ESAB 2.5-Inch High Pressure Regulator Gauge 4000 PSI Blue Face

Clear Readings for Your Gas Supply

There is nothing more frustrating than running out of gas in the middle of a critical weld because you couldn't read your tank gauge properly. The ESAB 2.5-inch 4000 PSI Gauge is the reliable replacement you need to keep your eyes on your gas supply. Designed for the "contents" side of your regulator, this gauge tells you exactly how much pressure is left in your tank, from a full cylinder all the way down to empty. With a max reading of 4000 PSI, it handles the pressure of standard oxygen and inert gas cylinders with ease.

This isn't just a generic throw-away part; it's built with the welder's environment in mind. The 2.5-inch face is larger than the tiny gauges found on cheap hobbyist regulators, meaning you don't have to squint to see where your needle is pointing. The blue background isn't just for looks—it helps the markings pop so you can check your levels with a quick glance across the shop. Plus, the lens is made from tough plastic, so if you accidentally knock your regulator off the bench or bang it against a tank, you won't be dealing with dangerous broken glass shards.

Installation is straightforward for anyone familiar with regulator maintenance. It features a standard Lower Back Mount (LBM) connection that screws into the back of the regulator body. If your old gauge is sticking, has a cracked face, or simply won't return to zero, swapping it out for this ESAB unit is a quick fix that restores your gear to safe working order. Don't guess how much Argon or Oxygen you have left; trust a gauge that is built to perform.

Whether you are outfitting a rig for the field or maintaining station drops in a fabrication shop, reliable gauges are the first line of defense against downtime. This gauge fits many standard heavy-duty regulators and provides the durability you expect from a top-tier brand like ESAB. Keep your arc lit and your gas flow managed with equipment that works as hard as you do.
