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.

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.

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.

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

Often used in outdoor, damp, and washdown environments, these 316 stainless steel fittings will not corrode from water, salt, or chemicals. The male threaded ends mate with NPT, NPTF, BSPT, BSPP, and other universal threads, so you won’t have to worry about matching exact threads when you’re on the job.

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

These metal hose fittings have better durability than plastic barbed hose fittings. They are 316 stainless steel for excellent corrosion and chemical resistance. Slide the barbed end into hose and secure with a clamp.

These couplings have a lower profile than other claw-style couplings to fit in cramped spaces. They consist of a plug and a socket that connect with a quarter twist. Also known as Bowes couplings.

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

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

Use these couplings at pressures up to 5,000 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 International Standard ISO B-shape plugs and sockets.
