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’re often used in applications such as vacuum coating and heat treating, leak testing, and analyzing gases. The three-piece bolted body comes apart for inline replacement of internal components. Body is 316 stainless steel for excellent corrosion resistance. The lockable lever handle can be fixed in place using a padlock (not included). Valves are full port, so they do not restrict flow.

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. Valves gradually open and close with multiple turns of the wheel handle to prevent system damage from suddenly starting and stopping flow. They connect to another quick-clamp fitting with a clamp and a ring (sold separately). All have a nonrising stem that stays in the same position whether the valve is open or closed. Body is 304 stainless steel for good corrosion resistance.

Use these rings with quick-clamp high-vacuum fittings. They consist of a stainless steel inner ring covered by a fluoroelastomer O-ring.
Rings with screen have a stainless steel screen to filter out large particles.
Pressure-rated rings have an aluminum outer ring to withstand extra pressure.
