999517 - ESAB 2-Inch Acetylene Cylinder Gauge 0-400 PSI Lower Back Mount

Technical Overview of the ESAB 999517 Pressure Gauge

The ESAB 999517 is a precision-engineered pressure gauge designed specifically for industrial gas regulation applications. This unit features a 2.00-inch diameter dial, providing an optimal balance between compact footprint and readability. Calibrated for a pressure range of 0 to 400 PSI, this gauge is primarily intended for monitoring cylinder contents on the high-pressure side of acetylene or fuel gas regulators. The scale is clearly marked to allow operators to assess tank levels instantly, ensuring workflow continuity and safety compliance.

Constructed with a robust steel case (STL), this gauge is built to endure the mechanical stresses and potential impacts common in welding workshops and field sites. The internal mechanism is protected against vibration and minor shocks, maintaining calibration accuracy over time. The connection interface is a Lower Back Mount (LBM), a standard configuration that ensures compatibility with a wide array of gas regulators. The threading is precision-cut to facilitate a secure, leak-proof seal when installed with appropriate thread sealant or tape.

Visual identification is critical in gas apparatus safety. This model features a red face or color-coding, which is the industry standard for fuel gases such as acetylene. This visual cue helps technicians quickly verify that the correct gauge is installed on the correct regulator, mitigating the risk of cross-contamination or improper equipment setup. Whether used for maintenance, repair, or operations (MRO) or as an OEM component, the ESAB 999517 delivers reliable performance in demanding environments.
