Airgas Single Stage Brass 0-100 psi Analytical Cylinder Regulator CGA-590 With Needle Outlet Single Stage The check valve cylinder connectionThis analytical series of high purity brass single stage regulators is recommended for non corrosive analytical and process applications where precise pressure control is not required. The check valve cylinder connection prevents air and contaminants from entering the gas stream during cylinder change out. This creates consistencies in processes and extends column life in GC applications. Machined from brass bar stock, this regulator body has minimal
