2.5-Inch Replacement Regulator Gauge 0-100 PSI Oxygen/Inert

Upgrade Your Regulator with a Clearer View

Is your regulator gauge cracked, stuck, or hard to read? The Western Enterprises 2.5-Inch Pressure Gauge (0-100 PSI) is the perfect upgrade or replacement for your welding setup. Most standard regulators come with smaller 2-inch gauges that can be difficult to squint at through a welding helmet or from across the bench. This larger 2.5-inch dial makes checking your working pressure significantly easier, helping you maintain the consistent gas flow needed for quality welds.

Designed for the Delivery Side

This gauge is calibrated up to 100 PSI, which is the ideal range for the "delivery" or "working pressure" side of your regulator. It allows for fine-tuning of your gas flow, whether you are TIG welding with Argon or cutting with Oxygen. The clear markings ensure you aren't guessing your settings. Because it is cleaned for Oxygen service, you can safely use it on your Oxygen regulators as well as for inert shielding gases like Argon/CO2 mixes, Helium, and Nitrogen.

Durable and Easy to Install

Welding shops are tough on equipment. That's why this gauge is built with a sturdy steel case and a brass internal movement that stands up to vibration and daily use. The 1/4" NPT threads are the industry standard for most larger regulators (check your existing gauge stem size to be sure; smaller regulators may use 1/8"). Simply apply a small amount of oxygen-safe PTFE tape to the threads, screw it into the outlet port of your regulator, and you're back in business with a reliable, easy-to-read display.
