OVERVIEW

Technical Overview of the Smith GA140-03 Pressure Gauge

The Smith Equipment GA140-03 is a precision-engineered replacement pressure gauge designed for the delivery (working pressure) side of industrial gas regulators. Engineered to meet the rigorous demands of welding, cutting, and HVAC applications, this instrument features a dual-scale dial reading from 0 to 200 PSIG and 0 to 14 BAR. The gauge is constructed with a robust steel case, providing necessary protection for the internal mechanism against external impacts common in shop environments. The inlet nipple is machined from brass, ensuring a secure, corrosion-resistant seal when mated with standard regulator bodies.

Accuracy and safety are paramount in gas regulation equipment. The GA140-03 utilizes a watch-type precision movement, which offers smooth needle operation and accurate pressure indication, critical for maintaining stable flow rates in oxy-fuel or shielding gas processes. The face is a high-visibility cupped steel design, ensuring legibility even in variable lighting conditions. For safety, the gauge is U.L. Listed and features a one-piece polycarbonate crystal. This crystal is shatterproof, eliminating the hazard of flying glass in the event of a pressure spike or physical damage. Additionally, the crystal design includes a protective lip that guards the face of the gauge from direct contact damage.

Installation is standardized via a 1/4-inch Male National Pipe Thread (MNPT) connection, typically oriented for bottom mounting. This thread size is the industry standard for the majority of gas pressure regulators, making the GA140-03 a versatile stock item for maintenance departments. It is compatible with all major brands of gas pressure regulators that utilize 1/4" FNPT gauge inlet threads. The unit is designed for service pressures up to 200 PSIG, making it suitable for oxygen, inert gases, and other non-corrosive gas applications where delivery pressure monitoring is required.

FAQ

This gauge features a 1/4" NPT (National Pipe Thread) Male connection.

This is a low-pressure gauge (0-200 PSI) typically used for the delivery/hose pressure side of the regulator.

Yes, provided the regulator uses a standard 1/4" NPT female port for the gauge, which is common across most major brands.

No, the lens is made of one-piece shatterproof polycarbonate for increased safety and durability.

The scale reads up to 200 PSIG (14 BAR).

While the pressure range covers Acetylene delivery pressures, Acetylene gauges often have a red line above 15 PSI. This gauge is a general 0-200 PSI gauge, often used for Oxygen or Inert gases, but physically fits any 1/4" NPT port.

No, thread sealant or tape is not included and should be applied separately during installation.

Smith gauges intended for oxygen service are typically cleaned for oxygen service, but always check the packaging for specific 'Use No Oil' warnings before installing on oxygen systems.
