McMaster 5315K42 Zinc-Plated Steel Snap-Tite H-Shape Hose Coupling Size 3/4, Plug, 3/4 NPTF Female End

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.

Zinc-plated steel is stronger and more durable than other metals. It has fair 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: Never attempt to connect or disconnect couplings when operating at maximum pressure. Stop the flow before you disconnect the line.
