121-0002 - Miller Smith Silverline 2-Stage CO2 Regulator 0-60 PSI CGA 320

Reliable CO2 Control for Your Shop

When consistency counts, the Miller Smith Silverline Series 121-00-02 Two-Stage Regulator delivers. Designed for welders, fabricators, and lab technicians who rely on Carbon Dioxide (CO2), this regulator takes the guesswork out of gas management. Unlike single-stage regulators that can allow outlet pressure to creep up as your tank gets low, this two-stage workhorse maintains a rock-steady flow from the moment you crack the valve until the cylinder is empty. This means you spend less time adjusting knobs and more time focused on your work.

Durability is built into every inch of this tool. The body is machined from solid brass bar stock and plated for a clean, professional finish that resists shop grime and corrosion. Inside, Miller Smith's legendary Sure-Seat technology works as a first line of defense, filtering out microscopic debris that often destroys lesser regulators. This added protection ensures your investment lasts longer and performs better, even in dusty shop environments.

Reading your pressures is effortless thanks to the oversized 2-1/2 inch gauges, which are easy to see even from a distance. With a delivery range of 0-60 PSI, this regulator provides the fine-tuned control needed for shielding gas applications, beverage systems, or general maintenance tasks. Whether you are outfitting a new station or upgrading old equipment, the Silverline 120 Series offers the professional-grade reliability that has made Miller Smith a trusted name in the industry.
