Airgas Model N245A540 Brass High Purity Two Stage Pressure Regulator With 1/4" FNPT Connection And Non-Lubricated Check Valve Low Pressure these regulators are equipped withThis series of two stage, high purity regulators is designed for non corrosive analytical and process applications requiring precise, stable, delivery pressure control. The two stage design yields a delivery pressure of less than 0. 02 100 psi inlet change. These regulators come with a CGA nipple that has a special high purity, non lubricated check valve incorporated into nose and prevents air and contaminants from entering the gas stream during
