ISO Flanges & Fittings

ISO-K flanges
ISO-K flanges are joined around the periphery with Double Claw Clamps. Instead of Double Claw Clamps we also offer rotatable bolt ring and retainer ring. This fixturing adapts a ISO-K flange into a rotatable ISO-F flange. Single claw clamps are used to join a ISO-K flange to a tapped nonrotatable flange from a pump or gate valve.

ISO-F flanges
ISO-F flanges are non-rotatable ISO flanges which are assembled with bolts. They do not allow rotation of bolt holes on mating flanges to align components.

ISO dimensions
ISO Flanges are available in bore sizes ranging from 63mm to 630mm.
