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

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

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.

Tighten these nuts onto high-pressure compression sleeves 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.

Instead of a metal sleeve (ferrule), these fittings have a rubber sleeve that cushions tubing and absorbs vibration to maintain a tight seal, even when connected to large pumps.

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.

For applications that require an extra level of cleanliness, these fittings are individually bagged to prevent contamination.

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.

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°.

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

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.

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

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°.

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.

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

Use these sleeves with brass compression nuts and fittings to create a seal on plastic and rubber tubing.

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.

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

Use these nuts with plastic compression fittings to create a seal on plastic tubing. They're moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

Couplings can handle pressures up to 250 psi.

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

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

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