ASA Flanges & Fittings
ASA (ANSI) 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. To ease system assembly, rotatable flanges are available for bolt hole alignment.
All flanges offered by ANCORP are manufactured on state-of-the-art CNC lathes to ensure consistancy with dimensional tolerances and extremely fine surface finishes. Flanges are cleaned in an ultrasonic de-ionized water-based cleaning system and vacuum packaged free of visible particulates and oils, ready for immediate use in any vacuum application.
