OVERVIEW

Replace Your Broken Regulator Gauge with Confidence

Is the gauge on your oxygen or argon regulator cracked, stuck, or just plain impossible to read? A faulty high-pressure gauge isn't just an annoyance—it's a guessing game you don't want to play when you're in the middle of a job. This 2-inch Replacement Pressure Gauge is the perfect fix to get your gear back in top shape. Rated for up to 4000 PSI, it is designed to tell you exactly how much gas is left in your tank so you never run out unexpectedly.

This gauge is built for the "High Pressure" side of your regulator—that's the side that connects directly to the cylinder. It works perfectly with Oxygen as well as inert shielding gases like Argon, Nitrogen, and Helium. If you are running a MIG or TIG setup, or an Oxy-Fuel cutting torch, this is likely the part you need. It features a standard 1/4-inch thread that screws right into the body of almost any standard regulator (Victor, Harris, Miller, Lincoln, etc.).

Don't let a $20 part hold up a $2000 project. Swapping out a gauge is a simple maintenance task that keeps your equipment safe and professional. The clear white face with black markings makes it easy to check your levels from a distance. Plus, it comes cleaned and ready for oxygen service right out of the box, so you don't have to worry about safety compatibility.

FAQ

This is a high-pressure gauge (4000 PSI) designed to measure the tank (cylinder) pressure.

Most likely, yes. The 1/4" NPT thread is the industry standard for 2-inch gauges on almost all major regulator brands.

No. Acetylene gauges require different internal materials and a much lower pressure range (usually 400 PSI max). This gauge is for Oxygen and Inert gases only.

It is recommended to use a small amount of PTFE tape or oxygen-safe thread sealant on the threads, ensuring none gets inside the gas path.

Yes, this gauge is cleaned for oxygen service, meaning it is free of oils and hydrocarbons that could react dangerously with pure oxygen.

It refers to the diameter of the gauge dial face, which is 2 inches.

Yes, provided the regulator is designed for inert gas/CO2. However, CO2 liquid/gas equilibrium pressure is typically around 800-900 PSI, which will read on the lower end of this 4000 PSI scale.

Exceeding the rated 4000 PSI can permanently damage the Bourdon tube, causing the gauge to read inaccurately or fail. Always ensure your system pressure does not exceed the gauge limit.
