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

Reliable Replacement Gauge for Welding Regulators

Maintain the precision of your gas delivery system with the ESAB 978153 Replacement Pressure Gauge. Designed for professional welders and fabricators, this gauge provides clear, accurate readings of gas pressure, which is essential for achieving high-quality welds and ensuring operational safety. A broken or inaccurate gauge can lead to inconsistent gas flow, porosity in welds, or dangerous over-pressure situations. This replacement unit is built to the high standards expected from ESAB, ensuring longevity and reliability in tough shop environments.

Technical Specifications and Design
The gauge features a 2-inch (50mm) dial face, a common size that fits perfectly on most industrial gas regulators without obstructing other controls. The scale is printed with high-contrast numerals, displaying pressure from 0 to 400 PSI and 0 to 2800 kPa. This specific pressure range is ideal for the "delivery" or "working pressure" side of many regulators, allowing for fine-tuning of the gas output to the torch. The Center Back (CB) mount design allows for straightforward installation into the regulator body, orienting the face towards the operator for easy monitoring.

Installation and Compatibility
Replacing a gauge is a simple maintenance task that can significantly extend the life of your regulator. The ESAB 978153 is compatible with any regulator requiring a 2-inch gauge with a center back mount and a 400 PSI range. It is suitable for use with non-corrosive gases typically used in welding, such as Argon, CO2, Helium, Nitrogen, and Oxygen (ensure the regulator is oxygen-clean if used for oxygen service). The brass stem ensures a durable thread engagement that resists galling and corrosion.

Why Replace Your Gauge?

• Readability: Old gauges often become clouded or scratched; a new face ensures you don't misread critical values.
• Accuracy: Dropped regulators or pressure spikes can de-calibrate internal mechanisms. A new gauge restores trust in your settings.
• Compliance: Safety inspections often require all gauges to be intact and functional.

Invest in the ESAB 978153 to ensure your welding operations remain safe, precise, and professional.
