MW-041 - 1.5-Inch High Pressure Regulator Gauge 4000 PSI Back Mount

Reliable High-Pressure Monitoring for Welding Regulators

Ensure your welding operations run safely and efficiently with this premium 1.5-inch High Pressure Gauge. Designed specifically for the demanding environment of industrial welding, this gauge is calibrated to read up to 4000 PSI, making it the perfect replacement for the "contents" side of your gas regulator. Whether you are monitoring Oxygen, Argon, or other inert gas cylinders, accurate pressure readings are critical for knowing exactly how much gas remains in your tank before starting a long job.

The gauge features a standard 1/8-inch NPT back mount connection, which is the industry standard for most compact and medium-duty welding regulators. Its 1.5-inch diameter face is compact enough to stay out of the way while providing clear, legible markings that allow operators to check cylinder pressure at a glance. A broken or stuck gauge can lead to unexpected downtime or unsafe operating conditions; replacing it is a quick and cost-effective maintenance step that restores full functionality to your equipment.

Constructed with durability in mind, this gauge withstands the vibrations and minor impacts common in workshops and job sites. It is an essential spare part for any welder's toolkit, ensuring that a cracked lens or bent needle doesn't halt production. Compatible with a wide range of regulator brands, this high-pressure gauge offers peace of mind and precision performance.
