The PCU Series 91 Tube Quick-Connect (TQC) Coupler is designed for easy installation onto the end of straight tubing either manually or by use of automated equipment.

For manual operation, slide the coupler onto the tubing until seated and pull the sleeve back to make a positive, leak-free seal. To release, simply push the sleeve forward. The field-proven cam locking device grips uniformly-firm but gently without damage to steel, copper, brass, or plastic tubing.

the long-life tube seal reduces couple maintenance costs and can easily be replaced. The seal accepts out of roundness conditions up to 2%.

The Series 91 TQC hold pressures from 25 micros up to 500 psi, proof pressure 4000 psi.

A built-in valve automatically vents system pressure before the coupler can be removed from the tube for operation safety. Blow off or loss of sealed connections are eliminated.

Five internal parts are quickly interchangeable allowing the same connector body to fit all three tube sizes. This simple interchangeability allows for changing refrigerants and oils.

Seals are available in Neoprene, Nitrile, and Fluorocarbon for specific applications.
