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.

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.

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.

Plugs with barbed end are also known as E adapters. 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.

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

Made of plastic, these couplings are lighter in weight than metal cam-and-groove hose couplings, yet have the chemical resistance to withstand gasoline and other harsh substances. 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 rubber hose and secure with a clamp.

Nylon plugs and sockets have better strength than PVDF plugs and sockets. They have good corrosion and chemical resistance to handle gasoline and fuel applications. PVDF plugs and sockets have better corrosion and chemical resistance than nylon plugs and sockets. Use them when your application involves harsh acids and solvents.

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.

Cam-and-Groove Hose Couplings for Food and Beverage

Made of FDA listed materials, these couplings are suitable for food and beverage applications and won’t impart tastes or odors to the product. They also meet NSF/ANSI 61 safety standards for use with drinking water systems. 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 and sockets are polypropylene, which is lightweight with good abrasion and corrosion resistance.

Plugs with barbed end are also known as E adapters. Insert the barbed end into 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.
