OVERVIEW

Technical Overview: ESAB 2.50" Pressure Gauge (0-200 PSI)

The ESAB 999438 is a precision replacement pressure gauge designed for industrial gas regulation systems. Engineered with a 2.50-inch diameter dial, this gauge provides a clear and legible display of pressure readings ranging from 0 to 200 PSI. The scale is calibrated to ensure accuracy for delivery pressure monitoring, particularly in fuel gas applications where precise flow control is critical for flame stability and process consistency.

This specific model features a Lower Back Mount (LBM) connection, a standard configuration for many industrial gas regulators and panel-mounted systems. The connection allows the gauge to sit flush or protrude correctly from the regulator body, ensuring the face is oriented for the operator. The internal mechanism is housed within a durable Plastic (PLA) case. This material choice offers significant advantages in specific environments, providing resistance to atmospheric corrosion and reducing the overall weight of the assembly without compromising the protection of the internal bourdon tube and movement.

Safety is paramount in welding and cutting operations. This gauge utilizes the industry-standard Red color coding, visually identifying it for use with Fuel Gases (such as Acetylene, Propane, or Propylene) or other compatible services requiring this pressure range. The 0-200 PSI range is versatile, often used for high-pressure delivery settings or specific cylinder monitoring applications depending on the gas type. Technicians and maintenance personnel can rely on this component to restore the functionality of regulators, ensuring that downstream equipment receives the correct pressure for safe operation.

FAQ

This gauge measures pressure from 0 to 200 PSI.

In the welding industry, red typically indicates that the gauge is intended for Fuel Gas service (such as Acetylene, Propane, or Natural Gas).

The dial face is 2.50 inches in diameter.

It features a Lower Back Mount (LBM) connection, meaning the threaded stem comes out of the back of the gauge near the bottom.

This specific model (PLA) features a durable plastic case.

While the pressure range might be sufficient for some delivery applications, Oxygen gauges are typically Green. It is best practice to use the correct color code for safety to avoid confusion.

Most 2.5-inch gauges utilize a 1/4" NPT thread, though it is always recommended to measure your existing port to confirm.

Yes, it is designed for industrial environments, though the plastic case is lighter duty than brass or steel encased models.
