Most specialty gases are compressed in the cylinder with really high pressure and we cannot use these high - pressure gas directly, so we need to use Gas Pressure Regulator to reduce the gas pressure. Gas Pressure Regulator can help us to reduce the pressure within the cylinders to a low level so we can use the gases safely. We supply various Gas Regulator for the different function, most regulator we supply have two gauge display the cylinder pressure and working pressure. Please look at the product description for different Gas pressure Regulator.
