2.5-Inch Low Pressure Regulator Gauge 0-200 PSI

Clear Readings for Precise Welds

Stop squinting at cracked or foggy gauges on your regulator. The ESAB 2.5-inch Replacement Gauge is designed to get your gear back in top shape so you can focus on laying beads. Whether you dropped your regulator or the old gauge just gave up the ghost, this 0-200 PSI unit is the perfect upgrade or replacement for the delivery side of your setup. The 2.5-inch face is slightly larger than the standard 2-inch gauges found on cheap regulators, giving you a much clearer view of your settings.

Setting your working pressure correctly is the first step to a good weld. If your pressure is too low, you get porosity; too high, and you're wasting gas and creating turbulence. This gauge covers the 0-200 PSI range, which is the sweet spot for checking the output pressure on most oxygen and inert gas regulators. The dial features crisp, easy-to-read numbers and likely includes green zone markings to help you quickly identify safe operating ranges. It connects via a standard Lower Back Mount, meaning it screws directly into the back of the gauge port on most regulator bodies.

Durability matters in the shop. While this gauge features a lightweight plastic case, it is built to withstand the vibrations and minor knocks of a working environment. It’s a straightforward, no-nonsense tool that does exactly what it's supposed to do: tell you exactly how much gas you are pushing. Don't let a broken gauge turn into a guessing game—swap it out and keep your parameters dialed in.

Installation and Compatibility

Installing this gauge is simple. Ensure your system is fully depressurized, remove the old gauge with a wrench, apply a small amount of Teflon tape (compatible with your specific gas service) to the threads of the new gauge, and screw it in until snug. The Lower Back Mount design keeps the profile clean and ensures the dial faces you when the regulator is mounted on the cylinder. It's compatible with most major brands of regulators requiring a 200 PSI delivery gauge.
