8068435-01-1 shown
Rugged, dual stage cylinder regulator for heavy-duty welding, heating, and cutting applications

The 8400 Series heavy-duty welding, heating, and cutting regulator provides primary pressure control of industrial gas cylinders in applications requiring inlet pressures up to 3000 PSIG (210 BAR) and outlet pressures up to 100 PSIG (7 BAR). Combined with a wide range of delivery pressures and gas compatibility, the CONCOA 8400 Series regulator is perfect for high-precision, high durability welding, heating, and cutting applications.
