The KF/ISO system of vacuum components is the family of specialty flanges, elbows, tees, crosses, bellows, etc. having interface dimensions defined by the International Standards Organization. The flanges are secured by a clamp acting on the outer flange surface. The ISO sequence goes to 20” (500mm). The maximum tubing size in the KF sequence is 2” (50mm) The letters KF often used in describing the system denote the “small” series. KF is derived from “Kleinflansch”, German for “small flange”.

The KF/ISO System in the USA

HIS presently supplies the ISO metric flanges with inch dimensioned stubs and sockets. HIS manufactures its KF/ISO products at its manufacturing facility in Hillsboro, Oregon.
