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

The sleeve in these fittings is rubber instead of metal, so it cushions the tubing and absorbs vibration while creating a tight seal.

The flared end of the fitting nests inside the fitting body, providing extra support to the tubing. Fittings are also known as inverted 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.

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

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

The thick walls of these fittings can withstand more than twice the pressure of standard compression fittings.

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.

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

The male pipe threads on these fittings have a sealant applied for extra protection against leaks.

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

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

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 these nuts with compression sleeves and fittings, also known as bite fittings, to create a strong seal on steel tubing.

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.

A tube adapter sits flush against the flat face of the fitting so you can slide the steel tubing and fitting sideways to disconnect in cramped spaces. Also known as zero-clearance fittings.

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

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.

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 plastic and rubber tubing to guard against leaks.

These compression tube fittings meet Department of Transportation FMVSS 571 safety standards for air brake lines.

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

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

Lighter in weight than their metal counterparts, these compression fittings are polypropylene.

Couplings can handle pressures up to 250 psi.

Made of brass, these couplings are more durable than plastic couplings.

These brass fittings meet NSF/ANSI 372 for drinking water. They include a nut with a built-in sleeve (ferrule), so there’s no need to remove the nut for assembly.

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