CF to NPT Adapters

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

Flange to NPT Adapter Types:

  • CF to NPT Female: Zero length style (center-bored CF flange)
  • KF to NPT Male:
    • Flanged stubs terminating in a tapered thread
    • 304 stainless steel
  • KF to NPT Female:
    • Suitable for insertion of an NPT threaded (male) pressure gauge or UTA valve into a foreline.
    • Available in 304 stainless steel, brass and aluminum.

NOTE: Use PTFE tape for sealing threaded joints.
