ASA Bolt Sets

These bolt sets and o-rings are used for mating ASA flanges. ASA flanges are simple, sexed vacuum seals for HV applications; one flange is grooved to accept an o-ring while the other mating flange is smooth (flat).

ASA Hardware Available:

  • Fluorocarbon O-Rings -- Sold individually; ideal for mating grooved to flat ASA flanges.
  • Buna-N Molded O-Rings -- A Buna-N o-ring mounted in an aluminum carrier; ideal for mating two flat ASA flanges. Two versions available; GL Series (standard) and G Series (differentially-pumped)
  • Bolt Sets -- All the necessary hardware (sans o-ring) for bolting ASA flanges together
