19077 - 2.5-Inch Replacement Regulator Gauge, 0-1000 PSI, Brass LBM

Fix Your Regulator with a Reliable 1000 PSI Gauge

There is nothing more frustrating in a busy fabrication shop than a regulator with a smashed or unreadable gauge. Not only is it a safety hazard to guess your pressure settings, but it also leads to poor weld quality and inconsistent gas flow. The 2.50-inch 1000 PSI Replacement Gauge is the perfect solution to get your equipment back in top shape. Designed as a direct replacement for many standard welding and industrial regulators, this gauge features a Lower Back Mount (LBM) connection that fits seamlessly into your existing regulator body.

This gauge is built tough for the shop environment. It features a solid brass connection and internal mechanism, which resists corrosion and stands up to the vibration of a working shop. The 0-1000 PSI range is versatile; it is commonly used for reading the tank pressure on CO2 cylinders (which typically sit around 800-900 PSI) or for high-pressure delivery readings on heavy-duty manifold systems. The 2.5-inch dial is slightly larger than the compact gauges found on cheap regulators, giving you a big, clear picture of your gas levels. The white background with bold black numbers makes it easy to check your pressure at a glance, even through a scratched welding helmet lens or from across the bench.

Installation is straightforward. Simply remove your old, damaged gauge (ensure the system is fully depressurized first!), apply a small amount of appropriate thread sealant to the new gauge's brass threads, and thread it in. Remember to always use a wrench on the brass square at the base of the stem—never tighten a gauge by twisting the case, as this can ruin the calibration. Once installed, this gauge provides reliable, steady readings that let you focus on laying beads rather than worrying about your gas supply.

Don't let a broken gauge compromise your safety or your work quality. Whether you are maintaining a fleet of MIG welders, setting up a TIG station, or managing a bulk gas manifold, having a clear, accurate pressure reading is non-negotiable. This 1000 PSI brass gauge offers the durability and clarity you need to keep your shop running smoothly and safely.
