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.

Plastic Quick-Turn Tube Couplings for Air and Water
- For Use With: Polycarbonate Plastic: Air
Nylon Plastic: Air, Water
Polypropylene Plastic: Water - Temperature Range: Nylon Plastic, Polycarbonate Plastic: -20° to 200° F
Polypropylene Plastic: 35° to 150° F - Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber
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. 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.
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 absorb water and lose strength, even in high-humidity environments.
Note: For a complete coupling, order a plug and a socket.

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.

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.
