KF (QF) Flanges and Fittings Standard Dimensions and Definition
KF (QF) Flanges. KF flanges are a sexless design made from 304 stainless. Also known as ISO, DIN, Pneurop, Quick Flange, Klein Flange, Dell Flange and Kwik-Flange.
The seal is a rubber/ elastomeric o-ring mounted in a centering ring, which aligns the flanges and holds the o-ring in position.
A clamp is used to compress o-ring and secure a leak tight seal.
Parts are helium leak tested to 1 x10-10 cc/sec for quality assurance.
