Airgas Model C445A660 Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat Single Stage while the encapsulated filters assembly

while the encapsulated filters assembly protect the valve seats and extends operating service life

This minimizes cleanup time in vacuum purging and yields lower residual contaminant levels

CR-80 Repel is made of the patented CarbonX blend of high-performance fibers and a proprietary compound that enables the fabric to remarkably shed molten metal

extending regulator service life while also reducing velocity of gas when opening high-pressure cylinder valves

Airgas Model C445A660 Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threadless Seat Single Stage while the encapsulated filters assemblyThis series of 316 stainless steel two stage high purity regulators is designed for non corrosive analytical, mildly corrossive 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
