About Measuring Fittings

Measure the threaded ends of your fittings to identify their pipe size, thread size, schedule, and thread type. Then, find compatible components.

Pioneer Quick-Disconnect Hose Couplings for Hydraulic Fluid

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 Pioneer quick-disconnect plugs are compatible with any of the Pioneer quick-disconnect sockets of the same coupling size, regardless of the pipe size. Plugs are compatible with the Parker or SafeWay socket series listed. 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 and sockets are zinc- or chrome-plated steel, which are strong and durable with fair corrosion resistance.

Plugs are also known as nipples.

Sleeve-lock sockets connect by sliding back the sleeve on the socket, inserting the plug, and releasing the sleeve. To disconnect, slide the sleeve back and pull out the plug.

Push-to-connect sockets are easier to connect than sleeve-lock sockets. Connect by pushing the plug into the socket until you hear a click. To disconnect, slide the sleeve on the socket forward until the plug ejects.

Pioneer × ISO Minimal-Spill couplings let you adapt between different quick-disconnect styles. ISO Minimal-Spill quick-disconnect couplings are also known as ISO 16028 couplings.

Chrome-plated steel has a bright, shiny appearance.

Plugs and sockets with a gasket offer extra protection against leaks.

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.
