KF to VCO® Adapter

Flange to VCO fitting adapters allow the mating of one type of flange system to a Swagelok VCO fitting. All of our flange to fitting adapters are manufactured from 304 series stainless steel (unless otherwise noted).

Flange to VCO Adapter Features:

  • VCO fittings feature an o-ring sealed in a groove on the face of the male connector which compresses against the surface of the gland
  • Adapters available with male and female VCO connectors terminating in either CF or KF flanges
  • CF flanged adapters are UHV compatible
