120-8406 - Miller Smith Silverline 2-Stage Hydrogen/Methane Regulator 15 PSI

Reliable Performance for the Shop and Field

When consistency is key, the Miller Smith 120-84-06 Silverline Series Two Stage Regulator delivers. Designed for professionals who demand equipment that works as hard as they do, this regulator takes the guesswork out of gas control. The two-stage mechanism is the heart of this unit; it automatically compensates for the drop in cylinder pressure as you work, meaning you won't have to constantly walk back to the tank to adjust your settings. You set it once, and it holds that pressure until the tank is empty.

Durability is built into every component. The regulator starts with a solid brass bar stock body, which is then nickel-plated. This plating doesn't just look professional—it adds a layer of armor against the bumps, scrapes, and corrosive elements found in busy workshops and industrial sites. The gauges are large (2-1/2 inches) and easy to read from a distance, so you can check your status at a glance. The 15 PSI delivery range gives you fine control for low-pressure applications, ensuring you don't over-pressurize sensitive downstream components.

Important Compatibility Note: This regulator comes with a CGA 350 fitting. This connection is standard for Hydrogen, Methane, and Natural Gas cylinders. It features a Left-Hand thread on the outlet (9/16-18 LH) to prevent accidental connection to incompatible lines, keeping your operation safe. The filtered seat design adds another layer of reliability, protecting the internal components from dirt and scale that might be inside older cylinders.

Backed by the Miller True Blue Warranty, the 120-84-06 is a solid investment for any operation using CGA 350 gases. It combines the heavy-duty construction of an industrial tool with the precision of a laboratory instrument, making it a versatile choice for general plant maintenance, specialized welding applications, or fabrication shops requiring precise fuel gas control.
