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.

Made of metal, these couplings have better durability than plastic cam-and-groove couplings. A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug. Couplings are compatible with Andrews, Dixon, Ever-Tite, and PT cam-and-groove couplings.

Socket connectors and reducers are also known as C x C couplers.

Aluminum plugs and sockets are lighter in weight than 316 stainless steel plugs and sockets. They have good corrosion resistance. 316 stainless steel plugs and sockets have excellent corrosion resistance.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.

Metal Cam-and-Groove Hose Couplings for Water

A complete coupling consists of a plug and a socket (both sold separately) that allow you to quickly connect and disconnect medium-to large-diameter hose lines. To connect, insert the plug into the socket and press the levers down. The levers fit snugly into the groove on the plug’s body and force the plug against the gasket to form a tight seal. To disconnect, lift both levers and pull out the plug.

Socket connectors and reducers are also known as C × C couplers.

Aluminum couplings are lighter in weight than brass plugs and sockets. They have good abrasion and corrosion resistance. Brass couplings are softer than aluminum plugs and sockets, so they’re easier to thread together. They have good corrosion resistance.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Warning: Relieve all pressure before disconnecting the couplings. Do not use cam-and-groove couplings with compressed air or gas.
