220-4109 - Miller Smith Silverline 220 Series High Purity Two-Stage Regulator, CGA 580, 0-15 PSIG

Reliable Precision for Specialty Gases

When your work demands more than just a standard industrial regulator, the Miller Smith 220-41-09 Silverline delivers the high-end performance you need. Built for professionals working with specialty gases, this two-stage regulator takes the guesswork out of pressure control. Whether you are setting up a lab bench, a calibration station, or a specialized welding application requiring ultra-stable shielding gas flow, this unit provides the consistency that standard regulators simply cannot match.

Set It and Forget It

One of the biggest headaches with standard regulators is the "end-of-cylinder" pressure spike. As your tank gets low, outlet pressure can creep up, potentially ruining your process or mixture. The Miller Smith 220 Series solves this with its true two-stage mechanism. It steps the pressure down twice, meaning your delivery pressure stays exactly where you set it—at 15 PSI or lower—regardless of whether your tank has 3000 PSI or 300 PSI left. This stability allows you to focus on your work, not on constantly tweaking your regulator knob.

Built to Last

Don't let the refined "Silverline" look fool you; this regulator is built tough. Constructed from solid brass bar stock and finished with a durable plating, it resists corrosion and wear in tough environments. The stainless steel diaphragm isn't just for purity; it offers superior longevity and sensitivity compared to rubber diaphragms that can dry out or crack over time. The included 1/8" tube brass needle valve gives you fine control over your outlet flow right out of the box.

Key Features for the Pro

• Vacuum Compatible: Can handle system purging without damage.
• Clear Readout: Oversized 2-1/2" gauges make checking your levels easy, even from across the bench.
