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.

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. Chrome-plated steel has fair corrosion resistance and has a bright, shiny appearance. Nickel-plated steel has good corrosion resistance. Aluminum is lighter in weight than other metals and has good corrosion resistance. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. Nickel-plated brass has better corrosion resistance than unplated brass. 303 stainless steel has very good corrosion resistance, so it’s the best choice for high-humidity environments.
NPTF (Dryseal) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Plugs and sockets with a push-on barbed end have sharper barbs than standard barbed hose fittings to grip rubber push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. To ensure proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.
Push-to-connect sockets join by forcefully pushing the plug and socket together until you hear a click. Unlike sleeve-lock sockets, you should not slide back the sleeve to connect. To disconnect, slide the sleeve on the socket forward until the plug ejects.

A complete coupling consists of a plug and a socket (both sold separately) 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.
Plugs are also known as nipples.
Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.
Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.

Plugs are also known as nipples.
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.
Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.
