ISO-F Collar Flange with Retaining Ring - St St DN 400 ISO-F

Components and Fittings ISO-K ISO-F

The small flange connection developed by Leybold has become the basis of the international standard for vacuum technology.

With the appropriate collar flanges, the clamp flange can be connected to various fixed bolted flange systems (ISO-F, DIN EN 1092-1, etc.) see figures in chapter “ISO-F and DIN EN 1092-1 Fixed Flange Fittings”.The clamp flange connection (to DIN 28 404 and ISO 1609) allows components from DN 63 to DN 630 to be connected in any position regardless of the bolt hole arrangement on any fixed flanges. It consists of two clamp flange compnents (1), a centering ring (2) with an outer ring enclosing the O-ring gasket, and several clamps (3) which the connection is assembled and tightened with.

Since the centering ring can be firmly inserted into the centering groove of the flange, even horizontal connections are quickly and easily fitted
