Stainless Steel Quick-Turn Tube Couplings for Air

Made of stainless steel, these couplings stand up to wet 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.
303 stainless steel couplings have very good corrosion resistance. 316 stainless steel couplings have excellent corrosion resistance.
Note: For a complete coupling, order a plug and a socket.
