ASA Tees (grooved flanges)

We fabricate these ASA tees from 304L stainless steel tubing and 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).

KF Tees Feature:

  • 304L stainless steel construction
  • Feature one rotatable flange on each axis (in any combination of flat & grooved)
  • Reducer tees adapt two different flange sizes
  • Common lengths and tube diameters listed; contact us with your specific requirements

Note:
  • These flanges are identical to the ISO NW flange standard. While these flanges are compatible with those made by European manufacturers, the tube diameter listed is in inches.
