999434 - ESAB 2.5-inch Replacement Regulator Gauge 0-100 PSI LBM

Precise Pressure Monitoring for Industrial Regulators

The ESAB 999434 is a high-quality replacement pressure gauge designed to restore functionality and safety to your gas regulation equipment. Accurate pressure monitoring is critical in welding and industrial applications to ensure consistent flow rates and process integrity. This gauge features a 2.50-inch diameter dial, which offers superior legibility compared to standard 2-inch gauges, allowing operators to verify settings quickly and accurately from a distance.

Engineered with a range of 0 to 100 PSI, this gauge is typically utilized for low-pressure delivery readings on regulators. The scale is calibrated to provide precise feedback on the output pressure being delivered to the torch or downstream equipment. The unit is constructed with a durable plastic (PLA) case, which provides a lightweight yet robust housing that resists corrosion and impact in shop environments. The internal mechanism is designed for reliability, ensuring that the needle movement is smooth and responsive to pressure changes without excessive flutter.

Installation is straightforward thanks to the Lower Back Mount (LBM) configuration, a standard orientation for many industrial gas regulators. This design allows the gauge to sit flush against the regulator body while facing the operator. Whether you are maintaining a fleet of welding carts or repairing a single station, the ESAB 999434 provides the OEM quality and fitment required for safe operation. Regular inspection and replacement of damaged gauges are essential safety practices; this unit ensures your equipment remains compliant and operational.
