GA043-07 - Smith Equipment 2.5-Inch High Pressure Regulator Gauge, 0-4000 PSI, Brass Case

Precision High-Pressure Monitoring for Industrial Gas Regulators

The Smith Equipment GA043-07 is a professional-grade replacement pressure gauge engineered to meet the rigorous demands of industrial gas regulation. Manufactured in accordance with Smith's strict quality standards, this gauge is designed to provide reliable, accurate readings for high-pressure applications, specifically for monitoring cylinder contents up to 4000 PSIG. It is an essential component for maintaining the safety and efficiency of oxy-fuel and inert gas welding setups.

At the core of this gauge is a precision watch-type movement mechanism. Unlike lower-quality alternatives that may suffer from needle flutter or hysteresis, the Smith GA043-07 delivers smooth, consistent indication of cylinder pressure. This accuracy is critical for operators who need to gauge remaining gas levels precisely to plan their workflow and avoid unexpected downtime. The face of the gauge features a high-visibility cupped steel design with clear, distinct markings in both PSI and Bar, allowing for universal usage across different measurement standards.

Durability is a key focus of the GA043-07's design. The internal components are housed within a rugged brass case that resists corrosion and mechanical stress. The lens is crafted from a one-piece polycarbonate crystal, which is significantly more shatter-resistant than traditional glass. This protective lip design helps prevent damage to the face if the regulator is tipped or impacted, a common occurrence in busy workshops. Furthermore, the gauge is UL Listed, ensuring it meets established safety protocols for high-pressure gas equipment.

Installation is straightforward with the standard 1/4-inch NPT male bottom mount connection. This thread size is the industry standard for most medium-to-heavy-duty gas regulators, making the GA043-07 a versatile service part for mixed-brand fleets. Whether used on oxygen, argon, nitrogen, or helium regulators, this gauge restores the functionality and safety of your gas control equipment.
