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.

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.

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.
