CONCOA 425 Series Regulator

The FSSUMSU Sealed Unit Rupture Discs feature a convenient threaded connector and comprise two parts that house a calibrated rupture disc. This rupture disc is meticulously inserted into a threaded and sealed container, making it easy to mount small discs within plants. Designed for reliability, these units simplify handling, eliminating the need for specialised personnel. FSSUMSU sealed units are adept at managing both gases and liquids, even in cyclical and pulsating conditions. They respond to over-pressure in mere milliseconds, offering essential protection for plants, plant equipment, and containers.
