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.

Save time installing sleeves and nuts—these sets come oriented in the correct direction and order on a dispenser.

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

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

The flat face of the fitting connects to a tube adapter so you can slide the tubing and fitting sideways to disconnect in cramped spaces. They are also known zero-clearance fittings.

Use at pressures up to 4,300 psi.

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

Solder these fittings to tubing for a permanent, leak-tight connection. They are also known as sweat fittings.

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

Create a strong seal on copper tubing when you couple these nuts with compression sleeves and fittings.

These fittings include a nut with a built-in sleeve, so there’s no need to remove the nut for assembly.

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.

Also known as JIC (Joint Industrial Council) fittings, these connect to tubing that is flared to 37°. They can handle higher pressures than 45° flared 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.

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

Also known as JIS (Japanese Industrial Standard) fittings.

With the best corrosion resistance of any metal fitting we offer, these Hastelloy fittings will stand up to aggressive chemicals and are resistant to pitting and stress cracking. Also known as instrumentation fittings, they include a nut with two sleeves.

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.

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.

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.

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.

A built-in tube support slips inside the tubing to prevent collapsing and provides a sturdy connection for an extra-tight seal.

Use these luer lock couplings to quickly connect low-pressure air and water lines. Made of stainless steel, they’re more durable than plastic couplings.

Use these corrosion-resistant fittings in a low-pressure pipe line.

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.

Socket-connect fittings are easier to weld than butt-weld fittings because the fitting doesn't need to align perfectly to the pipe. Slip the pipe into the socket and weld.

Use these unions to connect different metals in a piping or plumbing system. They have a gasket with a plastic sleeve that inhibits destructive corrosion.

For use in noncorrosive environments, these fittings have better strength than our low-pressure iron and steel pipe fittings.

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

Use these fittings for low-pressure applications in noncorrosive environments.

Crimp these fittings onto steel pipe to form a tightly sealed connection that’s faster than threading or welding and doesn’t require heat.

Use these heavy-duty brass fittings for high-pressure drinking water applications.

Use these fittings in low-pressure flow applications. They have good corrosion resistance.

Choose these fittings when you need better strength than our low-pressure brass and bronze pipe fittings.

In addition to being lightweight, these aluminum fittings offer good corrosion resistance. Use them in low-pressure flow applications.
