120-4109 - Miller Smith Silverline 2-Stage Inert Gas Regulator 0-15 PSI CGA 580 with Needle Valve

Reliable Gas Regulation for the Shop Floor

When your work demands consistency, the Miller Smith 120-41-09 Silverline Series Regulator delivers. Built for pros who need steady gas flow without the hassle of constant readjustment, this two-stage regulator is a workhorse for inert gas applications. Whether you are running Nitrogen for purging, Argon for shielding, or general shop air, this unit ensures that your output pressure stays locked in at your set point, even as your tank pressure drops. With a delivery range of 0-15 PSIG, it is perfectly suited for low-pressure applications where accuracy counts.

Built Tough for Industrial Use

Shop environments can be tough on equipment, but the Silverline 120 Series is designed to take it. The body is machined from solid brass bar stock—not forged—giving it exceptional structural integrity. To top it off, the body, bonnet, and gauges are chrome-plated, offering a layer of armor against corrosion, scratches, and grime. This isn't just a delicate lab instrument; it's a rugged tool ready for the maintenance shop, fabrication floor, or general plant use.

Set It and Forget It

The primary advantage of this two-stage regulator is stability. In a single-stage regulator, as your cylinder empties, the outlet pressure can creep up, forcing you to stop and tweak the knob. The 120-41-09 eliminates this drift. By stepping down the pressure twice, it provides a smooth, unwavering flow from a full cylinder down to the last few pounds. This means less downtime adjusting settings and more time focused on the job at hand.

Precision and Ease of Use

Reading your pressures shouldn't be a guessing game. This model features large 2-1/2 inch gauges that are clear and easy to read, even from a distance. The included 1/8 inch brass needle valve on the outlet gives you fine-tuned control right at the source, perfect for dialing in exact flow rates for sensitive equipment. With Miller's Sure-Seat filtered seat technology, you also get the peace of mind that internal components are protected from contaminants, ensuring a long, trouble-free service life.
