121-2009 - Miller Smith Silverline 2-Stage Inert Gas Regulator 0-60 PSI CGA 580

Rugged Reliability for Maintenance and Fabrication

The Miller Smith 121-20-09 Silverline Series Regulator is a workhorse designed for general plant maintenance, fabrication shops, and industrial applications requiring dependable inert gas control. Built to withstand the rigors of daily shop use, this regulator features a solid brass bar stock body that is plated for superior protection against corrosion and wear. Its two-stage design is a significant advantage for welders and fabricators who need consistent performance; it automatically compensates for the drop in cylinder pressure as the tank empties, eliminating the need for frequent manual adjustments and ensuring a steady flow for shielding or purging applications.

With a maximum inlet pressure rating of 3500 PSIG and a delivery range of 0-60 PSIG, this regulator is versatile enough to handle high-pressure cylinders and deliver precise low-pressure output. The unit comes equipped with a CGA 580 inlet connection, making it compatible with standard Argon, Nitrogen, and Helium cylinders. The outlet features a chrome-plated needle valve with 1/4" MNPT threading, providing operators with the ability to shut off or throttle flow directly at the regulator. This is particularly useful in maintenance shops where equipment setups may vary frequently.

Miller Smith's attention to detail is evident in the Sure-Seat technology, which protects the internal components from contaminants that often cause regulator failure. The filtered seat design ensures that the regulator maintains a tight seal and accurate pressure control over a long service life. Additionally, the body is tapped for rear panel mounting, offering flexibility for installation in custom gas manifolds or test benches. Backed by the quality assurance of the Miller brand, the 121-20-09 Silverline regulator is an investment in efficiency and safety for any professional industrial environment.
