3000554 - Harris Model 425 Heavy-Duty Oxygen Regulator 0-50 PSIG

Reliable Oxygen Control for the Professional Welder

When you are working in a busy shop or out on a job site, you need gear that can take a hit and keep on working. The Harris Model 425-50-540 Oxygen Regulator is built like a tank, featuring a solid forged brass body and bonnet that stands up to the knocks and bumps of daily industrial use. Unlike lighter-duty regulators that use plastic or die-cast zinc, the Model 425 feels substantial and is designed to last for years.

This single-stage regulator is perfect for cutting, welding, and brazing applications where you need a steady flow of oxygen up to 50 PSIG. The CGA 540 connection fits all standard industrial oxygen cylinders. One of the biggest frustrations with regulators is seat failure caused by dirt or shavings getting into the system. Harris solved this with their encapsulated seat technology, which includes a built-in filter to trap junk before it ruins the seat. This means you get a consistent flame and don't have to worry about your pressure creeping up while you work.

The large 2.5-inch gauges are clear and easy to read from a distance, so you can check your tank level and line pressure at a glance. The adjusting knob is sized right for gloved hands, making it easy to dial in the exact pressure you need. Whether you are running a cutting torch or a heating tip, this regulator delivers smooth, reliable flow. Plus, with Harris's 7-year warranty, you can trust that this tool is a long-term investment in your trade.
