121-0003 - Miller Smith Silverline 2-Stage Regulator 0-60 PSI CGA 326

Rugged Reliability for Maintenance and Fabrication Shops

Equip your facility with the Miller Smith 121-00-03 Silverline Series Regulator, a heavy-duty solution designed to withstand the rigors of daily industrial use. Whether you are running pneumatic tools, purging systems with nitrogen, or managing shield gases in a maintenance shop, this general-purpose regulator delivers the durability and consistency you need. With a maximum inlet pressure rating of 3500 PSI and a working range of 0-60 PSI, it is versatile enough to handle a wide variety of non-corrosive gas applications.

Set It and Forget It

Efficiency in the shop means spending less time adjusting equipment and more time getting the job done. The two-stage architecture of the 121-00-03 is a game-changer for long-duration tasks. In standard single-stage regulators, you often have to constantly tweak the pressure knob as your gas tank empties to prevent pressure spikes. This Silverline regulator eliminates that hassle by automatically compensating for dropping cylinder pressure, maintaining your set output exactly where you need it from a full tank down to the last few PSI.

Industrial-Grade Construction

Miller Smith understands that shop tools take a beating. That’s why this regulator is machined from solid brass bar stock rather than forged or die-cast materials, offering superior structural integrity. The plated finish on the body and bonnet adds an extra layer of defense against scratches and corrosion. The large 2-1/2 inch gauges are designed for high visibility, allowing technicians to check tank levels and line pressure at a glance, even from a distance.

Safety and Versatility

Safety is built-in with a preset relief valve that vents to the atmosphere, ensuring the regulator never exceeds safe operating limits. While it comes with a CGA 326 fitting, it is compatible with a range of inert gases including Air, Nitrogen, and Argon, making it a flexible asset for your tool crib. The filtered seat design also means less downtime for repairs, as it blocks contaminants that typically cause regulator failure. Backed by the Miller True Blue Warranty, this is an investment in quality that pays for itself in reliability.
