Reliance RWC Red 2116 Rubber Seat Pressure Relief Expansion Cartridge 3 Bar ZRC214043

The CONCOA 332 Series is a five-port, stainless steel, dual-stage cylinder regulator designed for primary pressure control of high-purity inert gases (up to grade 5.5), including mildly reactive gases—but not toxic or highly corrosive gases. Its two-stage design minimizes pressure fluctuations from cylinder depletion, providing stable delivery pressure for critical applications. Factory-configurable options make it ideal for university labs, research facilities, and pharmaceutical manufacturing.
