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.

Temperature Range: -30° to 250° F
Tubing: Use with firm or soft (Durometer 35A-90A) Buna-N rubber, EVA plastic, gum rubber, latex rubber, neoprene rubber, polyurethane rubber, PVC plastic or silicone rubber, except for fittings with pipe end

With no latch, these couplings have a compact design to fit in small spaces. They connect with a push and disconnect with a pull, so you can easily access your line. Couplings consist of a plug and a socket (sold separately). They have a universal connection, so the plugs will connect to any of the sockets regardless of the pipe or tube size. They are nickel-plated brass for very good corrosion resistance.

Note: For a complete coupling, order a plug and a socket.

Plastic Quick-Disconnect Tube Couplings for Air and Water

Lighter in weight than their metal counterparts, these quick-disconnect couplings are plastic. They consist of a plug and a socket that allow you to frequently connect and disconnect your line.

Latch-lock sockets disconnect by pressing the latch.

Twist-lock sockets connect and disconnect with a twist and do not have a latch.

Acetal plugs and sockets are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. Plug and Sockets with shut-off have a valve to stop the flow when the coupling is separated, so air or water won’t spill from your line.

Note: For a complete coupling, order a plug and a socket with the same coupling size.

Through-Wall Sockets, Barbed Tube

Temperature Range: -40° to 180° F
Tubing: Use with soft or firm (Durometer 70A-85A) polyurethane rubber

Barbed plugs and sockets insert into tubing. Those with collar do not require a clamp and limit the size of the tubing to a maximum of 1/8” OD.

Through-wall plugs and sockets are also known as bulkhead and panel-mount plugs and sockets; they mount through your wall or panel to create an inlet or outlet.

Multiline Quick-Disconnect Tube Couplings for Air

Don’t get your lines crossed—use one of these couplings to quickly connect or disconnect multiple tubes at once. They keep tubes organized and optimize space in tight spots. Often used in robotics, these couplings are ideal for complex pneumatic systems.

Through-wall couplings allow you to connect and disconnect air lines on a panel or machine. This is useful when you are going to transport and reconnect your equipment on site.

Modular couplings let you customize your setup. These sets include five components, each with two connection points. Combine the components as desired with the included joining pins for a coupling with up to 10 connection points. You can also change component orientation or offset the connections, which helps prevent joining the wrong lines.

Barbed-connect fittings are for soft tubing. Push-to-connect fittings are for firm and hard tubing. Also known as instant fittings. To connect to tubing, insert the tube into the fitting—an internal gripping ring and O-ring hold the fitting in place. To disconnect, push on the release ring and pull the tubing out of the fitting.

Keyed couplings prevent mixing and matching the wrong lines, since they’ll only connect with a plug or socket that is keyed the same.

For a complete coupling, order a plug and a socket with the same coupling size.

To connect the coupling, slide the latch to the lock position. To disconnect, slide the latch to the open position. Made of plastic, these couplings are lighter in weight than brass couplings.

To install in a panel, machinery, or bulkhead, add a through-wall adapter ring (sold separately).

Temperature Range: 25° to 140° F
Tubing: Use with firm or hard (Durometer 50D-70D, Durometer 91A-97A) FEP plastic, nylon plastic, PFA plastic, or polyurethane rubber

To connect the coupling, tighten the included clamp bolts using a L-key (not included). Loosen the clamp bolts to disconnect. Made of brass, these couplings are more durable than plastic couplings and have good corrosion resistance.
