Use these rings with quick-clamp high-vacuum fittings.

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.

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.

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

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

A braided exterior protects this hose from abrasion and over-bending. Also known as bellows, the ribbed interior makes it flexible enough to connect high-vacuum components that aren't directly aligned.

Also known as vacuum isolation valves, these block flow so you can install and remove gauges from your system. They can also be used to add or vent gases in high-vacuum systems.

Achieve powerful vacuum and continuous flow for applications such as vacuum drying, solvent evaporation, and distillation.

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.

Purify exhaust fumes while silencing the noise from your oil-free high-vacuum pumps.

Clamp these exhaust filters onto oil-sealed, high-vacuum pumps to remove oil, smoke, and other contaminants and keep workplace air clean. Once captured, the oil returns to the pump to be reused.

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.

Also known as Torr Seal, this sealant forms a rigid bond that seals leaks on vacuum systems or components.

Cleaned and double bagged in an ISO Class 5 (Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.
