ESAB 2.5-Inch Acetylene Cylinder Gauge 0-400 PSI

Keep Your Oxy-Fuel Gear Safe and Operational

A broken or unreadable gauge on your acetylene regulator isn't just an annoyance—it's a safety hazard. The ESAB 999441 Replacement Gauge is the perfect solution for getting your cutting torch or welding rig back in action. Designed to replace the high-pressure (contents) gauge on your regulator, it lets you know exactly how much gas is left in your tank so you don't run out in the middle of a cut.

Easy to Read, Built to Last
Squinting at a tiny, clouded gauge is a thing of the past. This unit features a large 2.5-inch face with crisp, high-contrast numbers. The 0-400 PSI scale covers the full pressure range of an acetylene cylinder. The bright red background serves as an instant visual reminder that you are working with fuel gas, adding an extra layer of safety to your setup.

Standard Fitment
This gauge uses a standard Lower Back Mount connection, making it compatible with many Victor and ESAB style regulators, as well as other brands using standard NPT ports. The plastic housing is tough enough to handle shop knocks while keeping the gauge affordable. Don't guess your gas levels—install a fresh ESAB gauge and weld with confidence.
