123-0005 - Miller Smith Silverline 2-Stage Air Regulator CGA 346 250 PSI

Rugged Reliability for the Shop Floor

When you are running pneumatic tools or managing air supply in a busy fabrication shop, you need equipment that you can set and forget. The Miller Smith 123-00-05 Silverline Two-Stage Regulator delivers exactly that. As a two-stage regulator, it performs the work of two regulators in one body: the first stage reduces the high pressure from the tank to an intermediate level, and the second stage delivers the precise pressure you set to your tools. This means that even as your air tank drains from 3000 PSI down to 500 PSI, your tool pressure stays rock solid. You won't have to stop working to tweak the knob, saving you time and frustration.

Durability is a key factor in any welding or maintenance shop environment, and the Miller Smith 123-00-05 is built like a tank. The body isn't made from cheap die-cast metal; it is machined from solid brass bar stock, providing exceptional strength and resistance to cross-threading or impact damage. The entire unit, including the bonnet and gauges, is plated to shrug off grime, sparks, and corrosion. The 2-1/2 inch gauges are large and easy to read at a glance, featuring high-contrast scales that let you monitor your tank level and delivery pressure from a distance. This ensures you are never caught off guard by an empty cylinder in the middle of a job.

Safety and longevity are also built-in. The regulator features a filtered seat that stops dirt and metal shavings from the cylinder valve from entering the regulator mechanism. This "Sure-Seat" protection prevents leaks and extends the life of the regulator significantly. The 123-00-05 is designed for Industrial Air cylinders with a CGA 346 fitting and can deliver up to 250 PSI, making it powerful enough for heavy-duty pneumatic equipment, pressure testing rigs, and general shop air distribution. Backed by the reputation of Miller Electric, this regulator is a solid investment for any shop looking to upgrade their gas control equipment to professional standards.
