Add a push-to-connect junction to unthreaded ports for easy connections with tubing. To install, drill a stepped hole in your surface, push the fitting components into place, and insert your tubing.

Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

Couplings allow for maximum flow because there's no shut-off valve in the plug or the socket. Compatible with Open-Flow-shape plugs and sockets.

Compatible with Japanese-shape plugs and sockets.

Also known as dry disconnects and double shut-off couplings, these have a shut-off valve in the plug and socket for minimal fluid loss when disconnecting the hose line.

Use these couplings at pressures up to 10,000 psi. The plug and socket thread together to form a stronger connection than other quick-disconnect couplings. They are compatible with High-Pressure Thread-Lock-shape plugs and sockets.

Use these couplings at pressures up to 5,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with International Standard ISO A-shape plugs and sockets.

Ideal for lines with rapid changes in pressure and flow, these couplings have threads that lock them together. They connect more securely than push-to-connect couplings, whose bearings wear out in high-impulse conditions.

Use these couplings at pressures up to 10,000 psi. Also known as flush-face couplings, the plugs and sockets have a flat face, which allows them to mate close together, reducing fluid loss when connecting and disconnecting the line. They are compatible with High-Pressure Minimal-Spill-shape plugs and sockets.

Use these couplings at pressures up to 6,500 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Snap-Tite H-Shape plugs and sockets.

Couplings are metal, which has better durability than plastic cam-and-groove hose couplings. They consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. To connect, insert the plug into the socket and push the levers down.

Made of polypropylene, these couplings are lighter in weight than metal cam-and-groove couplings. Also known as dry disconnects and double shut-off couplings, they have a shut-off valve in the plug and the socket for minimal fluid loss when disconnecting your hose line.

To minimize fluid loss when connecting and disconnecting your line, these couplings have flat faces for a close fit and shut-off valves to stop the flow—they meet ISO 16028, which is an international standard for hose couplings.

Minimize chemical and petroleum spills during accidental disconnects, such as a driver pulling away during loading. These couplings have a shut-off valve on each half to stop flow when they’re separated.
