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

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

A 316 stainless steel body gives these fittings the best corrosion resistance of all our metal push-to-connect tube fittings.

Designed for use in welding applications, these fittings are flame retardant.

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.

Made of acetal, these compression fittings are lighter in weight than metal compression fittings and won’t absorb moisture when used in wet environments.

Safe for use in your air brake line, these fittings meet Department of Transportation FMVSS 571 standards. They’ve been tested for thermal cycling, vibration, and burst pressure, so put them to work right away.

Made of brass, these fittings resist corrosion from water and are more durable than plastic and aluminum fittings.

Minimize leaks in your line—these fittings have a single barb that creates a smooth clamping surface for extra-tight connections.

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.

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.

Create custom couplings to save space and snake around obstructions. These couplings let you swap in different ends to change the connection size, type, and orientation to fit your specific setup.

Made of plastic, these couplings are lighter in weight than metal luer lock couplings. They're a popular choice in labs because of their versatility—they fit any other luer lock plug, socket, syringe, or needle.

Also known as instant fittings, these chemical-resistant plastic fittings connect to tubing with a push. An internal gripping ring holds the tubing tight.

These plastic compression fittings meet NSF/ANSI Standard 51 for food contact.

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

These fittings keep their strength in moist environments and meet NSF/ANSI 61 for drinking water. Also known as instant fittings.

Use these fittings at pressures up to 9,700 psi. Also known as instrumentation fittings, they are made to tight tolerances for use in high-precision applications. They are compatible with Swagelok®, Let-Lok, and Parker A-Lok fittings.

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

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

Transfer liquids and gases into high-vacuum chambers with these assembled fittings, also known as feedthroughs. Their quick-clamp (ISO-KF) connections are easier to install and remove than bolt-on flanges.

The threads on the tube end of these fittings are Class 3A or 3B and adhere to tighter tolerances than other 37° flared fittings.

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.

A nut with two sleeves (ferrules) gives these fittings extra gripping power. The sleeves bite into tubing as you tighten the nut, creating a strong seal.

Also known as instrumentation fittings, these are made to tighter tolerances than standard compression fittings. They are compatible with Parker CPI fittings.

Also known as JIC (Joint Industrial Council) fittings, these provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

Connect these fittings to Schedule 40 plastic pipe—they are the industry standard for residential and commercial low-pressure plumbing and water supply applications. They are plastic for good corrosion resistance.
