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

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

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

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

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.

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.

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.

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

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.

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

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

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.

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

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

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 with a nut and fitting to provide a tight metal-to-metal seal on steel 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.

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

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

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

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

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.

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

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

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

Couplings can handle pressures up to 250 psi.

Made of PVDF (also known as Kynar), these fittings have excellent strength and can handle temperatures as high as 240° F or 270° F.

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

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

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.
