Miller Smith Silverline 620 Series Two-Stage CO2 Regulator, 0-100 PSI Delivery

Reliable CO2 Delivery for Demanding Setups

When your welding or industrial process relies on consistent gas flow, the Miller Smith 622-00-02-00-00 Silverline Regulator delivers performance you can trust. While standard regulators might fluctuate as your tank pressure drops, this premium two-stage regulator keeps your delivery pressure locked in at your set point—up to 100 PSI—until the cylinder is practically empty. This means less time adjusting knobs and more time focusing on your work. The CGA 320 connection is designed specifically for Carbon Dioxide cylinders, making it a perfect upgrade for high-end MIG welding stations, beverage systems, or specialized industrial applications requiring pure CO2.

Durability is built into every inch of the Silverline series. The body is crafted from solid brass bar stock and finished with nickel plating, giving it superior resistance to wear and corrosion compared to standard forged bodies. Inside, a stainless steel diaphragm replaces the common rubber components found in cheaper regulators. This not only extends the service life of the unit but also ensures that the regulator performs consistently in varying temperatures and conditions. The metal-to-metal seals ensure a leak-tight fit that holds up to the rigors of daily shop use.

Miller Smith has equipped this model with features that make operation safe and straightforward. The large 2-1/2 inch gauge is easy to read at a glance, allowing you to monitor delivery pressure accurately. The regulator also includes a filtered seat that traps microscopic debris from the tank before it can damage the internal valve mechanism, preventing creeping pressure and costly failures. Whether you are setting up a precision fabrication station or a laboratory-grade gas delivery system, the Miller Smith 622-00-02-00-00 offers the reliability and 'True Blue' quality that industry professionals expect.
