Item Details

  • RADNOR™ Quick Connects provide fast, reliable and positive connections and quick disconnection for torches, hoses and regulators. All models are color-coded for gas service for added safety (oxygen/green, fuel gas/red, inert gas/blue). Oxy/fuel gas models include integral reverse flow Check Valves. Quick Connects fit all B-size welding and cutting equipment.


  • Brass construction provides long service life-cycle tested over 10,000 operations indicating a service life of 10 to 12 years of comparable use.
  • Non interchangeable Oxygen and Fuel Gas connectors prevent accidental gas mixing
  • Instant closure on reverse flow Check Valves with total shutoff at only 10 oz. of back pressure
  • Spring loaded locking mechanism responds to fingertip action and achieves a gas-tight connection.
  • Exceeds CGA-flow specifications- 1100 SCFH flow at 125 PSIG inlet pressure and 800 SCFH flow at 125 PSIG inlet pressure when 2 additional check valves are used in conjunction with the Quick Connects.
  • Double seal socket connection on second seal provides added safety protection.
