GA143-03 - Smith Equipment 2-Inch Replacement Regulator Gauge 0-100 PSI

Precision Monitoring with the Smith GA143-03 Pressure Gauge

The Smith Equipment GA143-03 is a high-quality replacement pressure gauge designed to restore the functionality and safety of your gas regulation equipment. Engineered for industrial environments where accuracy and durability are paramount, this gauge features a robust 2-inch diameter steel case that protects the internal mechanisms from external impacts and shop wear. The unit is specifically calibrated for a delivery pressure range of 0-100 PSIG, making it an ideal component for monitoring the output pressure of various shielding gases, oxygen, or other industrial gases used in welding and cutting processes.

At the heart of the GA143-03 is a watch-type precision movement. Unlike standard gauges that may suffer from needle flutter or calibration drift, this mechanism ensures smooth, accurate readings that allow operators to fine-tune gas flow with confidence. The high-visibility cupped steel face features clear, distinct markings, reducing the likelihood of reading errors even in dimly lit workshop environments. This attention to detail in the dial design supports better process control and quality assurance in sensitive applications.

Durability is further enhanced by the inclusion of a one-piece polycarbonate crystal. This shatterproof material is far superior to standard glass, eliminating the risk of dangerous fragmentation if the gauge is accidentally struck. The crystal is designed with a protective lip that helps shield the gauge face from damage. The gauge connects via a standard 1/4-inch MNPT brass inlet nipple, ensuring compatibility with virtually all major brands of gas pressure regulators that utilize 1/4-inch FNPT inlet threads. This universal fitment makes the GA143-03 a versatile stock item for maintenance departments and repair facilities. U.L. Listed for safety, this gauge represents a reliable solution for maintaining the integrity of your gas delivery systems.
