A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Make lightweight connections without the hassle of matching the exact thread type—these fittings connect to NPT, NPTF, BSPP, BSPT, and other universal threads.

Made of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

The threads on these fittings mate with NPT, NPTF, BSPT, and BSPP threads.

Connect high-pressure brake lines with fittings that won’t crack in frigid temperatures. Often used on commercial trucks and trailers, these fittings meet Department of Transportation FMVSS 571 safety standards.

Ball bearings allow these fittings to rotate 360°, even after they are tightened. They have a special seal that reduces friction to allow for continuous rotation.

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.

You don't need a clamp to secure these fittings to tubing. They have a nut on the barbed end that tightens to hold the tubing in place.

Not only are these chrome-plated brass couplings corrosion resistant, they’re also durable enough to handle pressures up to 250 psi and can be used with vacuum.

A built-in shut-off valve stops the flow when you separate these couplings, so air or water won’t leak from your line. Made of nylon, these couplings are lightweight and have good impact and abrasion resistance.

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

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 61 for use with drinking water.

These quick-disconnect couplings meet NSF/ANSI 169 for food equipment.

Also known as instant fittings, they connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 140 psi.

Connect quick-clamp fittings in high-vacuum applications.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

An alternative to bolt-together fittings, these fittings handle larger tube OD sizes than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

A single sleeve (ferrule) bites into tubing as you tighten the nut, creating a strong seal. The nut and sleeve are included.

Polished to at least a 15 Ra finish on the inside, these fittings have an ultra-smooth interior surface that helps prevent contamination. They are also known as ultra-high-purity fittings.

Bolt two same-size flanges together with a gasket to create an access point within a line. They are also known as Pressure Class 150 flanges. They have thick, strong walls to handle heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

See what’s flowing through your line with this clear pipe. Since it’s Schedule 80, this pipe has thicker, stronger walls than standard-wall pipe, so you can use it for heavy duty industrial plumbing and water supply applications, such as water processing, waste water treatment, and irrigation.

Connect to CPVC pipe fittings for use in high-temperature plumbing and water supply applications up to 170° or 200° F.

Eliminate sharp bends at the end of your air and water hose—these fittings have a built-in kink absorber.

Also known as automotive couplings. Compatible with Tru-Flate-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.

Made of acetal, these couplings are lighter in weight than metal quick-disconnect couplings. Compatible with Plastic-shape plugs and sockets.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

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.

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.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Also known as ground-joint couplings and boss couplings, these fittings are designed for high-pressure steam applications up to 600 psi. Insert the barbed end of the fitting into hose, then position the interlocking clamp over the hose and bolt into place. The clamp firmly grips your hose as it locks into the ring of the barbed end, creating a leak-tight seal.

Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.
