OVERVIEW

Reliable Two-Stage Performance for the Shop

When your work requires a steady flame or consistent flow, you can't afford a regulator that fluctuates. The Miller Smith 120-40-06 is a workhorse two-stage regulator designed to give you "set it and forget it" performance. By stepping down the pressure in two stages, it eliminates the "end-of-tank dump" or pressure rise common with single-stage regulators. This means you don't have to constantly adjust your settings as your gas cylinder gets low, saving you time and frustration.

Built tough for the shop environment, this regulator features a solid brass body that can take a beating. The CGA 350 connection makes it the right tool for Hydrogen and Methane applications. Whether you are running a specialized heating torch, a laboratory setup, or a maintenance rig, the 0-30 PSIG delivery range gives you fine-tuned control for low-pressure requirements. The large 2-1/2 inch gauges are clear and easy to read, even from a distance, so you always know where your levels stand.

Miller Smith's Silverline Series is known for longevity. The filtered seat design keeps dirt and debris out of the critical sealing areas, which is the number one cause of regulator failure. This added protection means fewer repairs and a longer life for your equipment. If you are working with fuel gases like Hydrogen or Methane and need a regulator that prioritizes safety, consistency, and durability, the 120-40-06 is the professional's choice.

FAQ

A single-stage regulator reduces cylinder pressure to delivery pressure in one step, which can cause delivery pressure to rise as the cylinder empties. A two-stage regulator reduces pressure in two steps, providing a constant delivery pressure regardless of the cylinder's remaining volume.

The CGA 350 fitting is the standard connection for Hydrogen, Methane, Natural Gas, and Carbon Monoxide. It is not compatible with Inert gases like Argon or Helium.

No. This regulator comes with a CGA 350 connection. Argon cylinders use CGA 580, and CO2 cylinders use CGA 320. You must use a regulator with the correct CGA fitting for your specific gas cylinder.

The Miller Smith 120-40-06 is rated for a maximum inlet pressure of 3500 PSIG.

This regulator allows for adjustment of delivery pressure between 0 and 30 PSIG.

Yes, it is covered by the Miller True Blue Warranty, typically offering 3 years on regulators (check specific warranty documentation for details).

No. This is a brass regulator intended for non-corrosive gases. Corrosive applications typically require stainless steel or monel construction.
