The ESAB 2.50-inch 4000 PSI Gauge is a critical component for maintaining the safety and efficiency of industrial gas regulation systems. Designed specifically for the high-pressure side of welding regulators, this gauge provides accurate readings of cylinder contents, allowing operators to monitor gas supply levels with precision. The gauge features a substantial 0 to 4000 PSI scale, making it suitable for use with standard oxygen cylinders as well as various inert gas vessels such as Argon, Helium, and Nitrogen mixtures typically found in MIG and TIG welding applications.
Engineered with a Lower Back Mount (LBM) connection, this unit is designed to thread directly into the rear of compatible regulator bodies, maintaining a streamlined profile that does not interfere with the adjustment handle or outlet connections. The internal mechanism is built to withstand the sudden pressure spikes often associated with opening cylinder valves, although standard safety protocols regarding slow valve opening should always be observed. The "PLA" designation indicates a durable plastic lens, which offers significant advantages over glass in industrial settings by resisting shattering upon impact, thereby enhancing operator safety.
Visual clarity is paramount in process control. This model utilizes a distinctive blue faceplate which provides high contrast against the white or black markings of the pressure scale. This design consideration ensures that the needle position is easily discernible even from a distance or in low-light workshop conditions. Whether used as a direct OEM replacement for worn ESAB equipment or as a high-quality upgrade for compatible third-party regulators, this gauge delivers the reliability and accuracy required for professional fabrication, maintenance, and repair operations.
Proper maintenance of gas equipment is essential for shop safety. A compromised gauge—whether it has a bent needle, cracked face, or stuck movement—can lead to uncertainty about gas reserves or, worse, potential leaks. Installing this robust ESAB gauge restores full functionality to the regulator, ensuring that the high-pressure stage is monitored correctly. Its 2.5-inch diameter strikes the perfect balance between compactness for portability and size for readability, making it a standard choice for heavy-duty industrial regulators.
