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.
Sockets with a push-on barbed end have sharp barbs 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 a proper connection, the barbed end has to be pushed in all the way, with the hose end concealed by the ring.
Sockets with a crimp-on barbed end insert into rubber hose and secure with a crimp-on hose ferrule.
Sockets with a safety exhaust bleed excess air pressure to prevent hose whip. To start flow, slide the outer sleeve forward. Exhaust pressure before releasing the inner sleeve by pulling the outer sleeve back.
Manifolds distribute air to multiple lines. They're aluminum to resist corrosion. Four-outlet manifolds have two inlets. You can close off one of the inlets with the included brass pipe plug.
Brass sockets have good corrosion resistance.

European Quick-Disconnect Hose Couplings for Air

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. 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 European plugs are compatible with any of the European sockets, regardless of the pipe size or barbed hose ID. Made of zinc-plated steel, all are strong and durable, have fair corrosion resistance, and should be used primarily in noncorrosive environments.
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. They 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. The sleeve is made of zinc-plated brass, which has better corrosion resistance than zinc-plated steel.
Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
