Quick-Disconnect Hose Couplings for Compressed Gas

Use these couplings to quickly link and unlink welding hoses, torches, and pressure regulators. They consist of a plug and socket that are sold together as a set of two—you’ll get one right-hand connection for oxygen and one left-hand connection for fuel gas. The connections are noninterchangeable and color coded so you can’t mix lines. The male threaded ends attach to threaded welding hose, and the female threaded ends attach to a torch or pressure regulator. To connect couplings, push the plug into the socket; the sleeve on the socket has a spring-loaded lock for gas-tight connections. To disconnect, pull back on the socket sleeve and twist to release the plug. The sockets have a shut-off valve that stops the flow when the coupling is separated so gas won’t leak from the line. The sockets also have a built-in check valve to prevent gas backflow. Couplings are also known as CGA (Compressed Gas Association) couplings. They are brass for good corrosion resistance.
Couplings with left-hand threads are identified with a notch in the nut.
Note: Couplings have a CGA number that corresponds to a specific type of gas. Make sure the CGA number of the coupling matches the CGA number of your tank and other system components.
