Flame Tech HPPR-IN-700-580 High Pressure Piston Regulator is an excellent welding gas regulator for inert gases including nitrogen gas and argon gas. With 2 inches gauge diameter, the regulator comes with a forged brass body and bonnet for optimum strength. The argon and nitrogen regulator can take a maximum of 0-3000 PSI inlet pressure while the piston design helps in precisely stabilizing the control. There is an easy-to-read dual-scale gauge with a hardy acrylic screw-on lens on our welding unit. The scale measures 2-½” gauges and helps the user get the perfect and clear reading every time. To efficiently refine impurities from the gas, our 3.8 lbs Piston Regulator with a 1/4 inch hose has an advanced sintered metal inlet filter. The easy-to-maintain argon gas and nitrogen gas regulator does not have any soldered joints. Flame Tech HPPR-IN-700-580 High Pressure Piston Regulator for inert gases is an ideal solution for environmental conditions with intense delivery pressure. The welding gas regulator can easily bear up to PSI 50-700 delivery pressure. The CGA connection is 580.
