999519 - 2-Inch Oxygen Cylinder Content Gauge 0-4000 PSI Steel Case

Precision High-Pressure Monitoring for Industrial Regulators

The ESAB 999519 Gauge is a critical component for maintaining the safety and efficiency of gas regulation systems in industrial welding and cutting operations. Designed to monitor high-pressure cylinder contents, this gauge features a measurement range of 0 to 4000 PSI, making it suitable for standard oxygen cylinders and various inert gas vessels. The 2.00-inch dial face provides a balance between compactness and readability, allowing operators to quickly assess remaining gas levels without straining to read the scale.

Constructed with a durable steel case, this gauge is engineered to resist the mechanical impacts and environmental stressors common in heavy-duty fabrication environments. The internal mechanism is calibrated to deliver consistent accuracy, ensuring that gas supply management is precise and reliable. The unit utilizes a Lower Back Mount (LBM) configuration, which is the industry standard for most gas regulators, facilitating seamless replacement and integration into existing setups. The connection is typically a standard NPT thread, ensuring a leak-tight seal when properly installed with appropriate thread sealant or tape.

Color-coded green, this gauge follows standard industry safety protocols, visually identifying it for use with Oxygen or compatible inert gases. This visual cue is essential for safety in multi-gas environments, helping to prevent cross-connection hazards. Whether used for maintenance, repair, or operations (MRO) or as a direct OEM replacement, the ESAB 999519 ensures that your gas delivery systems remain operational and safe. Regular inspection and replacement of damaged gauges are vital for compliance with safety standards and for the protection of personnel and equipment.

This gauge is not merely a replacement part; it is an investment in system integrity. Its robust build quality minimizes the frequency of replacements due to housing damage, while the clear markings reduce the likelihood of reading errors. It is compatible with a wide range of single-stage and two-stage regulators used in oxy-fuel cutting, MIG welding, and TIG welding applications.
