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.
Plugs with barbed end are also known as E adapters. Insert the barbed end into plastic or rubber hose and secure with a clamp.
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.

Quick-Disconnect Hose Couplings for Chemicals
Made of polypropylene, these couplings are lightweight with excellent chemical resistance to withstand acids and solvents. Also known as flush-face couplings and minimal-spill couplings, the plugs and sockets have a flat face, which allows them to mate close against each other, reducing fluid loss when connecting and disconnecting the line. A complete coupling consists of a plug and a socket (both sold separately) that connect and disconnect quickly. Use them if you need frequent access to a line. All of the quick-disconnect chemical plugs are compatible with any of the quick-disconnect chemical sockets of the same coupling size, regardless of the pipe size. Also known as double shut-off couplings, the plug and the socket both have a shut-off valve that stops the flow when the coupling is separated, so fluid won't leak from the line.
Plugs are also known as nipples.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Couplings consist of a plug and a socket (sold separately) that join with a latch, so you can frequently connect and disconnect your line. To connect, insert the plug into the socket; to disconnect, press the latch on the socket and remove the plug. Plugs and sockets are polypropylene, which has excellent chemical, impact, and abrasion resistance.
Plugs and sockets with shut-off have a valve to stop the flow when the coupling is separated so fluid won’t spill from your line.
Note: For a complete coupling, order a plug and a socket with the same coupling size.
