121-0006 - Miller Smith Silverline 120 Series Two-Stage Regulator CGA 350

Reliable Precision with the Miller Smith Silverline Series

For welders, fabricators, and lab technicians who demand consistency, the Miller Smith 121-00-06 Silverline General Purpose Two Stage Regulator delivers unwavering performance. When you are working on critical projects, the last thing you need is your gas pressure drifting as your tank gets low. That is where the two-stage design of this regulator shines. Unlike single-stage models that require frequent adjustment as the cylinder pressure drops, this Silverline regulator compensates automatically, providing a steady, reliable flow of gas from the moment you crack the valve until the tank is empty. It is the ideal choice for general plant maintenance, shops, and laboratories where constant delivery pressure is non-negotiable.

Built to withstand the rigors of daily industrial use, the 121-00-06 features a heavy-duty brass bar stock body that is far more durable than cast alternatives. The entire unit—including the body, bonnet, and gauges—is plated to resist corrosion and keep your equipment looking and functioning like new for years. The large 2-1/2 inch gauges are designed for clarity, making it easy to check your settings from a distance. Inside, Miller's Sure-Seat technology works to filter out debris that often causes regulators to fail prematurely, ensuring that your investment lasts longer and performs better.

This specific model comes equipped with a CGA 350 connection and is calibrated for a delivery range of 0-60 PSIG, making it versatile for a variety of inert gas applications including Nitrogen, Argon, CO2, and Air. Whether you are purging lines, running pneumatic tools, or managing shield gas for specialized welding setups, this regulator offers the control you need. Backed by the Miller True Blue Warranty, you can trust in the quality and support that comes with the Miller name. Upgrade your gas management system with a regulator that combines laboratory precision with industrial toughness.
