221-2006 - Miller Smith 221-20-06 Silverline High Purity 2-Stage Regulator CGA 350

Rugged Reliability for Specialty Gas Control

The Miller Smith 221-20-06 Silverline Regulator brings industrial-grade durability to high-precision gas control. While designed for analytical applications, its robust construction makes it a favorite among professionals who require dependable performance in demanding environments. Built from rugged brass bar stock and finished with a protective plating, this regulator resists corrosion and withstands the wear and tear of daily use. It is specifically configured with a CGA 350 connection, standard for hydrogen and fuel gas mixtures, and delivers a precise pressure range of 0-50 PSIG.

Consistent Delivery Pressure

For welders and fabricators utilizing specialized setups that require stable low-pressure delivery, the two-stage design of the 221-20-06 is a game-changer. Single-stage regulators often suffer from "decay," where the outlet pressure rises as the cylinder pressure falls. This two-stage model eliminates that issue, providing a flat, consistent delivery pressure from a full cylinder down to the last few pounds. This feature is particularly beneficial for long-duration TIG purging or specialized chamber welding where pressure fluctuations can compromise the weld atmosphere.

User-Friendly Design

Miller Smith has prioritized usability with large, 2-1/2 inch single-scale gauges that are easy to read at a glance, even from a distance. The gauges are plated to match the body, providing superior protection against external damage. The outlet is equipped with a 1/4" MNPT needle valve, allowing for fine-tuning of flow rates directly at the regulator, which simplifies setup and reduces the need for additional downstream valves. The stainless steel diaphragm not only ensures accuracy but also provides a longer fatigue life compared to elastomeric diaphragms.

Miller True Blue Warranty

Invest in confidence with Miller's reputation for quality. The Silverline series represents the intersection of laboratory precision and industrial toughness. Whether you are setting up a laser resonator, a specialized test bench, or a high-tech welding station, the 221-20-06 delivers the performance you need. The integrated safety relief valve and vacuum-compatible design add layers of safety and versatility, ensuring this regulator is ready for whatever the job demands.
