The typical KF or NW assembly consists of two identical flanges, a center-ring, and an aluminum clamp with a wingnut fastener frequently connect and disconnect without tools.
The vacuum seal is effected by uniform application of pressure by the clamp on 15o surface of the flange.
The mating flange surfaces compress an O’ring (held in place by metal centering ring) to generate a seal.
