An all-metal body and built-in tube support or dual seals allow these fittings to handle the highest pressure ratings of all our push-to-connect tube fittings.

Aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

Fittings have good corrosion resistance.

Made of brass, these couplings are more durable than plastic couplings.

With no latch, these couplings have a compact design to fit in small spaces. They can handle pressures up to 700 psi.

Made of brass, these fittings withstand frequent washdowns in food-processing applications. They also adhere to NSF/ANSI safety standards, so they’re safe to use with food, beverages, and dairy.

These quick-disconnect couplings mate with a sanitary stainless steel quick-clamp fitting for use in dairy lines.

Fittings are 316 stainless steel, which has excellent chemical resistance and is more durable than plastic.

Tube supports slip inside tubing to prevent the walls from collapsing.

Create a push-to-connect junction in equipment with these fittings. To install, drill a stepped hole in your surface, push the fitting components into place, then insert your tubing.

Connect stainless steel tubing on one end and plastic tubing on the other end.

Choose these metal fittings when you need better durability than our plastic push-to-connect fittings.

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.

Made of nylon, these fittings are lighter in weight than metal barbed hose fittings.They have sharper barbs than standard barbed hose fittings to grip push-on hose without the need for clamps or ferrules. The more you pull on the fittings, the tighter the hose will grip.

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Sockets accommodate five common plug shapes: Industrial, ARO, Lincoln, Tru-Flate, and European.

Compatible with ARO-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.

Plugs and sockets are color coded by shape so you can't mix hose lines. Only plugs and sockets of the same color will fit together.

Compatible with Japanese-shape plugs and sockets.

Larger, heavier, and rated for pressures up to 10,000 psi, these couplings maximize flow in high-pressure washing applications, such as water blasting.

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.

Couplings consist of a plug and a socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are designed for coolant applications up to 200 psi. Also known as coolant-line mold couplings.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

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 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.

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.

Add quick connection points for mechanical gauges and other diagnostic equipment to your line. These couplings are also known as test ports and diagnostic couplings.

Made of brass with a steel wing nut, these couplings are tough enough to handle occasional drops to concrete and frequent connections on dump truck, oil rigs, and other heavy duty equipment. Compared to push-to-connect couplings, these are threaded, so they're easier to connect when there's pressure in your line.

Couplings are compatible with quick-disconnect Plastic-shape plugs and sockets. They are designed for food and beverage applications and won’t impart tastes or odors to the product. They consist of a plug and a socket that connect and disconnect quickly so you can frequently access your line. Use at pressures up to 100 psi.

Couplings consist of a plug and a socket that connect more quickly than threaded garden hose couplings. To connect, push the plug into the socket. The compact design makes these couplings sleeker and easier to handle than cam-and-groove garden hose couplings.

Use these couplings when you need frequent access to a gas line. A complete coupling consists of a plug and a socket that connect and disconnect quickly.

Twist these fittings onto aluminum pipe for quick, sealed connections—no threading, soldering, or welding necessary. Use them to build a compressed air system in half the time it would take to build a copper or steel system.

Valves have a plastic body.

Insert tubing into the push-to-connect fittings on these valves—no heat, solder, or flux required. They meet NSF/ANSI 51 for safe use with food.

For a lightweight and economical alternative to metal, these valves are made of plastic. Insert tubing into the fittings—no heat, solder, or flux required. All meet NSF/ANSI 61 for use in drinking water systems.
