Features

The typical KF (QF, NW, Kwik, or ISO-K) Flanges assembly consists of two idenƟcal flanges, a center-ring, and aluminum clamps with a wingnut fastener frequently connect and disconnect without tools. The vacuum seal is affected by uniform applicaƟon of pressure by the clamp on 15º surface of the flange. The maƟng flange surfaces compress an O-ring (held in place by metal centering ring) to generate a seal.
