2.5-Inch Replacement Regulator Gauge 0-4000 PSI Oxygen/Inert

Upgrade Your Regulator's Readability

Is your regulator's high-pressure gauge cracked, stuck, or difficult to read? The Western Enterprises 2.5-Inch 4000 PSI Gauge is the perfect upgrade or replacement for your welding setup. Unlike the smaller 2-inch gauges found on many economy regulators, this 2.5-inch model provides a larger, clearer display, making it much easier to check your tank levels at a glance. Knowing exactly how much gas you have left is essential to avoid running out in the middle of a critical weld.

Universal Gas Compatibility

This gauge isn't just for one type of job. It is specifically designed and cleaned to be safe for Oxygen service, which is the highest safety standard for welding gauges. Because it is oxygen-clean, it is also perfectly safe to use on your MIG and TIG inert gas cylinders, including Argon, Helium, and Argon/CO2 mixes. This versatility makes it a "must-have" spare part for your shop. If you swap between different processes, having a reliable high-pressure gauge that works on all your tanks simplifies your maintenance.

Easy Installation and Durability

Installing this replacement gauge is straightforward. It features a standard 1/4-inch NPT bottom thread, which is the common size for medium-to-heavy-duty regulators (always check your existing gauge thread size, as some smaller regulators use 1/8-inch). The tough metal case protects the internal brass mechanisms from the bumps and knocks of daily shop life. With a range of 0-4000 PSI, it covers the full pressure of standard industrial cylinders (usually 2200-2600 PSI) with plenty of headroom for safety. Keep your equipment in top shape and ensure you never second-guess your gas supply again.
