The Smith Equipment GA138-03 is a high-quality replacement pressure gauge designed for industrial gas regulators. Engineered to meet Smith's rigid quality standards, this gauge provides a reliable solution for monitoring delivery pressure in welding, cutting, and heating applications. The unit features a dual-scale dial face that displays pressure in both Pounds Per Square Inch (PSIG) and Bar, with a range of 0-400 PSIG and 0-28 BAR respectively. This range is typically utilized for the delivery (low pressure) side of heavy-duty oxygen or inert gas regulators, or potentially for specific high-pressure applications depending on the equipment configuration.
Construction-wise, the GA138-03 is built for the harsh environment of metalworking shops. It houses a precision watch-type movement within a durable steel case, ensuring consistent accuracy and longevity. The internal mechanism is protected by a one-piece polycarbonate crystal. This crystal is not only shatter-resistant but also features a protective lip designed to prevent damage to the gauge face if the regulator is tipped or impacted. The inlet connection is a standard 1/4-inch Male National Pipe Thread (MNPT) brass nipple, located at the bottom of the case, making it compatible with the vast majority of industrial gas pressure regulators on the market that utilize 1/4-inch FNPT gauge ports.
Safety and compliance are paramount in high-pressure gas equipment. The Smith GA138-03 is U.L. Listed, verifying that it meets specific safety standards for compressed gas service. The high-visibility cupped steel face ensures that operators can easily read pressure settings from a distance, reducing the risk of error. Whether replacing a damaged gauge on a Smith regulator or another major brand, this component offers a seamless fit and reliable performance.
