HFS KF/NW vacuum fittings are made from 304 stainless steel and come with a high polish finish. These fitting use a circular joint with a centering ring, gasket, and clamp to create an air-tight seal. They are available in multiple sizes from KF-10 to KF-50.

Please note these fittings are not compatible with tri-clamp fittings, and use of an adapter will be necessary to connect them.
