Connect quick-clamp fittings in high-vacuum applications.

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.

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.

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

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 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.

Add a window to your high-vacuum system. With a pane of borosilicate glass sealed inside a high-vacuum CF flange, these sights bolt onto vacuum chambers, tee fittings, and manifolds.

Designed with quick-clamp (KF) connections, these sights connect to a port on a high-vacuum chamber, so you can monitor what's happening inside.

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.

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

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.

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.

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