Smith GA134-03 2" Acetylene Regulator Gauge 0-30 PSI

Reliable Replacement: Smith 2" Acetylene Gauge (0-30 PSI)

A cracked or broken gauge on your regulator isn't just an annoyance—it's a safety hazard. The Smith Equipment GA134-03 is the industry-standard replacement for your low-pressure acetylene gauge. Whether you dropped your regulator or the old gauge has simply become unreadable over time, this 2-inch replacement restores the accuracy and safety you need to keep welding.

Safety First with the Red Zone
Acetylene is unstable at pressures above 15 PSI. This gauge takes the guesswork out of safety with a clearly marked "Red Zone" on the dial. This visual warning ensures you never accidentally crank your delivery pressure into the danger zone. The 0-30 PSI range gives you fine-tuned control over your flame, allowing for precise adjustments when welding or cutting thin materials.

Built for the Shop
Welding shops are tough environments. That's why Smith built this gauge with a shatterproof polycarbonate lens rather than standard glass. It can take a knock without sending shards flying. The lens also features a protective lip to keep the face from getting scratched or damaged if the regulator is set face-down. Inside, a precision watch-type movement keeps the needle steady, so you aren't squinting at a bouncing needle when trying to set your flow.

Universal Fit
While it's a genuine Smith part, this gauge is designed to be a universal problem solver. It features a standard 1/4" NPT thread, which is the most common port size for industrial regulators. This means it fits most Miller, Victor, Harris, and generic regulators just as well as it fits Smith equipment. It comes in a convenient slider-pak, ready to thread in and get you back to work.
