OVERVIEW

Technical Overview: 2.50" 0-100 PSI Pressure Gauge

The ESB999435 is a standard industrial pressure gauge designed for accurate monitoring of pneumatic and gas systems. It features a 2.50-inch (63.5mm) dial face, providing a clear and legible display for operators. The scale is calibrated from 0 to 100 PSI, making it suitable for low-to-medium pressure applications, such as delivery pressure readings on gas regulators or air line monitoring.

Constructed with a plastic (PLA) case, this gauge offers resistance to environmental factors while maintaining a lightweight profile. The internal mechanism is designed to provide consistent repeatability. The unit utilizes a Lower Back Mount (LBM) configuration, which is the standard orientation for panel mounting or direct installation into regulators where the dial must face the operator. The "BLU" designation indicates a blue housing or face accent, often used to color-code systems or denote specific gas lines in complex setups.

This gauge is an essential component for MRO (Maintenance, Repair, and Operations) inventories, serving as a direct replacement for damaged gauges on compressors, filter-regulator-lubricator (FRL) units, and welding gas delivery systems. Its NPT connection (standard for this size) ensures compatibility with a wide range of industrial fittings.

FAQ

This gauge measures pressure from 0 to 100 PSI.

The dial face has a diameter of 2.50 inches.

It features a Lower Back Mount (LBM), meaning the connection is on the back of the case, near the bottom center.

The case is made of plastic (PLA), offering corrosion resistance and a lightweight design.

Yes, if your regulator requires a 0-100 PSI gauge with a back mount connection (typically for reading the delivery pressure/flow), this is a suitable replacement.

BLU likely refers to the color of the gauge case or dial accents, which helps in identifying the gauge or matching it to specific equipment branding.

While many gauges are general purpose, gauges used for oxygen must be specifically cleaned for oxygen service to prevent combustion. Unless explicitly marked 'Use No Oil' or 'Oxygen Clean', assume it is for inert gas or air only.

Use a wrench on the brass connection stem (not the plastic case) to tighten the gauge into the port. Use teflon tape or thread sealant if appropriate for the gas service.
