17772 - 1.5-Inch 4000 PSI Replacement Regulator Gauge, Lower Back Mount

Reliable Replacement for Your Regulator

A broken or sticking pressure gauge on your welding regulator isn't just an annoyance; it's a safety hazard and a productivity killer. If you can't tell how much gas is left in your tank, you risk running out in the middle of a critical weld, leading to porosity and rework. The ESAB 17772 4000 PSI gauge is the perfect solution for refreshing your tired gas equipment. Designed to replace the high-pressure "contents" gauge on most standard regulators, this unit reads up to 4000 PSI, covering the full pressure range of standard industrial gas cylinders.

Built for the Shop Environment
Welding shops are tough on equipment. That's why this gauge features a case made from ABS plastic. Unlike metal cases that can dent or rust, the ABS housing absorbs impacts and resists corrosion, keeping the internal mechanism safe. The 1.5-inch face is compact enough to stay out of the way but large enough to read clearly from a distance, thanks to its high-contrast white background. Whether you are welding with MIG, TIG, or Oxy-Fuel, knowing your input pressure is the first step to a quality weld.

Easy Installation
This gauge features a standard Lower Back Mount (LBM) connection, making it compatible with the majority of gas regulators on the market that use 1.5-inch gauges. Simply remove your old, damaged gauge, apply the appropriate thread sealant (PTFE tape or paste suitable for oxygen service if applicable), and thread this new unit in. It's a quick fix that restores the functionality and safety of your expensive regulator, saving you the cost of buying a whole new apparatus. Keep your arc on and your gas flow monitored with this reliable replacement part.
