Smith Equipment 2.5-Inch High Pressure Regulator Gauge, 0-4000 PSI, Brass Case

Restore Your Regulator with a Durable 4000 PSI Gauge

A broken or unreadable pressure gauge on your welding regulator isn't just an annoyance—it's a safety hazard and a productivity killer. The Smith Equipment GA043-07 Replacement Gauge is the perfect solution for welders looking to upgrade or repair their gas gear. Designed to measure high-pressure cylinder contents, this gauge reads from 0 to 4000 PSI, making it suitable for full oxygen, argon, and mixed gas cylinders.

One of the standout features of this gauge is its 2.5-inch diameter face. Larger than standard 2-inch gauges, it offers superior readability from a distance, allowing you to check your gas levels with a quick glance from your welding station. The dual-scale dial shows pressure in both PSI and Bar, so you're covered regardless of which metric your shop uses. The needle movement is smooth and precise, thanks to the high-quality internal mechanics, giving you confidence in your gas supply readings.

Shop environments are tough on equipment, which is why Smith Equipment built this gauge to last. The case is made from solid brass, not plastic or thin steel, providing a sturdy housing that stands up to daily wear and tear. The lens is made from shatterproof polycarbonate, eliminating the risk of dangerous broken glass if your regulator takes a knock. A protective lip around the crystal adds an extra layer of defense against impact damage.

Compatibility is key when looking for replacement parts. The GA043-07 features a 1/4-inch NPT male thread, which is the standard connection for the vast majority of industrial gas regulators on the market, including those from Miller, Victor, and Harris. Whether you are fixing an old favorite regulator or outfitting a new tank setup, this UL Listed gauge provides the safety, accuracy, and durability professional welders demand.
