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 polypropylene, these couplings are lighter in weight than metal cam-and-groove couplings and have good abrasion and corrosion resistance. 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.

90° elbow sockets with female threaded end are also known as LD couplers.

90° elbow sockets with barbed end are also known as CL couplers. Insert the barbed end into plastic or rubber hose and secure with a clamp.

Curved 90° elbow plugs are also called sweep elbows. Their rounded shape reduces flow disruption by minimizing back pressure on the seal and conserving momentum through the 90° turn. They’re particularly useful when there are solids suspended in the water.

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.

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.

Metal Cam-and-Groove Hose Couplings for Chemicals and Petroleum

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.

90° elbow sockets with female threaded end are also known as LD couplers.

90° elbow sockets with barbed end are also known as CL couplers. Insert the barbed end into plastic or rubber hose and secure with a clamp.

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.
