GA136-03 - Smith Equipment 2" Flow Gauge 0-50 CFH / 0-25 LPM

Smith Equipment GA136-03 2-Inch Replacement Flow Gauge

The Smith Equipment GA136-03 is a high-quality replacement flow gauge designed for precision and durability in industrial gas delivery systems. Engineered to meet Smith Equipment's rigid quality standards, this gauge provides accurate flow readings for shielding gases used in welding processes such as MIG and TIG. The unit features a dual-scale dial face that displays flow rates in both Cubic Feet per Hour (0-50 CFH) and Liters Per Minute (0-25 LPM), accommodating various operational standards and preferences without the need for conversion charts.

Constructed with a robust steel case finished in black, the GA136-03 is built to withstand the rigors of daily industrial use. The internal mechanism utilizes a precision watch-type movement, ensuring that flow readings remain consistent and accurate over time. A critical safety and durability feature is the one-piece polycarbonate crystal. Unlike traditional glass lenses, this shatter-resistant material eliminates the risk of breakage from accidental impacts, protecting both the gauge face and the operator. The crystal is secured with a 1/4-turn ring and features a protective lip that further guards against surface damage.

Installation is straightforward and universal for most standard equipment. The gauge is equipped with a 1/4-inch NPT male brass bottom connection, making it compatible with all major brands of gas pressure regulators that utilize 1/4-inch FNPT gauge inlet threads. Whether replacing a damaged unit on a Smith regulator or retrofitting another brand, this UL Listed component ensures reliable performance. The high-visibility cupped steel face and clear, high-contrast markings allow operators to monitor gas flow easily from a distance, ensuring optimal shielding gas coverage and weld quality.
