ASA flanges, adapted decades ago from 150# steam-pipe flanges, are simple, sexed vacuum seals—one flange is grooved to accept an o-ring while the mating flange is smooth.
ASA flanges are limited (by the o-ring's properties) to applications with temperatures between ~0° C and 120-180° C and pressure from atmosphere to ~10-7 torr or mbar. These flanges are sized by the connecting pipe's nominal I.D. in inches. The normal range is: 1", 1.5", 2", 3", 4", 6", 8", and 10". They have large diameter bolt holes through the rim; consequently, for any given tube diameter, ASA flanges have much larger O.D.s than other flange types.
NOTE: When buying ASA flanged fittings and components, always compare dimensions carefully. When purchasing flanges to mate to an existing item, have that item's flange O.D., I.D., number of bolt holes, bolt circle diameter, and the handy o-ring groove I.D. for quick reference.
