CF to Quick-Connect Couplings

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

Flange to Quick Connect Coupling Adapter Features:

  • Makes a vacuum joint with any smooth-surfaced standard O.D. tube
  • Commonly used to attach tubulated ion or thermocouple gauges to a system
  • Adapters available in either CF or KF flange terminations
  • Dual coupling versions ideal for easy fluid circulation

Notes:
