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. Brass is softer than other metals, so it’s easier to thread together. It has good corrosion resistance. 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 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.
