Specifications:The body of the pressure reducer adopts scientific industrial design, which has good pressure resistance and air leakage.The glass dial is clearly visible, and is covered with a nonslip and shockproof plastic protective cover, which is shockproof and durable.Comes with a safety protection valve, when the output pressure is stronger than 1.3 times the rated pressure, the pressure reducing valve will automatically open the valve to vent and reduce pressure.Pressure reducer interface adopts a highdensity molecular brass filter, which can effectively prevent the impurities in the gas cylinder from entering the meter with the gas, ensuring the normal operation of the meter and improving the service life.
