ISO-MF Vacuum Flange Components

ISO large flange vacuum fittings and components are commonly referred to as ISO-MF (multi-fastener flange), ISO-LF (large flange), ISO-K, ISO-BF (bolted flange) ISO Universal, or as plain "ISO" flanges. Our Series 76 ISO vacuum components are a quick operating modular system for vacuum construction with flanging ranging from 2.5 to 24 inches (NW63 to NW630). The seal is on a symmetrical centering ring that interfaces with two identical flanges allowing rotation. In addition, ISO vacuum flanges are more compact than ASA flanges, which were designed for pressure and are unnecessarily massive for vacuum use. Since these flanges are an ISO standard, they can be used with components from other manufacturers.
