Kits contain Industrial quick-disconnect plugs in four coupling sizes so you can determine the size of your couplings without needing to measure.

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

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

Compatible with Lincoln-shape plugs and sockets.

A slim body allows these couplings to fit into tight spaces. Compatible with Compact-shape plugs and sockets.

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

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

Connect air brake lines with fittings that won’t crack in sub-zero temperatures. They meet Department of Transportation FMVSS 571 safety standards, so they’re often used in commercial trucks and trailers.

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.

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

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

Fittings have good corrosion resistance.

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.

Quickly connect low-pressure air lines with these luer lock couplings. Made of brass, they are stronger and more durable than plastic tube couplings.

To prevent contamination, these couplings are cleaned, double bagged, and packaged in a clean room. Known for their versatility, they fit any luer lock plug, socket, syringe, or needle.

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

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

Quickly connect low-pressure stainless steel lines with these couplings. Made of 316 stainless steel, they have excellent corrosion resistance.

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

No sleeve is required to assemble these fittings, which makes for a faster, more convenient installation compared to 37° flared fittings. They are also known as refrigeration and SAE fittings.

Not only do these brass fittings have the strength to handle high-pressure applications, the male threads have a sealant applied for extra protection against leaks.

Used in low-pressure pipe lines, these brass fittings have a plating that makes them shiny and improves corrosion resistance.

The male threads on these brass fittings have a sealant applied for extra protection against leaks. Also known as Pressure Class 125 fittings, they are built for use in low-pressure applications.

When you're unsure of the exact thread type you need, these fittings have universal threads that are compatible with the most common ones (NPT, NPTF, BSPP, BSPT).

Also known as instrumentation fittings, these have the most precise threads and the tightest tolerances of all the brass pipe fittings we offer.

The male threads on these fittings have a sealant applied for extra leak protection.

To prevent leaks in low-pressure lines, the male threads on these fittings have an acrylic sealant already applied for extra protection.

These fittings are strong enough to handle extreme pressures, yet small enough to fit into cramped spaces.

The strongest steel fittings we offer, these can withstand extreme-pressure applications.

These fittings can stand up to high-pressure applications. Use them in noncorrosive environments.

A galvanized finish gives these fittings fair corrosion resistance. They have the strength to handle medium-pressure applications.

Unlike other stainless steel fittings, these are made in the U.S.A. for superior quality. As another marker of quality, they come with a certificate with a traceable lot number and test report that guarantees material composition.

The male threads on these fittings have a sealant applied for extra leak protection.

Choose these fittings when you want the same high-quality found in our low-pressure pipe fittings, but need more strength to handle higher pressures.

Also known as Pressure Class 3000 fittings, these have the highest pressure rating of all the aluminum pipe fittings we offer.

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.

Penetrate tight pipe junctures with the most flexible expansion plugs we offer.

Often used for plumbing tests, these plugs thread into tees and inflate to block flow across the pipe.

Use the bypass tube on these plugs to add air, water, and other fluid to your pipeline or to relieve back pressure while testing.
