OVERVIEW

Consistent Oxygen Flow for Professional Fabrication

For welders and fabricators who demand consistency, the Miller Smith 123-00-08 Silverline Series regulator is a reliable workhorse. If you have ever struggled with your flame changing or flow dropping as your oxygen tank gets low, you know the frustration of single-stage regulators. This two-stage regulator solves that problem completely. 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 nearly empty. This means you can focus on your cut or weld without constantly stopping to tweak your regulator settings.

Built to last, this regulator features a solid brass body that can take the bumps and knocks of a busy shop. The large, 2-1/2 inch gauges are easy to read at a glance, even from a distance, so you always know your tank status and line pressure. The 250 PSI delivery range gives you plenty of power for heavy-duty cutting applications or high-flow requirements. It connects directly to standard Oxygen cylinders via a CGA 540 fitting.

One of the standout features is the Sure-Seat technology. Regulators often fail because dust or grit gets into the seat, causing leaks or 'creep.' Miller Smith has designed this unit with a filtered seat that traps contaminants before they can do damage. This means fewer repairs, less downtime, and a regulator that stays accurate for years. Whether you are setting up a cutting station in a maintenance shop, a laboratory gas supply, or a general fabrication line, this regulator provides the precision and durability professional tradespeople expect from the Miller Smith brand.

FAQ

A two-stage regulator reduces cylinder pressure in two steps, which keeps the delivery pressure constant even as the cylinder empties. Single-stage regulators require manual adjustment as the tank pressure drops.

This specific model comes with a CGA 540 inlet connection, which is the standard fitting for Oxygen cylinders.

This regulator can deliver pressures up to 250 PSI.

It features a 1/4" FNPT (Female National Pipe Thread) outlet, allowing for custom fittings or hard piping connections.

No, the CGA 540 fitting is specific to Oxygen. Argon uses CGA 580 and CO2 uses CGA 320. Using adapters is generally discouraged for safety and contamination reasons.

Yes, it includes a preset safety relief valve that vents to the atmosphere if pressure exceeds safe limits.

It is rated for a maximum inlet pressure of 3500 PSI.

Yes, the body and bonnet are machined from rugged brass bar stock, providing excellent durability and corrosion resistance.
