A built-in shut-off valve stops the flow when the coupling is separated, so air or water won’t leak from your line. Also known as luer lock couplings, these 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. Couplings have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size. They are nylon, which is lightweight with good impact and abrasion resistance.
Note: For a complete coupling, order a plug and a socket.

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.

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.

Made of plastic, these couplings are lighter in weight than metal quick-turn couplings. 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 for easy installation in tight spaces.

They have a universal connection, so the plugs will connect to any of the sockets, regardless of the pipe or tube size.
Nylon plugs and sockets have good impact and abrasion resistance. Polycarbonate plugs and sockets are clear so you can monitor your line. Polypropylene plugs and sockets are moisture resistant and won’t absort water and lose strength, even in high-humidity environments.
Note: For a complete coupling, order a plug and a socket.

Also known as luer lock couplings, these consist of a plug and socket that connect to small-diameter tubing with a half turn. They have a compact body for easy installation in tight spaces. Insert tubing into the plug or socket and tighten the nut to form a seal. Couplings are open-flow style, so there is no shut-off valve to stop the flow when the coupling is separated. They are 316 stainless steel for excellent corrosion resistance.
Note: For a complete coupling, order a plug and a socket.
