About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Industrial Quick-Disconnect Hose Couplings for Air

A complete coupling consists of a plug and a socket (both sold separately or in a set) that connect and disconnect quickly. Use them if you need frequent access to a line. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

Steel is stronger and more durable than other metals. Zinc-plated steel has fair corrosion resistance and should be used primarily in dry environments. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Twist Sockets, Barbed Hose

Maximum Pressure: 300 psi @ 72° F
Maximum Vacuum: 26 in. of Hg @ 72° F
Temperature Range: -40° to 225° F
Attachment Type: Use Worm-Drive Clamps or Band-and-Buckle Clamps
Specifications Met: ISO 6150/B

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.

Plugs and sockets with a clamp-on/crimp-on barbed end insert into rubber hose and secure with a clamp or a crimp-on hose ferrule.

Twist sockets connect by inserting the plug into the socket and sliding the socket forward until it locks in place. To disconnect, slide the sleeve back while twisting it left and right; the twisting action vents the downstream air to release pressure, making it safe to remove the plug.

Plastic Quick-Disconnect Tube Couplings for Air and Water

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments. A complete coupling consists of a plug and socket; choose a set for both, or select a plug and socket separately. Because they're quick disconnect, they're helpful for lines you frequently need to access.

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

Plugs 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.
