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.

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.

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.

Add a window to your high-vacuum system. With a pane of 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.

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

Hold and heat coating material to extremely high temperatures for use in high-vacuum thin film coating processes. Also known as physical vapor deposition (PVD), thin film coating creates micron-thin, consistently smooth finishes on knobs, mirrors, and other objects.

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.

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.

A firm consistency and resistance to evaporation make this grease ideal for vacuum applications, such as flow meters, vacuum and pressure systems, and laboratory equipment.
