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.

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

Connect quick-clamp fittings in high-vacuum applications.

Create access points in ultra-high-vacuum lines or chambers by bolting two same-size flanges together with a copper gasket between them. The flanges’ sharp edges dig into the copper gasket and form an extremely tight seal, which means they handle higher vacuum pressures than other high-vacuum fittings with rubber gaskets.

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.

For high-vacuum systems with tube sizes too large for quick-clamp (KF) fittings, choose these bolt-together fittings.

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

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

An alternative to bolt-together fittings, these handle larger tube OD sizes and have higher vacuum ratings than quick-clamp fittings. Also known as ISO-K high-vacuum fittings, the clamps have claws that grab hold of fittings with flanged ends.

Repair multiple pinholes, punctures, splits, and full-circle breaks on air and water lines with these clamps. They slide over tubing, so there’s no need to disassemble your system.

Made of stainless steel, these fittings have better corrosion resistance than brass fittings.

Color-code fittings for easy identification. These aluminum fittings have good corrosion resistance, but are lighter in weight than brass.

The nickel plating on these fittings provides better corrosion resistance than unplated brass fittings.

An all-metal body and built-in tube support allow these fittings to handle pressures up to 800 psi—the highest pressure rating of all our push-to-connect tube fittings.

A built-in shut-off valve stops airflow when the fittings are disconnected from tubing.

Designed for use in welding applications, these fittings are flame retardant.

Use at pressures up to 250 psi.

Made entirely of nickel-plated brass, these fittings have better corrosion resistance than unplated brass fittings.

Couplings have an identical claw-style head that connects to another twist-claw hose coupling with a quarter twist.

Also known as Thor couplings, these have two locking points to give you twice the gripping power of standard grip-lock couplings. They consist of a plug and a socket that connect with a quarter twist.

The industry standard for quick-disconnect couplings, these are also known as industrial interchange couplings. Compatible with Industrial-shape plugs and sockets.

Compatible with ARO-shape plugs and sockets.

Compatible with Schrader-shape plugs and sockets.

Metal hose fittings have better durability than plastic barbed hose fittings.

Fittings have sharp barbs that grip push-on hose with no clamps or ferrules required. The more you pull on the fittings, the tighter the hose will grip. Use in low-pressure hydraulic applications up to 350 psi.

Low-profile barbs and a longer first barb allow for a smoother, easier installation than other barbed fittings. Slide the barbed end into hose and secure with a clamp.

Couplings consist of a plug and a socket that connect quickly. Use them if you need frequent access to a line. They are designed for low-pressure steam applications up to 300 psi.

Use these couplings at pressures up to 3,000 psi. They consist of a plug and socket that connect and disconnect quickly. Use them if you need frequent access to a line. They are compatible with Pioneer-shape plugs and sockets.

These manifolds have two separate sections inside, so you can run two different substances through them without worrying about them intermixing. Also known as headers.

Use these junction blocks to organize and separate multiple lines in your system. They have threaded holes that allow air or fluid to flow straight through the block.

These connectors are for use in low-pressure air and vacuum conveying systems, as well as in gravity-flow systems.

These junction blocks have threaded holes that allow air or fluid to flow at a 90° angle through the block. Use them to organize and separate multiple lines in your system.

Designed for ultra-clean environments, these manifolds are cleaned, dried, and vacuum sealed in plastic to prevent dirt and moisture from contaminating the inside. Use them to distribute air or fluid to multiple locations from a single supply source. Also known as headers.
