Gas Regulator for Hydrogen and Methane
This Miller-Smith Equipment regulator controls gas flow from cylinders containing hydrogen or methane. It is built for general-purpose welding and cutting tasks where those fuel gases are used. The single-stage design delivers a steady outlet pressure up to 100 psi. It suits technicians who need reliable pressure control for specific gas types.
Brass Body with CGA-350 Inlet and Left-Hand Outlet
The brass body and neoprene diaphragm resist wear from industrial gases. A CGA-350 inlet connects directly to compatible hydrogen or methane cylinders. The 9/16 in. -18 LH B outlet fits standard left-hand torch fittings. A 2.0 in. body diameter and 2 in. gauges allow clear reading of supply pressure up to 4,000 psi and delivery pressure.
Filtered Seat and UL Listing for Clean Operation
The Sure Seat filtered seat helps prevent contamination from entering the regulator mechanism. A bright nickel-plated bonnet adds corrosion resistance to the adjusting assembly. UL listing confirms the unit meets recognised safety standards for gas regulation. These features reduce maintenance downtime and support consistent gas delivery.
