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 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 and sockets 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.
