Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

Use these heavy duty, corrosion-resistant fittings in high-pressure flow applications.

Use these fittings in extreme-pressure conditions up to 15,000 psi.

When space is at a premium choose these compact fittings.

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

The galvanized finish on these fittings provides fair corrosion resistance. Fittings are for use in low-pressure applications.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

The heavy duty caps and plugs in these assortments come in various sizes and stand up to high-pressure flow applications. Made of steel, they’re for use in noncorrosive environments.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

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

Compatible with ARO-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

Compatible with Ring-Lock-shape plugs and sockets.

With an unobstructed air path, these couplings have better airflow than other coupling shapes of the same size. Compatible with European-shape plugs and sockets.

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.

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 3,000 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 Pioneer-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 B-shape plugs and sockets.

Use these couplings at pressures up to 7,200 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 International Standard ISO Minimal-Spill-shape plugs and sockets.

Reduce the risk of spills near electronics when connecting and disconnecting liquid cooling lines. Also known as double shut-off couplings, these couplings have a shut-off valve on both sides that stops the flow of coolant if they’re separated.

Also known as dry disconnects and double shut-off couplings, these couplings make connecting and disconnecting your line quick and virtually spill-free. Built to stand up to petroleum products, such as diesel fuel and gasoline, their body and gasket are made from materials that won’t corrode from oil.

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.
