978153 - ESAB 2-Inch Replacement Regulator Gauge 0-400 PSI Center Back

Precision Monitoring for Industrial Gas Regulators

The ESAB 978153 Pressure Gauge is a high-quality replacement component designed to restore the functionality and safety of your gas regulation equipment. In the world of welding and industrial gas distribution, accurate pressure monitoring is not merely a convenience—it is a safety necessity. This gauge features a standard 2-inch diameter dial, making it compact enough to fit most regulator bodies while remaining large enough to be read easily from a distance.

Engineered for durability, the gauge offers a pressure range of 0 to 400 PSI (pounds per square inch), which is also calibrated in the metric equivalent of 0 to 2800 kPa (kilopascals). This dual-scale capability ensures that operators can verify pressure settings according to their preferred unit of measurement without needing conversion charts. The 0-400 PSI range is typically utilized for monitoring delivery pressure (low pressure) on oxygen, inert gas, or CO2 regulators, ensuring that the flow to the torch or machine is consistent and within the optimal range for the specific welding process.

The connection type is a Center Back (CB) mount, which is the industry standard for most face-plate style regulators where the gauge screws directly into the back of the regulator body. The brass connection threads provide a secure, leak-free seal when installed correctly with appropriate thread sealant or tape. Whether you are replacing a cracked lens, a stuck needle, or a gauge that has lost its calibration, the ESAB 978153 offers a reliable solution to keep your equipment running smoothly.
