Features

ISO Universal Vacuum Flange System

ISO-MF vacuum flange components are a vacuum flanging system for 63 mm to 1000 mm fittings. The dimension criteria are based on requirements established by the International Standards Organization (ISO). There are two flange styles: ISO-MF (multi-fastener flange) and ISO-BF (bolted flange).

There are several advantages in the use of ISO-MF components. The seal is on a symmetrical centering ring that interfaces with two identical flanges allowing for rotation. In addition, ISO-MF flanges are more compact than ASA flanges, which were designed for pressure and are unnecessarily massive for vacuum use.

ISO-MF vacuum flanges and components are made of type 304 stainless steel. Centering ring and seal assemblies are available with an aluminum centering ring and spacer ring, or with a stainless centering ring and an aluminum spacer ring. Rotatable bolt rings and clamps are made of aluminum alloy. Retaining rings are made of steel. Flange seal surfaces are carefully machined and inspected for defects.
