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.

Color/Shape-Match Quick-Disconnect Hose Couplings for Air and Water
Couplings are color coded by shape so you can’t mix hose lines. Only plugs and sockets of the same color and coupling size will fit together. 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. Plugs and sockets are brass for good corrosion resistance.
Plugs are also known as nipples.
NPSF (National Pipe Straight Fuel) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same color and coupling size.

Snap-Tite H-Shape Quick-Disconnect Hose Couplings for Hydraulic Fluid
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 hydraulic hose line. All of the Snap-Tite H-shape quick-disconnect plugs are compatible with any of the Snap-Tite H-shape quick-disconnect sockets of the same coupling size, regardless of the pipe size. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated.
Plugs are also known as nipples.
Sockets are sleeve-lock style. To connect, slide back the sleeve on the socket, insert the plug, and release the sleeve. To disconnect, slide back the sleeve and pull out the plug.
316 stainless steel has excellent corrosion resistance.
NPSF (National Pipe Straight Fuel) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.

High-Pressure Minimal-Spill Quick-Disconnect Hose Couplings for Hydraulic Fluid
These couplings have the highest pressure rating of all the minimal-spill couplings we offer. Also known as flush-face 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 when you need frequent access to a line. All of the High-Pressure Minimal-Spill quick-disconnect plugs are compatible with any of the High-Pressure Minimal-Spill quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with Snap-Tite 71 couplings. Also known as double shut-off couplings, the plugs and sockets both have a shut-off valve that stops the flow when the coupling is separated.
Plugs are also known as nipples.
Sockets are push-to-connect style. To connect, push the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.
316 stainless steel plugs and sockets have excellent corrosion resistance.
NPSF (National Pipe Straight Fuel) threads are compatible with NPT threads.
Note: To ensure a correct fit, make sure that the plug and socket have the same coupling size. Pressure ratings are given for static (constant) pressure conditions.
Warning: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
