Miller Smith 320 Series High Purity Two-Stage Stainless Steel Regulator, CGA 350, 0-25 PSI

Reliable Performance in Harsh Environments

When working with specialty gases, reliability and safety are non-negotiable. The Miller Smith 320 Series Stainless Steel Regulator delivers professional-grade performance for welders and industrial technicians handling hydrogen, methane, or other gases requiring a CGA 350 connection. Built to last, this regulator features a robust 316 stainless steel construction that stands up to corrosive environments that would destroy standard brass regulators. Whether you are managing process gases in a refinery or setting up a high-precision lab station, this tool provides the durability you need.

The two-stage design of the 320 Series is a game-changer for long-duration tasks. Standard single-stage regulators allow the outlet pressure to creep up as the tank pressure drops, requiring constant attention and adjustment. This two-stage model automatically compensates for tank pressure decay, delivering a rock-steady 0-25 PSI flow from the moment you open the valve until the tank is empty. This consistency allows you to focus on your work rather than monitoring your gauges. The large, 2-1/2 inch gauges are easy to read at a glance, providing clear indication of both tank and delivery pressure.

Safety is built into every aspect of this regulator. It features a captured vent port system, which is an essential feature when working with flammable or toxic gases. This allows you to connect a vent line to the regulator bonnet, ensuring that if a leak were ever to occur, the gas is safely diverted away from the workspace. The regulator also includes a 316 stainless steel filtered seat to catch particulates, protecting the internal components and extending the service life of the equipment. With a max inlet rating of 3500 PSI, this regulator is ready for high-pressure cylinders and demanding industrial applications.
