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.

High-Pressure Thread-Lock Quick-Disconnect Hose Couplings for Hydraulic Fluid
A complete coupling consists of a plug and a socket (both sold separately) that thread together to form a stronger connection than other types of quick-disconnect couplings. To connect, insert the plug into the socket, then slide the sleeve forward and thread it onto the plug. To disconnect, unthread the plug from the sleeve, then slide the sleeve back and pull out the plug. All of the High-Pressure Thread-Lock quick-disconnect plugs are compatible with any of the High-Pressure Thread-Lock quick-disconnect sockets of the same coupling size, regardless of the pipe size. Couplings are compatible with Enerpac Series and Parker 3000 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.
Zinc-plated steel plugs and sockets are stronger and more durable than 316 stainless steel plugs and sockets. They have fair corrosion resistance. 316 stainless steel plugs and sockets have excellent corrosion resistance.
NPTF (Dryseal) 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: Stop the flow before you disconnect the line.
