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

Made of brass, these fittings have good corrosion resistance.

These fittings won’t absorb moisture, so they’re good for water and high-humidity air applications.

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.

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 couplings are more durable than plastic couplings.

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.

Prevent mixing the wrong high-pressure lines—these couplings are designed to only connect with a plug or socket of the same color.

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

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

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.

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

A single sleeve (ferrule) compresses the tubing as you tighten the nut on these fittings, creating a strong seal. They are brass for good corrosion resistance.

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.

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

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

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.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

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°.

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

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.

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.

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.

Crimp these fittings to copper tubing with a crimping tool for a leak-tight connection that doesn’t require heat or soldering. They are comparable to Viega ProPress fittings.

These fittings have two sleeves for extra gripping power. They bite into steel tubing as you tighten the nut to form a strong seal.

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.
