120-8400 - Miller Smith Silverline 120 Series Two-Stage Inert Gas Regulator, 0-30 PSI

Precision Control for Professional Gas Management

When your work demands absolute consistency, the Miller Smith 120-84-00 Silverline Series Two-Stage Regulator delivers the performance you need. Designed for professionals in laboratories, maintenance shops, and general fabrication facilities, this regulator takes the guesswork out of gas pressure control. Unlike standard single-stage regulators that can allow delivery pressure to fluctuate as your gas cylinder empties, this two-stage powerhouse maintains a steady, constant flow from the moment you open the valve until the tank is nearly empty. This feature is essential for precision applications where even a small variance in pressure could compromise the quality of your work or experiment.

Built to Last
Durability is at the core of the Silverline Series. The 120-84-00 is constructed from solid brass bar stock and finished with high-quality plating on the body, bonnet, and gauges. This rugged design ensures the regulator can withstand the daily wear and tear of industrial environments while resisting corrosion. The large, easy-to-read 2-1/2 inch gauges allow you to check your settings quickly and accurately, reducing setup time and minimizing errors.

Advanced Protection and Versatility
Miller Smith has integrated their advanced Sure-Seat technology into this model, which filters the gas stream to protect the internal seat from debris. This not only ensures the purity of your gas—critical for sensitive inert gas applications like Argon or Nitrogen purging—but also extends the lifespan of the regulator itself. Whether you are setting up a custom panel mount system using the 1/4" FNPT inlet or simply need a reliable benchtop regulator, the 120-84-00 offers the flexibility and reliability that serious welders and technicians trust. It is the ideal choice for managing Air, Nitrogen, CO2, and Argon with confidence.
