OVERVIEW

Keep Your Regulator Reading True

A broken gauge is more than just an annoyance; it's a blind spot in your welding setup. The Miller GA075-15 Replacement Gauge is the reliable solution for getting your regulator back to factory specs. Designed specifically for the high-pressure side of your gas gear, this gauge reads up to 4000 PSI, letting you know exactly how much gas is left in your tank before you start a critical weld. There is nothing worse than running out of shielding gas in the middle of a bead because you couldn't read your bottle pressure—this gauge ensures you are always in the know.

Built to survive the daily grind of the welding shop, this unit features a tough 1.5-inch black steel case. It resists dents and dings better than standard brass or plastic gauges, ensuring it holds up when the regulator gets tossed into a gang box or bumped against a cart. The clear, easy-to-read dial displays pressure in both PSI and Bar, so you can verify your cylinder status at a glance, regardless of which measurement system you prefer. The compact size is perfect for regulators with tight rubber guards or metal cages, fitting seamlessly where larger 2-inch gauges might not.

This is a back-mount gauge, meaning the threaded connection sticks straight out the back, which is the standard configuration for the face of most welding regulators. It is compatible with a wide variety of Miller and Smith equipment used for Oxygen, Argon, and mixed gases. Don't risk leaks or guesswork with a cracked lens or stuck needle. Swap out your old gauge with this genuine Miller replacement and keep your focus on the arc, not on your equipment.

FAQ

This gauge is rated for a maximum pressure of 4000 PSI (and the equivalent in Bar).

This is a high-pressure gauge designed for the cylinder side (contents) to show how much gas is left in the tank.

The dial diameter is 1.5 inches.

No, this is a 4000 PSI gauge. Acetylene regulators require much lower pressure gauges (typically 400 PSI for contents) and have different internal construction for safety.

The case is made of black steel for durability.

It has a center back mount connection.

The gauge features a dual scale showing both PSI and Bar.

It fits most regulators that accept a 1.5-inch diameter, back-mount gauge with standard high-pressure threads, but it is specifically designed as a replacement for Miller and Smith equipment.
