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.

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

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.

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

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

Connect to high-vacuum pumps to route exhaust fumes out of your work area. Also known as roughing hose.

To create a tight seal in vacuum conditions higher than 29.9” Hg, these valves have ultra-high-vacuum tube fitting connections, which are also known as KF, QF, and NW fittings. They are often used in applications such as vacuum coating and heat treating, leak testing, and analyzing gases.

Use these pumps in applications such as degassing and servicing refrigeration and freezer systems.

Achieve vacuum levels up to 1 x 10 ^-12 torr with these ultra-high-vacuum pumps.

Illuminate the interior of your high-vacuum chamber to clearly observe what’s inside.

Install these filters between your high-vacuum chamber and the inlet of your pump to remove dust, water vapor, and other contaminants from the system and protect the pump. Commonly used in vacuum-furnace and coating applications, they have a polyester filter element that traps particles as small as 5 microns.

To keep airborne oil and odor out of your work environment, connect these filters to your high-vacuum oil pump. They purify pump exhaust in two stages: a fiberglass layer captures oil and collects it into a drain, and an active carbon layer removes any odor-causing oil or chemical vapors.

These O-rings are heat-treated, cleaned, and double-bagged in an ISO Class 5 (Class 100) clean room for use in high-vacuum systems.

Coat knobs, handles, mirrors, and other objects with a micron-thin, decorative finish. 99.999% or 99.88% elementally pure, these metals vaporize when heated with low-voltage current inside a high-vacuum environment.

Fasten these screws inside a high-vacuum system without bringing in contaminants.
