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

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.

Withstanding up to 300° F, these fittings have the highest temperature rating of all our brass push-to-connect tube fittings for air and water.

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.

Lighter in weight than their metal counterparts, these quick-disconnect couplings are made of acetal plastic. They are moisture resistant, so they won’t absorb water and lose strength, even in high-humidity environments.

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.

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.

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.

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

Fittings can withstand temperatures up to 200° F.

Also known as instant fittings, these connect to tubing with a push, and an internal gripping ring and O-ring hold the tubing tight. Use in applications up to 150 psi.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 150 psi.

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

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.

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

A PTFE seal on the tube end of these fittings allows for an extra-strong connection in high-vibration applications.

Bolt these fittings onto your ultra-high-vacuum chamber to transfer liquids and gases inside. Also known as feedthroughs, they come assembled with a flanged (CF) fitting, metal tubing, and two Yor-Lok tube fittings.

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.

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

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.
