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.

Universal Quick-Disconnect Hose Sockets for Air
Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European. Use them with a plug of the same coupling size to frequently connect and disconnect your line. Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects. Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line. They are brass for good corrosion resistance.
Sockets with a push-on barbed end have sharp barb that 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.

Lincoln Quick-Disconnect Hose Couplings for Air
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. All Lincoln plugs are compatible with any of the Lincoln sockets, regardless of the pipe size.
Plugs and sockets with a shut-off valve have a valve that stops the flow when the coupling is separated, so air won’t leak from the line. Those with a clamp-on barbed end insert into a plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.
Plugs are also known as nipples.
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.
Zinc-plated steel is stronger and more durable than other metals. It has fair corrosion resistance, so it 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.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
