Ashcroft 80738XLL Pressure Gauge 4.5 in 0-15 Psi Rear Flange

Product Description

The ASHCROFT 80738XLL is an analog pressure gauge designed for accurate pressure monitoring in fluid and gas systems. It features a 4.5-inch dial for easy readout at a distance and a rear flange mount configuration for panel or wall installations. The wetted parts are bronze, making the gauge suitable for use with a broad range of media compatible with that material. The aluminum case keeps weight low while providing structural protection. Accuracy is rated at 0.5 percent of scale across a pressure range of 0 to 15 psi. This gauge is installed by HVAC technicians, plumbers, and mechanical contractors in both residential and light commercial settings.

This gauge is suited for low-pressure applications including water supply lines, boiler systems, compressed air circuits, and fluid handling equipment where a clear panel-mount indicator is required. The rear flange mount allows flush or panel-mounting in control enclosures and equipment housings. It ships as a dry, no-fill unit, which simplifies installation in environments where liquid-filled gauges are not required or practical.

Key Features

• 4.5-inch analog dial for clear, distance-readable pressure indication
• 0 to 15 psi range suitable for low-pressure fluid and gas monitoring
• 0.5 percent of scale accuracy for reliable readings
• Rear flange mount for panel or wall installation
• Bronze wetted parts for broad media compatibility
• Aluminum case construction reduces overall instrument weight
• Dry, no-fill design simplifies installation and maintenance

Compatibility

Designed as an OEM-style or replacement pressure gauge for low-pressure fluid and gas monitoring applications in residential and light commercial mechanical systems.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor. Shut off and depressurize the system completely before removing or installing any pressure gauge. Use appropriate thread sealant on the 0.5-inch threaded connection per applicable installation codes. Do not exceed the rated pressure range of the gauge, as overrange conditions can damage the bourdon tube and return inaccurate readings.
