OVERVIEW

Smith Equipment GA137-03 2" Replacement Pressure Gauge (0-150 PSI)

The Smith Equipment GA137-03 is a high-quality replacement pressure gauge designed for industrial gas regulators. Engineered to meet Smith's rigid quality standards, this 2-inch (51mm) gauge provides accurate readings for delivery pressure applications ranging from 0 to 150 PSI (0-10 Bar). It is an essential component for maintaining the safety and efficiency of oxy-fuel and inert gas welding setups.

Constructed for the harsh industrial environment, the gauge features a robust steel case with a black finish and a high-visibility cupped steel face. The internal mechanism utilizes a precision watch-type movement, ensuring optimum accuracy and repeatability in pressure readings. This level of precision is critical for welders and fabricators who rely on consistent gas flow for quality welds.

Safety and durability are paramount in the design of the GA137-03. The face is protected by a one-piece polycarbonate crystal that is shatter-resistant, significantly reducing the risk of breakage compared to glass lenses. The crystal also features a protective lip to prevent damage to the gauge face during handling or accidental impact. The unit is U.L. Listed, confirming its adherence to strict safety standards required for compressed gas equipment.

Installation is straightforward with the standard 1/4" NPT male bottom connection, making it compatible with all major brands of gas pressure regulators that utilize 1/4" FNPT gauge inlet threads. Whether replacing a damaged gauge on a Smith regulator or upgrading a compatible unit, the GA137-03 offers reliable performance and longevity.

FAQ

This gauge has a 1/4" NPT Male thread, which is the standard size for most industrial gas regulators.

This is a 0-150 PSI gauge, which is typically used for the delivery (hose) pressure side. Tank pressure gauges usually read up to 4000 PSI.

Yes, as long as the regulator has a standard 1/4" NPT female port for the gauge, this Smith gauge will fit.

The lens is made of one-piece polycarbonate, which is shatter-resistant and much more durable than glass.

The gauge reads from 0 to 150 PSI and also displays 0 to 10 Bar.

While the pressure range covers Acetylene working pressures, Acetylene delivery gauges typically have a red line at 15 PSI for safety awareness. This 0-150 PSI gauge is better suited for Oxygen or Inert gases.

Yes, gauges intended for welding service, especially oxygen service, are manufactured to be free of oil and grease to prevent combustion hazards.

No, it does not typically include thread tape. When installing, use a PTFE tape compatible with oxygen service if required, but be careful not to obstruct the inlet.
