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.
Zinc-plated steel plugs and sockets have better strength and durability 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. 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.

Hose Couplings for Hydraulic Jacks
Connect a hose to a ram or pump.
Quick Disconnect—High-pressure minimal spill couplings have a flat face, which ensures minimal fluid loss when connecting and disconnecting your hose line. They're double-shut-off style, so there is a valve in both the plug and the socket. To connect, push the plug into the socket until you hear a "click." To disconnect, slide the sleeve forward until the plug ejects.
