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. All ARO plugs are compatible with any of the ARO sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

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 are easier to connect than sleeve-lock sockets. Connect by pushing the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Manifolds give you a centralized and mounted location for plugging in your air tool line.

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.
