19134 - 2.5-Inch Replacement Pressure Gauge, 0-30 PSI, Lower Back Mount

Technical Overview

The ESAB 19134 Pressure Gauge is a precision instrumentation component designed specifically for low-pressure monitoring applications within industrial and welding environments. Engineered with a 2.50-inch diameter dial, this gauge offers superior readability compared to smaller standard variants, allowing operators to discern minor pressure fluctuations with ease. The scale is calibrated from 0 to 30 PSI (Pounds per Square Inch), a range specifically selected for applications requiring fine control over outlet pressures, such as the delivery side of shielding gas regulators, purge lines, or low-pressure pneumatic actuation systems.

The unit features a Lower Back Mount (LBM) configuration, which is the industry standard for panel-mounted equipment and many regulator bodies where the gauge must sit flush or perpendicular to the viewing angle. This orientation facilitates a streamlined setup, reducing the protrusion of the gauge and minimizing the risk of accidental impact damage in busy workshop environments. The internal mechanism is housed within a casing designated as 'PLA', indicating a durable plastic construction. This material choice offers distinct advantages in specific environments, providing natural resistance to corrosion and reducing the overall weight of the assembly without compromising the structural integrity required for low-pressure service.

Visually, the gauge utilizes a high-contrast white face with distinct, legible markings. This design consideration is critical in industrial settings where lighting may be suboptimal or where smoke and fume could obscure visibility. The clear lens protects the needle and face from dust, debris, and spatter, ensuring long-term legibility. As a replacement part, the ESAB 19134 is engineered to meet the original equipment manufacturer (OEM) specifications of ESAB and Victor gas equipment, ensuring seamless integration and performance consistency. It is suitable for use with inert gases typically used in welding, such as Argon, Helium, and CO2 mixtures, provided the pressure remains within the 30 PSI limit.

Maintenance and calibration of pressure instrumentation are vital for quality assurance in manufacturing. A compromised gauge can lead to incorrect flow rates, resulting in weld defects like porosity or oxidation. By replacing worn or damaged gauges with the ESAB 19134, facilities can restore the accuracy of their gas delivery systems. The gauge's robust design ensures a long service life, provided it is not subjected to pressures exceeding its maximum rating or physical abuse.
