KF Flange Series

The Small flange or KF standard (DIN 28403, ISO 2961) is the standard connection for vacuum pipes up to the nominal diameter of DN50 used in low, fine and high vacuum.
A seal is positioned between the flanges. The seal consists of a centering ring and the O-ring stretched upon. The flanges are held together by a clamp. The clamp has an inclined interior surface adequate to the conical outer surface of the flanges.
Usually centering rings and standard clamps are used with wing nuts. They enable a quick and easy assembly without any tools. Trapped centering rings and special clamps or clamp chains are offered for special applications.
Claw clamps or so-called bulkhead clamps are available for wall mounting.
