KF Clamp

vacuum fittings follow ISO-KF standards,they are commonly used to build foreline vacuum plumbing and process systems. They are often called quick flange fittings because they are quick to assemble. A circumferential clamp and centering ring form the vacuum seal between the connecting flanges. The centering ring contains a rubber elastomer o-ring. The standard sizes for quick flange fittings are KF-10, KF-16, KF-25, KF-40, and KF-50 with flange sizes NW-10, NW-16, NW-25, NW-40, and NW-50, respectively. They are made of Aluminum SS304 SS316.

KF Flange series KF blank flange

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 mating flange surfaces compress an O’ring to generate a seal. ＊The vacuum seal is effected by uniform application of pressure by the clamp on 15º surface of the flange.
