How to Identify and Measure Fittings
Pipe size is an industry designation, not the actual size. View information about how to measure threaded and unthreaded pipe and pipe fittings.

Brass Quick-Turn Tube Couplings for Air

An all-brass body gives these couplings better strength and durability than plastic quick-turn couplings. They have a nickel plating for extra protection against corrosive environments. Also known as luer lock couplings, they consist of a plug and socket (sold separately) that connect with a half turn. They have a compact body, so they’re easy to fit in tight spaces. Plugs and sockets are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.
Note: For a complete coupling, order a plug and a socket.

- Temperature Range: -100° to 300° F
- Tubing: Use with soft or firm (Durometer 35A-95A) polyurethane rubber, PVC plastic or silicone rubber
Barbed plugs and sockets insert into tubing and secure with a clamp.
