ESAB 2-Inch Acetylene Cylinder Gauge 0-400 PSI Lower Back Mount

Reliable Replacement Gauge for Acetylene Regulators

Keep your welding setup running safely and efficiently with the ESAB 999517 Replacement Pressure Gauge. A broken or unreadable gauge on your regulator isn't just an annoyance—it's a safety hazard and a productivity killer. This high-quality replacement gauge is designed to get your equipment back in top shape, giving you clear, accurate readings of your acetylene cylinder pressure so you never run out of gas unexpectedly in the middle of a cut or weld.

The gauge features a durable steel case that stands up to the knocks and bumps of daily shop life. Unlike cheaper plastic alternatives, this steel housing protects the sensitive internal movements, ensuring your gauge lasts longer even in tough conditions. The 2-inch dial is the perfect size for standard regulators, offering large, easy-to-read numbers without adding unnecessary bulk to your setup. With a range of 0-400 PSI, it is specifically calibrated to read the high-pressure content of acetylene tanks, giving you a precise indication of how much fuel is left.

Safety is paramount in welding, and this gauge helps you maintain it. The red color-coding instantly identifies it as a fuel gas gauge, preventing dangerous mix-ups with oxygen equipment. The Lower Back Mount (LBM) design makes installation a breeze—simply unscrew your old, damaged gauge, apply some thread sealant to the new one, and screw it into place. It’s a quick fix that restores the functionality of your expensive regulator for a fraction of the cost of buying a new unit.
