Airgas Model C445B320 Supelcoat™ Coated Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless SeatThis series of 316 stainless steel two stage high purity regulators is designed for non corrosive analytical, mildly corrosive and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 01 100 psi inlet change. Convoluted Hastelloy C 22 diaphragms provide excellent regulating characteristics and allow for internal vacuum purging. The metal to metal diaphragm seal
