121-8203 - Miller Smith Silverline 2-Stage Regulator CGA 326 0-60 PSI

Reliable Gas Control with Miller Smith Silverline

For welders, fabricators, and maintenance professionals who demand consistency in their gas delivery systems, the Miller Smith 121-82-03 Silverline Series regulator is a top-tier choice. When you are working on critical projects, the last thing you want to worry about is your gas pressure fluctuating as your tank runs low. This two-stage regulator solves that problem completely. Unlike single-stage regulators that require frequent adjustment as the cylinder empties, the 121-82-03 maintains a steady 0-60 PSIG delivery pressure from the moment you crack the valve until the tank is empty. This "set it and forget it" reliability allows you to focus entirely on your work.

Built for the Shop Environment

Industrial environments can be tough on equipment, but the Silverline series is built to withstand the abuse. The regulator features a solid brass body that is machined from bar stock—not a cheap casting—ensuring structural integrity. To keep it looking professional and protected from shop grime and corrosion, the entire body, bonnet, and gauge housing are nickel-plated. This not only adds a layer of durability but also makes the unit easy to wipe down and keep clean. The large 2-1/2 inch gauges are easy to read from a distance, so you can check your tank levels and line pressure with a quick glance across the shop.

Precision and Safety Features

Safety and precision go hand in hand with Miller Smith products. This regulator includes a Sure-Seat filtered seat technology that prevents debris from entering the high-pressure seat area, a common cause of regulator failure. This means less downtime for repairs and a longer lifespan for your equipment. The large diaphragm allows for smooth pressure adjustments, giving you the exact flow you need for your specific application. Whether you are purging lines with nitrogen, running pneumatic tools, or managing shield gas in a central system, this regulator delivers the performance you expect from the Miller brand.

Application Versatility

This specific model comes with a CGA 326 connection and is rated for a variety of inert gases including Argon, Nitrogen, and CO2. It is an excellent addition to any maintenance cart or laboratory bench where low-pressure delivery (up to 60 PSI) is required. The rear-panel mounting capability also makes it a versatile option for fixed installations or custom gas manifolds. Invest in the Silverline 121-82-03 for a regulator that combines professional-grade durability with laboratory-grade precision.
