0781-0043 - Victor SR250D-540 Medium Duty Oxygen Regulator, CGA-540, 5-125 PSIG

Reliable Precision with the Victor SR250D-540 Oxygen Regulator

For welders and fabricators who demand consistency and durability in their oxy-fuel equipment, the Victor SR250D-540 Medium Duty Oxygen Regulator is a proven choice. Part of the legendary SR 250 series, this regulator is designed to bridge the gap between light-duty portability and heavy-duty capacity, making it the perfect all-arounder for maintenance shops, fabrication floors, and construction sites. When you are handling oxygen cylinders for cutting or welding, you need a regulator that holds its pressure setting without constant tweaking, and the SR250D delivers exactly that.

Built to last, the SR250D-540 features a heavy-duty die-forged brass body that can withstand the accidental bumps and knocks of daily shop life. Unlike cheaper cast or plastic-composite alternatives, this brass construction ensures that threads remain true and the body remains leak-free. The regulator is equipped with a large, easy-to-turn T-handle that makes setting your pressure smooth and effortless, thanks to the internal Delrin bushing that reduces friction. Whether you are dialing in 5 PSIG for delicate work or 125 PSIG for thicker cutting applications, the control is precise and responsive.

Visibility and safety are paramount in welding applications. This Victor regulator sports two clear, 2-inch brass gauges that allow you to monitor your cylinder pressure and delivery pressure at a glance. The high-contrast faces are easy to read even in dimly lit work areas. Safety features include a sintered inlet filter that stops dirt and debris from entering the seat assembly—a common killer of regulators—and an external self-reseating relief valve that vents excess pressure if a malfunction occurs within the regulator body.

This model connects to standard oxygen cylinders with a CGA-540 valve and pairs perfectly with standard "R" grade or "T" grade oxygen hoses via its 9/16"-18 RH outlet. Whether you are cutting steel plate, brazing HVAC lines, or heating stubborn bolts, the Victor SR250D-540 provides the steady oxygen flow you need to maintain a clean, hot flame. Invest in Victor quality and experience the difference in your flame stability and equipment longevity.
