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.

Made of plastic, these sleeves create a strong seal without damaging tubing.

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

Use these nuts with compression sleeves 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.

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

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.

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

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

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

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.

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

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—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 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.

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.

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

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

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're moisture-resistant acetal, so they won't absorb water and soften, even in high-humidity environments.

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.

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.

Lighter in weight than metal quick-disconnect couplings, these couplings are plastic.

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.

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

Use these nuts with brass compression fittings to create a seal on plastic tubing. They meet NSF/ANSI 372 for use with drinking water.
