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.
Aluminum couplings are lighter in weight than brass plugs and sockets. They have good abrasion and corrosion resistance thanks to their anodized finish. 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.

Plastic Cam-and-Groove Hose Couplings for Water
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.
Plug connectors and reducers are also known as SA spool adapters.
Sockets with locking levers prevent accidental disconnection. The locking pins engage automatically when the coupling is connected. Press the locking pins simultaneously to disengage.
Plug-to-socket reducing adapters are also known as A × C couplers.
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.
Aluminum fittings are lighter in weight than 316 stainless steel fittings. They have good corrosion resistance. 316 stainless steel fittings 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.
