ESAB 2.5" Oxygen Delivery Gauge, 0-100 PSI, Lower Back Mount

Restore Your Regulator with the ESAB 100 PSI Gauge

Don't let a cracked or broken gauge slow down your fabrication projects. The ESAB Replacement Pressure Gauge (0-100 PSI) is the perfect solution for fixing your oxygen or inert gas regulator. Whether you dropped your regulator or the old gauge simply stopped reading accurately, this high-quality replacement part gets your equipment back in safe working order. Featuring a green face, it is instantly recognizable as a gauge suitable for oxygen service or low-pressure delivery readings.

This specific model features a 2.5-inch dial, which is slightly larger than the compact gauges found on hobbyist equipment. This extra size makes it significantly easier to read your flow settings from a distance, ensuring you can monitor your gas delivery without squinting. The scale reads from 0 to 100 PSI, covering the standard working pressure range for most oxy-fuel cutting, heating, and MIG/TIG welding applications.

Designed for the Welder's Needs

The connection is a Lower Back Mount (LBM), meaning the threaded stem comes out of the center of the back of the gauge. This is the correct mount for regulators where the gauges sit flush against the body. The casing is made from tough plastic, which offers a lightweight advantage and won't rust if your gear is stored in a damp truck or shop. It is designed to handle the vibrations and minor knocks associated with daily shop use.

Why Replace Your Gauge?

Welding with an inaccurate or broken gauge is like driving without a speedometer. You might be using too much gas (wasting money) or too little (compromising weld quality). By installing a fresh ESAB gauge, you ensure that your flow rates are precise, leading to cleaner cuts, better shielding, and professional results. Installation is straightforward—simply use a wrench on the brass stem (never twist the case) to seat it into your regulator using approved thread sealant.

• Easy to Read: 0-100 PSI scale is perfect for setting working pressure.
