OVERVIEW

Stop Adjusting Your Pressure: Upgrade to Two-Stage

Every welder knows the frustration of a single-stage regulator: as your tank gets low, the outlet pressure starts to creep up, forcing you to constantly walk back to the cylinder to adjust the knob. The Miller Smith 123-82-08 Silverline Two-Stage Regulator solves this problem permanently. By stepping down the pressure in two stages, it delivers a rock-steady flow of Oxygen from the moment you crack the valve until the tank is effectively empty. This means consistent flame characteristics for cutting and brazing, or stable pressure for downstream equipment, without the hassle of constant monitoring.

Built for the real world, this regulator isn't just precise; it's tough. The body is machined from solid brass bar stock—no cheap die-cast parts here—and then nickel-plated for extra durability. That shiny finish isn't just for looks; it helps resist corrosion and keeps the regulator looking new even after years of service in a dusty shop. The gauges are large (2-1/2 inches) and easy to read, so you can check your settings from a distance. The 0-250 PSI delivery range gives you plenty of headroom for heavy-duty cutting tips or other shop tools that need higher pressure than a standard 100 PSI regulator can provide.

Safety and longevity are built right in. The Sure-Seat filtered seat technology acts as a first line of defense against dirt and metal shavings that often hide in cylinder valves. By keeping these contaminants away from the critical sealing surfaces, Miller Smith ensures your regulator won't develop dangerous leaks or pressure creep. The outlet is a standard 9/16"-18 Right Hand thread, fitting standard oxygen hoses perfectly. Whether you are running a CNC cutting table, a heavy-duty heating torch, or a custom shop manifold, this regulator provides the reliability and performance professional tradesmen demand.

Key Applications:

  • Heavy-duty oxy-fuel cutting and heating
  • Laboratory gas distribution
  • Pressure testing and purging

FAQ

A two-stage regulator reduces cylinder pressure in two steps, providing a constant delivery pressure regardless of how much gas is left in the cylinder. A single-stage regulator's delivery pressure may fluctuate as the cylinder empties.

This specific model is equipped with a CGA 540 inlet, making it designed for Oxygen service.

The regulator can deliver pressures ranging from 0 to 250 PSI.

No, the CGA 540 connection is specific to Oxygen. You would need a regulator with a CGA 580 (Argon) or CGA 320 (CO2) connection for those gases.

The inlet is CGA 540 (Oxygen) and the outlet is 9/16"-18 Right Hand (Standard Oxygen Hose).

Yes, Miller Smith equipment typically comes with the True Blue Warranty. Check the specific warranty card included for duration, often 3 years for regulators.

The body is constructed from brass bar stock and is nickel-plated for protection.

No, it is designed for non-corrosive, inert, or oxygen service only. It is not recommended for corrosive applications.
