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

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

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.

Pair these nuts with vibration-resistant compression sleeves and fittings for 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.

Polished to a 15 Ra and under finish, these fittings have a mirror smooth interior. They are also known as ultra-high-purity fittings.

Fittings have two anti-torque rings that compress the gasket to prevent rotation and reduce particle generation in high-vibration applications.

Also known as luer lock couplings, these consist of a plug and socket that connect with a half turn. Use in low-pressure applications up to 30 psi.

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.

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

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.

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.

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—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.

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

The external hex bolt on these fittings allows for easy installation in cramped spaces.

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.

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°.

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.

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

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.

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.

Use these to replace a damaged sleeve (ferrule) in quick-assembly compression nuts.

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 have a built-in sleeve (ferrule), so the sleeve is positioned correctly for installation.

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.

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

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.

Quick-disconnect couplings consist of a plug and a socket that join with a latch so you can easily connect and disconnect your line. Use in applications up to 150 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.
