999515 - ESAB 2-Inch Acetylene Delivery Gauge 0-30 PSI

Precision Monitoring for Fuel Gas Systems

The ESAB 999515 is a high-quality replacement pressure gauge designed specifically for industrial gas regulation applications. Engineered with a 2.00-inch diameter dial, this gauge provides clear and accurate readings for low-pressure delivery systems. The unit features a scale ranging from 0 to 30 PSI, making it the ideal choice for monitoring the delivery pressure of acetylene and other fuel gases where precise low-pressure control is critical for safety and process integrity. The gauge is constructed with a durable steel case (STL), ensuring resilience against the mechanical impacts and environmental conditions typical of industrial welding environments.

This model utilizes a Lower Back Mount (LBM) configuration, which is the industry standard for most gas regulators, allowing for a streamlined integration into existing equipment setups. The connection is typically a standard 1/4-inch NPT thread, compatible with a wide range of Victor and ESAB regulators, as well as other major brands utilizing standard port sizes. The internal mechanism is designed to provide consistent repeatability and accuracy, minimizing the risk of pressure drift that can affect flame characteristics during oxy-fuel cutting or welding processes.

Safety is paramount in gas distribution, and the ESAB 999515 incorporates visual cues to support safe operation. The face of the gauge is color-coded red, a universal standard in the welding industry to denote fuel gas service (as opposed to green for oxygen). This visual distinction helps prevent cross-connection errors during maintenance and allows operators to quickly identify the gas service line at a glance. The 0-30 PSI range is specifically calibrated to offer high resolution in the working range of acetylene, which generally operates below 15 PSI, ensuring operators can fine-tune their settings with confidence.

Maintenance personnel and procurement specialists looking for reliable MRO components will find this gauge to be a cost-effective solution for extending the lifecycle of expensive regulator equipment. Rather than replacing an entire regulator assembly due to a cracked lens or stuck needle, installing the ESAB 999515 restores full functionality and safety compliance. Its robust construction and adherence to industrial standards make it a dependable component for any compressed gas inventory.
