999505 - 2.5-Inch Low Pressure Gauge, 0-30 PSI, Lower Back Mount

Precision Low-Pressure Monitoring

The ESAB 999505 is a specialized pressure gauge designed for industrial and welding applications requiring accurate monitoring of low-pressure systems. With a maximum reading of 30 PSI, this gauge is specifically calibrated for sensitive delivery pressure readings, ensuring that operators can maintain precise control over gas flow. The 2.5-inch dial face provides an optimal balance between compactness and readability, allowing for quick visual checks without straining to see fine graduations.

Robust Construction and Design

Built to withstand the rigors of industrial environments, this gauge features a durable plastic case (PLA) that offers resistance to corrosion and impact. The "BLU" designation typically indicates a blue color-coding, which is often used in the industry to denote specific gas services or simply to differentiate low-pressure gauges from high-pressure cylinder gauges. The internal mechanism is engineered to provide consistent repeatability, ensuring that the needle movement is smooth and reflective of the actual system pressure.

Installation and Compatibility

This unit utilizes a Lower Back Mount (LBM) configuration, which is the standard orientation for many panel-mounted systems and gas regulators. This allows the gauge to sit flush or protrude correctly from the equipment face, keeping the dial upright and legible. Whether you are replacing a damaged gauge on an existing regulator or building a custom gas delivery manifold, the ESAB 999505 offers the fit and function required for professional setups. Its standard connection design ensures compatibility with a wide range of industrial gas equipment.

Safety and Maintenance

Replacing a faulty or broken gauge is critical for safety and process quality. A gauge that sticks or reads incorrectly can lead to improper gas mixtures, poor weld quality, or safety hazards. This replacement part allows maintenance teams to quickly restore equipment to full operational status. The clear lens and high-contrast markings facilitate immediate recognition of pressure anomalies, contributing to a safer work environment.
