OVERVIEW

Reliable Precision for Your Shop: Miller Smith Silverline Regulator

When your work demands consistency, the Miller Smith Silverline 121-00-08 Two-Stage Regulator delivers. Designed for professionals who cannot afford to constantly tweak their settings, this regulator takes the hassle out of gas control. Unlike standard single-stage regulators that allow delivery pressure to creep up as your tank gets low, this two-stage workhorse maintains a rock-steady flow from the moment you crack the valve until the cylinder is empty. This means you can focus entirely on your task—whether it's welding, cutting, or laboratory work—without worrying about fluctuating gas output affecting your quality.

Built tough for the real world, the Silverline series features a solid brass body machined from bar stock, not a cheap casting. This ensures it can handle the bumps and knocks of a busy shop environment. The body and gauges are plated for extra protection against corrosion, keeping your equipment looking and working like new for longer. Inside, Miller's Sure-Seat technology filters out harmful particles that often cause regulators to fail prematurely, giving you a tool that lasts. The large, easy-to-read 2-1/2 inch gauges let you check your levels at a glance, so you're never caught off guard by an empty tank.

This specific model comes equipped with a CGA 540 connection, making it ready for standard Oxygen cylinders right out of the box. It offers a delivery range of 0-60 PSI, perfect for a wide variety of general-purpose applications. The outlet is a standard 1/4" Female NPT, giving you the flexibility to attach whatever hose barb or fitting your specific setup requires. Whether you are outfitting a maintenance bench, a testing rig, or a fabrication station, the Miller Smith 121-00-08 offers the perfect blend of industrial durability and laboratory-grade precision.

FAQ

A two-stage regulator, like the Miller Smith 121-00-08, reduces cylinder pressure in two steps. This ensures the delivery pressure remains constant even as the cylinder pressure drops, whereas a single-stage regulator may require frequent adjustment as the tank empties.

CGA 540 is the standard connection for Oxygen cylinders in the United States. While the Silverline series supports other gases, this specific SKU is fitted for Oxygen.

Not directly. This unit comes with a CGA 540 nut and nipple for Oxygen. To use it with CO2 (CGA 320) or Argon (CGA 580), you would need to change the inlet connection, which should only be done by a certified technician, or purchase the correct model for that gas.

The outlet is a 1/4" Female NPT (National Pipe Taper) port. You will need to install a compatible fitting or hose barb to connect your gas hose.

The Miller Smith 121-00-08 is rated for a maximum inlet pressure of 3500 PSIG.

Yes, it includes a preset safety relief valve that vents to the atmosphere if the pressure exceeds safe limits. Note that this makes it suitable only for non-hazardous gases.

This regulator is designed to deliver gas at pressures ranging from 0 to 60 PSIG.

While rugged, it is a precision instrument. It can be used outdoors but should be protected from direct exposure to rain, snow, and extreme contamination to maintain the gauge and seat integrity.
