. By offering these two styles, ANCORP allows for users to create effective flange matings by rotating bolt hole orientations to align with fixed bolt holds. This feature alleviates concerns regarding limitations set forth by fixed bolt hole orientations.

Improving compatibility across mating pairs, ANCORP offers grooved options for both fixed and rotatable flanges. All ASA/ANSI sealing assemblies must include one smooth face and one grooved face flange.

ANCORP ASA Flanges and Fittings  are rated for high vacuum to 1 x 10-8 Torr. Made of 304 stainless steel with an FKM O-ring for sealing, ASA flanges can be used in applications from -20° to 200° C.
