999444 - ESAB 2.5-Inch High Pressure Regulator Gauge 0-4000 PSI LBM

Technical Overview of the ESAB High Pressure Gauge

The ESAB 999444 is a precision-engineered pressure gauge designed for high-pressure industrial applications. Featuring a 2.50-inch diameter dial, this instrument provides clear and accurate readings for systems operating up to 4000 PSI. The scale is calibrated to deliver reliable metrics for cylinder content monitoring, making it an essential component for gas distribution systems and heavy-duty welding regulators. The unit utilizes a Lower Back Mount (LBM) configuration, which is the industry standard for most regulator bodies, ensuring seamless integration with existing equipment without the need for adapters.

Constructed with a durable plastic (PLA) case, this gauge is designed to withstand the rigors of industrial environments while maintaining a lightweight profile. The internal mechanism is built to resist vibration and shock, common in workshop settings, ensuring the needle remains stable and accurate over time. The 0-4000 PSI range is specifically suited for high-pressure gases such as Oxygen, Argon, Nitrogen, and Helium, covering the standard fill pressures of most industrial cylinders (typically 2000-3000 PSI) with ample headroom for safety and testing purposes.

Maintenance professionals and procurement specialists will appreciate the standardized specifications of this component. The clear lens provides excellent visibility of the dial face, which features high-contrast markings for quick assessment. Whether used for MRO (Maintenance, Repair, and Operations) stock or immediate repair of compromised regulators, the ESAB 999444 delivers the performance and reliability expected from a leading manufacturer in the welding and cutting industry.
