Miller Smith 620 Series High Purity CO2 Regulator, 2-Stage, 0-250 PSI

Unmatched Stability for Industrial Fabrication

For welders and fabricators who require absolute consistency in their gas delivery, the Miller Smith 623-20-02-00-00 Silverline Regulator stands out as a premium choice. While often used in laboratory settings, its robust construction and two-stage performance make it an excellent upgrade for high-end industrial applications using Carbon Dioxide. The primary advantage of this two-stage system is its ability to maintain a constant delivery pressure throughout the entire life of the cylinder. You can set your pressure to the desired level—anywhere from 0 to 250 PSI—and trust that it will not creep or drop as your tank runs low, eliminating the need for constant readjustment.

Durability is key in any shop environment, and the Miller Smith 620 Series delivers with a heavy-duty nickel-plated brass body. This plating not only looks good but provides an extra layer of corrosion resistance against shop fumes and humidity. The regulator features large, easy-to-read 2-1/2 inch single scale gauges, allowing operators to monitor cylinder and delivery pressure at a glance. The included filtered seat adds another layer of reliability, trapping microscopic particles that could otherwise damage the seat and cause creeping or leaks.

This model comes equipped with a CGA 320 connection for CO2 cylinders and features a 1/4" Male NPT outlet with a chrome needle valve, giving you fine-tuned control over your flow rate immediately. Whether you are setting up a custom TIG welding station, a laser cutting assist gas supply, or a specialized purging rig, the reliability of the stainless steel diaphragm and the precision of the two-stage mechanism ensure that your gas equipment is the strongest link in your production chain.
