Miller Smith Silverline 220 Series High Purity Two-Stage Regulator CGA 350

Rugged Reliability for Specialty Gases

When your operation requires the handling of specialty gases like Hydrogen or Methane mixtures, the Miller Smith 222-42-06 Silverline Regulator delivers the reliability and safety you need. While often found in laboratory settings, the robust construction of this regulator makes it equally suitable for industrial applications requiring high-purity gas delivery. The regulator features a rugged brass bar stock construction that is fully chrome-plated—including the body, bonnet, and gauge cases. This plating not only looks professional but provides a hard-wearing shield against corrosion and wear, ensuring the tool withstands the rigors of daily use.

The 222-42-06 is a two-stage regulator, a configuration preferred for its ability to maintain a steady outlet pressure as the supply cylinder empties. This means you won't have to constantly adjust the regulator as you work through a tank, saving time and ensuring process consistency. It is rated for a maximum inlet pressure of 3500 PSIG and provides a delivery pressure range of 0-100 PSIG, adjustable via a precise control knob. The inclusion of a stainless steel diaphragm ensures precise pressure control and eliminates the risk of rubber or neoprene contamination in the gas line.

Equipped with a CGA 350 inlet connection, this unit is specifically designed for use with flammable gases such as Hydrogen and Methane. It comes standard with a 1/8-inch tube stainless steel needle valve on the outlet, offering fine flow control right out of the box. The large 2-1/2 inch gauges provide clear visibility of your pressure settings. Additionally, the automatic reseating safety relief valve offers peace of mind by protecting the regulator internals and downstream equipment. Whether for calibration stations, laser mixes, or specialized welding atmospheres, the Miller Smith 222-42-06 combines heavy-duty build quality with analytical precision.
