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

Reliable Replacement Gauge for Gas Regulators

When a regulator gauge fails, it can bring your welding operations to a halt or, worse, lead to inconsistent gas flow that compromises weld quality. The Smith Equipment GA143-03 2-Inch Replacement Gauge is the professional's choice for getting your equipment back in top shape. Designed to measure delivery pressure from 0 to 100 PSIG, this gauge is perfect for the low-pressure side of your regulator, giving you the feedback you need to set the perfect flow rate for MIG, TIG, or Oxy-Fuel applications.

Built to withstand the rigors of a busy welding shop, the GA143-03 features a tough steel case and a shatterproof polycarbonate lens. We all know that regulators can take a beating—whether they are dragged across the floor on a cylinder cart or bumped by heavy workpieces. The shatterproof crystal on this gauge ensures that a simple accident doesn't turn into a safety hazard or a replacement cost. The lens also features a protective lip design that adds an extra layer of defense against scratches and impacts, keeping your view of the pressure readings clear over the life of the tool.

Installation is straightforward and hassle-free. The gauge comes with a standard 1/4-inch male NPT brass thread, which is the industry standard for almost all regulator bodies, including those from Smith, Miller, Victor, and Harris. Simply apply a suitable thread sealant (compatible with the gas service) and screw it into the delivery port of your regulator. The brass inlet ensures a tight, leak-free seal that resists corrosion. With its high-contrast dial and watch-type precision movement, you can trust this gauge to provide steady, accurate readings, helping you maintain the precise parameters required for certified welds and high-quality fabrication work.
