OVERVIEW

Heavy-Duty Two-Stage Regulation for the Shop

Upgrade your gas control setup with the Miller Smith 122-00-09 Silverline Series Regulator, a premium solution for handling inert gases in welding, automotive, and industrial shops. When consistency matters, a two-stage regulator is the superior choice. This unit is designed to take the fluctuation out of your gas supply, delivering a constant 0-100 PSIG output regardless of how much gas is left in your tank. It is the ideal "set it and forget it" tool for busy professionals.

Built for Performance

The 122-00-09 is equipped with a CGA 580 connection, compatible with standard Argon, Nitrogen, and Helium cylinders. With a maximum inlet pressure rating of 3500 PSIG, it is ready to handle modern high-pressure cylinders without breaking a sweat. The outlet is a 1/4" FNPT connection, offering versatility to attach various hose barbs, adapters, or hard-piping setups depending on your specific shop requirements.

Why Choose the Silverline Series?

Smith Equipment (now Miller) has long been the gold standard for gas equipment, and the Silverline Series continues that legacy. The regulator features Sure-Seat technology, which protects the seat from debris and wear, ensuring that your regulator doesn't develop creep or leaks over time. The rugged brass bar stock body is far tougher than the lightweight alloy regulators found elsewhere, capable of withstanding the accidental bumps and knocks of daily shop life.

Key Benefits for Welders and Fabricators:

  • Stable Flow: Perfect for TIG purging applications where pressure spikes could blow out a purge dam or waste expensive gas.
  • Safety First: Includes a preset safety relief valve to vent excess pressure to the atmosphere, adding a layer of safety for non-hazardous gas applications.
  • Easy Monitoring: The oversized 2-1/2 inch gauges are easy to read from a distance, so you always know your status.

Invest in the Miller Smith 122-00-09 for a regulator that works as hard as you do, backed by the quality assurance of the Miller True Blue warranty.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure even as the cylinder empties. A single-stage regulator's delivery pressure may fluctuate (rise) as the tank pressure drops.

This regulator comes with a CGA 580 inlet, making it compatible with inert gases such as Argon, Nitrogen, and Helium. It is not for use with Oxygen or Flammable gases.

The regulator features a 1/4" FNPT (Female National Pipe Thread) outlet connection, allowing for the attachment of various fittings or hose barbs.

While the regulator internals are compatible with CO2, the CGA 580 connection is not. CO2 cylinders typically use CGA 320. You would need a different regulator or an approved adapter, though using the correct CGA fitting is always recommended.

The Miller Smith 122-00-09 is rated for a maximum inlet pressure of 3500 PSIG.

Yes, as a Miller Smith product, it is covered by the Miller True Blue Warranty. Please check the specific warranty documentation for duration and terms.

No, this is a general-purpose brass regulator intended for inert and non-corrosive gases only. Corrosive gases require stainless steel or Monel regulators.

This specific model (122-00-09) has a delivery pressure range of 0-100 PSIG.
