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 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 male threaded end are also known as F adapters.

Plugs with female threaded end are also known as A adapters.

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

Sockets with locking levers prevent accidental disconnection. The locking pins engage automatically when the coupling is connected. Press the locking pins simultaneously to disengage.

Sockets with male threaded end are also known as B couplers.

Sockets with female threaded end are also known as D couplers.

Sockets with barbed end are also known as C couplers. 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.

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.

Industrial Quick-Disconnect Hose Couplings for Air

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. They are also known as industrial interchange couplings. All Industrial plugs are compatible with any of the Industrial sockets of the same coupling size, regardless of the pipe size or barbed hose ID.

Nylon has good corrosion resistance, is nonmarring, and won’t scratch delicate surfaces. Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.

Push-Button Sockets, NPT Male Threaded Pipe

Maximum Pressure: 175 psi @ 72° F
Temperature Range: 5° to 160° F
Specifications Met: ISO 6150/B

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.

Push-button sockets are the easiest to connect and disconnect. Push the plug into the socket until you hear a click. To disconnect, push the button on the socket and the plug will eject.

Temperature Range: 5° to 160° F
Specifications Met: ISO 6150/B

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.

Push-button sockets are the easiest to connect and disconnect. Push the plug into the socket until you hear a click. To disconnect, push the button on the socket and the plug will eject. Safety push-button sockets release the compressed air prior to ejecting the plug to reduce hose whip.

Tru-Flate Quick-Disconnect Hose Couplings for Air

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 Tru-Flate plugs are compatible with any of the Tru-Flate sockets of the same coupling size, regardless of the pipe size or barbed hose ID. They are also known as automotive couplings.

Sockets have a shut-off valve that stops the flow when the coupling is separated, so air won’t leak from the line.

Plugs and sockets with a barbed end insert into plastic or rubber hose and secure with a clamp or a crimp-on hose ferrule.

Push-button sockets are the easiest to connect and disconnect. Push the plug into the socket until you hear a click. To disconnect, push the button on the socket and the plug will eject.

Nylon has good corrosion resistance, is nonmarring, and won’t scratch delicate surfaces.

Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size.
