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.

Impact-Resistant Thread-Lock Quick-Disconnect
Hose Couplings for Hydraulic Fluid
Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line. The threads engage as you tighten the coupling, overcoming the pressure gradually rather than all at once. To limit fluid loss when you connect and disconnect them, they both have flat faces for a close fit, as well as shut-off valves that stop flow. This is why they’re known as flush-face and double shut-off couplings.
A complete coupling consists of a plug and socket (both sold separately). Sometimes referred to as wing-style couplings, the socket has a wing nut that makes it easy to tighten and loosen these couplings by hand. Make sure to thread the socket until it's covering the O-ring on the outside of the plug.
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.
