999437 - ESAB 2.5-Inch Replacement Regulator Gauge - 0-30 PSI Acetylene

Keep Your Pressure in Check with ESAB

When you are in the middle of a welding project, the last thing you want to second-guess is your gas flow. A cracked or stuck gauge isn't just annoying; it can be a safety hazard and mess with your weld quality. That's where this ESAB 2.5-Inch 30 PSI Gauge comes in handy. It is designed as a direct replacement for those low-pressure delivery gauges found on many standard regulators.

This particular model features a 0-30 PSI range, which is the sweet spot for monitoring delivery pressure on fuel gases like Acetylene. You will often see a red line on these gauges indicating the maximum safe working pressure (usually 15 PSI for Acetylene), helping you stay within safe operating limits at a glance. The "LBM" in the name stands for Lower Back Mount, meaning the connection threads stick out of the back of the case near the bottom, rather than straight down from the bottom rim. This is crucial for fitting into specific regulator bodies or panel mounts.

Constructed with a durable plastic case ("PLA"), this gauge resists corrosion and is lightweight. Whether you are refurbishing an old regulator or fixing a gauge that took a hit in the shop, this ESAB unit provides the clarity and reliability you need to get back to work safely.

• Perfect Fit: 2.5-inch dial size is standard for many industrial regulators.


• Safety First: 30 PSI scale is ideal for low-pressure fuel gas monitoring.
