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.

Butt-weld fittings allow for a smooth, flush connection that provides maximum flow.

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

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.

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

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 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.

Create airtight seals in high-vacuum systems by placing these rings between two claw-clamp (ISO-K) or bolt-together (ISO-F) fittings.

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

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.

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

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.

Use these barbed fittings in low-pressure steam applications up to 150 psi. Slide the barbed end into hose and secure with a clamp.

Compatible with ARO-shape plugs and sockets.

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

Compatible with Schrader-shape plugs and sockets.
