McMaster 5315K15 Zinc-Plated Steel Snap-Tite H-Shape Hose Coupling, Size 3/4, Sleeve-Lock Socket, 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 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. Sockets are sleeve-lock style: slide back the sleeve, insert the plug, and release the sleeve. Zinc-plated steel is stronger and more durable than other metals with fair corrosion resistance. NPTF (Dryseal) threads are compatible with NPT threads.
