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

When used with high-pressure compression fittings and nuts, these sleeves bite into stainless steel tubing to form a strong seal.

Use these nuts with compression sleeves and fittings to create a strong seal on stainless steel tubing.

Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing.

Couple these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on stainless steel tubing.

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

Use with soft plastic tubing to prevent the tube from collapsing.

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

Individually bagged to prevent contamination, these fittings are suitable for applications that require a high level of cleanliness.

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°.

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

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.

With a nickel-plated finish, these compression fittings resist corrosion better than plain brass fittings.

Create a strong connection without heating, flaring, or soldering.

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

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.

Use these sleeves with Yor-Lok nuts and fittings to create an extra-strong seal on copper tubing.

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.

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.

Use these sleeves with compression nuts and fittings, sometimes called bite fittings, to create a strong seal on steel tubing. They are also known as ferrules.

Use these sleeves with a nut and fitting to provide a tight metal-to-metal seal on steel tubing that is flared to 37°.

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

Use these sleeves—also known as ferrules—with high-pressure compression nuts and fittings. They withstand about twice as much pressure as sleeves for standard compression fittings, so they’re good for hydraulic power applications.

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as standard compression fittings, so they’re good for hydraulic power applications.

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.

These Monel fittings have the corrosion resistance to handle hydrofluoric and sulfuric acid. Also known as instrumentation fittings, they include a nut with two sleeves.

The external hex bolt on these fittings allows for easy installation in cramped spaces. They are also known as banjo-style fittings and JIC (Joint Industrial Council) fittings. They provide a tight seal on tubing that is flared to 37°.

Tube supports slip inside tubing to prevent the walls from collapsing.

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.

Use these O-rings with brass compression tube fittings that have BSPP male threads. They create a seal on the BSPP male threads to guard against leaks.

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.

Tube supports slip inside tubing to prevent the walls from collapsing.

Tube supports slip inside tubing to prevent the walls from collapsing.

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

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.

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.

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

Tube supports slip inside tubing to prevent the walls from collapsing.

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

Use these nuts with high-temperature compression fittings for food and beverage to create a seal on plastic tubing.

Use in medium-pressure applications up to 230 psi.

These Schedule 40 fittings are the industry standard for gravity-flow drain, waste, and vent (DWV) applications.

Bolt two same-size flanges together with a gasket to create an access point within a line. Flanges are an economical option for gravity-flow chemical waste systems. They are ABS plastic, which has excellent strength and impact resistance and good chemical resistance.
