Use at pressures up to 1,500 psi.

Use these fittings at pressures up to 9,000 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.

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.

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.

Pair these nuts with vibration-resistant compression sleeves and fittings for a strong seal on stainless steel tubing.

Connect quick-clamp sanitary tube fittings—also known as aseptic fittings—for a fast and easy way to access your line.

Also known as I-line fittings, the flanged end of the male adapter on these high-polish fittings interlocks with the flanged end of the female adapter to provide extra support to your line.

Also known as KF, QF, and NW fittings, these fittings are for high-vacuum applications, such as vacuum coating and heat treating, leak testing, and analyzing gases.

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°.

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.

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.

If the tubes in your system are too large for quick-clamp fittings, use these bolt-together fittings. Also known as aseptic fittings, they’re 3-A certified for sanitary standards because their smooth inner finish makes it easy to remove residue.

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.

Twist these fittings onto high-vacuum tubing to quickly make sealed, high-vacuum connections without the need for clamping, welding, or tools.

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

Also known as feedthroughs, these fittings transfer liquids, cryogenic liquids, or gasses into high-vacuum chambers for coating, cooling, and leak-testing applications without losing vacuum pressure.

Connect claw-clamp high-vacuum fittings for an airtight seal.

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

Thicker walls make these fittings—sometimes called flareless or bite fittings—withstand about twice as much pressure as 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.

Use these fittings in an air vacuum system to avoid the hassle of brazing and welding. Insert two fittings into a clamp and tighten to form a secure seal in steel tubing.

Repair pinholes, punctures, and cracks in low-pressure systems with these clamps. Insert tubing into the clamp and tighten the bolts to create a secure seal.

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

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.

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

When cleanliness is crucial to your application, choose these fittings that are individually cleaned and bagged to prevent contamination.
