Collection: ISO HV Flanges

ISO-K and ISO-F are two common high-vacuum flange types, differing primarily in their fixing methods. ISO-K utilizes a snap-on fixing system, with flange claws and a sealing ring creating a seal. ISO-F utilizes bolted fixing, tightly connecting the flange to the retaining ring, sealing ring, and other components. 

Both types can achieve a from atmosphere to ~10-8 torr or mbar., making them suitable for high-vacuum systems. Most models operate stably in environments ranging from 0°C to 180°C.
