A broken or inaccurate gauge on your welding regulator isn't just an annoyance—it's a safety hazard and a quality control issue. The Smith Equipment GA138-03 Replacement Gauge is the professional's choice for restoring the functionality of your gas equipment. Designed to fit a wide variety of regulators, this 2-inch gauge is perfect for monitoring delivery pressure up to 400 PSIG. Whether you are working with oxygen, argon, or mixed gases, having a clear and accurate reading of your output pressure is essential for maintaining a stable arc and a clean cut.
Welding shops are tough places, and equipment gets banged around. That's why Smith Equipment designed this gauge with a rugged steel case and a shatterproof polycarbonate lens. Unlike cheap plastic replacements or glass-faced gauges that crack easily, the GA138-03 can withstand the daily rigors of industrial use. The lens also features a unique protective lip that guards the face against direct impact, ensuring your gauge stays readable for longer. The high-contrast dial face makes it easy to check your settings at a glance, even in low-light conditions or through a welding helmet visor.
One of the best features of the GA138-03 is its versatility. It utilizes a standard 1/4-inch NPT brass thread, which is the industry standard for most gas regulators. This means you can use this high-quality Smith gauge to upgrade or repair regulators from virtually any major brand, not just Smith Equipment. Installation is simple: just apply a small amount of PTFE tape (approved for oxygen use if applicable) to the threads and screw it into the gauge port. It's an affordable, high-value upgrade that extends the life of your expensive regulator equipment.
Never compromise on safety when dealing with compressed gases. This gauge is U.L. Listed, giving you peace of mind that it has been tested and approved for safe operation under pressure. The precision movement ensures that the needle doesn't stick or jump, giving you a true reading of your line pressure every time you open the cylinder.
