Reliable Control for Inert Gases

When you need a dependable regulator for your shop's nitrogen purge, argon supply, or general air lines, the Miller Smith 113-40-09 Silverline Series is a top-tier choice. Built by one of the most trusted names in the industry, this single-stage regulator is designed to handle the daily grind of welding and fabrication environments. It connects easily to standard inert gas cylinders with a CGA 580 fitting and delivers a steady pressure output up to 250 PSI.

Built Tough for the Shop
Cheap regulators often fail because of weak internal components or flimsy bodies. The Silverline 113-40-09 features a solid brass bar stock body that can take a beating. Miller has also plated the exterior components—including the bonnet and gauges—to resist rust and corrosion, keeping your equipment looking and working like new for longer. The large 2-1/2 inch gauges are easy to read even from a distance, so you always know your tank levels and line pressure.

Clean and Consistent Flow
Contaminants in your gas line can ruin welds and damage equipment. This regulator features a filtered seat that traps debris before it causes problems, ensuring the gas downstream remains pure. The large internal diaphragm provides smooth pressure adjustment, giving you the control you need without constant fluctuation. Whether you are pressure testing a system with nitrogen or running shielding gas for a large project, this regulator delivers the performance you expect from Miller Smith.
