Airgas Model C645D Stainless Steel High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Threaded SeatThis series of two stage, high purity 316 stainless steel regulators is designed for non corrosive analytical and process applications requiring precise, stable delivery pressure control. The two stage design yields a delivery pressure change of less than 0. 04 100 psi inlet change. Convoluted 316 stainless steel diaphragms provide excellent regulating characteristics and corrosion resistance, and the threaded seat design allows for internal vacuum

The optional bonnet vent adapter enables venting hazardous gases in the event of diaphragm failure

This series of high-purity

Direct cylinder connection is only permissible when using liquefied compressed gases with vapor pressures below 250 psig such as 1

This design is specifically made for processes using analyzers and mixes gases with low levels of the gas components

SAE J845 Class I

Heavy duty vinyl material

They are available with 973 pin-indexed yoke connection for use with E medical cylinders

and certain chemicals
