Specially designed for acetylene service, these unique, single-stage regulators are engineered to provide precision performance. The regulators feature a 10-micron, sintered stainless steel filter and a PTFE-lined, nylon-reinforced neoprene diaphragm. Because delivery pressure of acetylene should not exceed 15 psig, these regulators are equipped with a special pressure gauge that features a red warning to indicate unsafe delivery pressure. They are also equipped with a reverse-flow check valve to prevent backflow of gas into the regulator on the outlet.
