18694 - ESAB 50mm Steel Replacement Gauge 0-30 PSI

Precision Monitoring for Low-Pressure Applications

When you are working with fuel gases like acetylene, precision isn't just a luxury—it's a safety requirement. The ESAB 50mm Steel Pressure Gauge (0-30 PSI) is designed to give you that critical insight into your delivery pressure. Whether you are replacing a cracked face on an old regulator or building a custom manifold setup, this gauge offers the reliability you expect from a top-tier brand like ESAB.

The gauge features a compact 50mm (approximately 2-inch) dial, which is the industry standard for most portable and shop-floor regulators. The "RED STL" designation points to its robust steel case construction, providing superior protection against the accidental bumps and knocks that happen in a busy workshop. Unlike plastic-cased gauges that can crack or warp near heat sources, this steel housing ensures the internal mechanism stays protected and calibrated.

With a range of 0 to 30 PSI, this unit is specifically tailored for the "working" or "delivery" side of low-pressure regulators. This is particularly important for acetylene, where keeping pressure below 15 PSI is critical for stability. The scale is designed to be easily readable at a glance, allowing you to make quick adjustments to your torch flame without squinting at a cluttered dial. It installs easily into standard regulator ports, getting your equipment back up and running in minutes.
