OVERVIEW

Precision Pressure Monitoring for Industrial Gas Systems

The ESAB 19137 is a high-quality replacement pressure gauge designed to restore functionality and safety to your gas regulation equipment. Accurate pressure monitoring is critical in industrial gas applications, not only for process consistency but also for operator safety. This gauge features a calibrated range of 0 to 400 PSI, making it particularly suitable for monitoring Acetylene cylinder pressure (where full cylinders typically read ~250 PSI) or for specific high-pressure delivery applications requiring this intermediate range.

Constructed with a 2.5-inch diameter dial, this gauge provides a larger viewing area than standard 2-inch gauges, reducing eye strain and allowing for quick checks from a distance. The face is finished in a bright white with distinct, high-contrast markings, ensuring that pressure readings are legible even in workshops with variable lighting conditions. The scale is designed to provide precise feedback on gas levels, helping operators manage cylinder changeouts efficiently and avoid downtime caused by running out of gas unexpectedly.

The unit utilizes a Lower Back Mount (LBM) connection, the industry standard for most gas regulators, ensuring seamless integration with equipment from ESAB, Victor, and other major manufacturers. The casing is crafted from durable plastic (PLA), which offers excellent resistance to workshop environments, including resistance to corrosion and minor impacts. Whether you are maintaining a fleet of welding carts or repairing a single station, this gauge delivers the reliability required for professional gas distribution systems.

Proper maintenance of gas equipment involves regular inspection of gauges for physical damage or calibration drift. A compromised gauge can lead to leaks or inaccurate pressure delivery. Replacing a damaged unit with the ESAB 19137 ensures your system remains compliant with safety standards and operates at peak efficiency.

FAQ

Most 2.5-inch gauges, including this model, typically utilize a 1/4-inch NPT thread. Please verify your regulator's port size before ordering.

While the pressure range is compatible with oxygen delivery, all gauges used for oxygen must be cleaned specifically for oxygen service to prevent combustion. Check the packaging for 'Use No Oil' markings.

Yes, a 0-400 PSI gauge is the standard 'High Pressure' (cylinder content) gauge for Acetylene regulators, as Acetylene cylinders are pressurized to approximately 250 PSI.

LBM stands for Lower Back Mount, meaning the threaded connection protrudes from the back of the gauge at the bottom (center), which is standard for panel and regulator mounting.

This specific model (PLA) features a durable plastic case, which is lightweight and resistant to corrosion.

Ensure the system is depressurized. Remove the old gauge using a wrench on the brass stem (never twist the case). Apply Teflon tape to the new gauge threads (avoiding the first thread) and tighten firmly.

Yes, provided your regulator accepts a 1/4" NPT thread and requires a 0-400 PSI range, this is compatible with Victor and most other major brands.

Exceeding the maximum scale can damage the internal bourdon tube, causing the gauge to become inaccurate or fail. Always choose a gauge range higher than your maximum operating pressure.
