What are KF Vacuum Flanges?
Vacuum flanges are semi-permanent connections to join together parts of a vacuum system.
Several vacuum flange standards exist, and the same flange types are called by different names by different manufacturers and standards.
Klein Flange (KF) or Quick Flange (QF), also known as DN, NW, Pneurop and Kwik-Flange are characterized by their ability to be seal with centering rings and clamps instead of requiring bolts.
Blank Flanges have no through-hole.
