KF (also referred to as NW) assemblies consist of two Flanges, a Center-Ring and an aluminum Clamp. Clamps are assembled with wing nuts to insure ease of use over time without tools. A uniform application of pressure on the clamp insures a vacuum seal. The mating flange surfaces compress the O-Ring, which is held in place by a metal centering ring, to generate the vacuum seal.
