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.

For Use With: Polycarbonate Plastic: Air
Nylon Plastic, PVDF Plastic: Air, Water
Polypropylene Plastic: Water
Temperature Range: Nylon Plastic, Polycarbonate Plastic: -20° to 200° F
Polypropylene Plastic, PVDF 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 absort 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.

Quick-Turn Couplings for Plastic
and Rubber Tubing—Chemicals

For Use With: Acetic Acid, Bleach, Nitric Acid
Temperature Range: 35° to 150° F
Tubing: Use with soft (Durometer 40A-65A) PVC plastic or silicone rubber, except fittings with male threaded pipe connection and plugs for sockets

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 for easy installation in tight spaces. Plug 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. Made of PVDF (also known as Kynar), they have excellent chemical resistance.
