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

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.
