Ashcroft 93694XLL Pressure Gauge 4.5 in Dial 0-30 Psi Rear Flange

Product Description

The ASHCROFT 93694XLL is an analog pressure gauge designed for accurate pressure measurement in industrial, mechanical, and HVAC applications. Featuring a 4.5-inch dial face, this gauge delivers a 0 to 30 psi range with 0.5% of scale accuracy, making it suitable for low-pressure system monitoring where reliable readings matter. The aluminum case keeps weight down at 2.5 pounds while the bronze wetted parts provide corrosion resistance in water and compatible fluid services. The rear flange mount configuration simplifies panel or bulkhead installation. Licensed service technicians and pipefitters are the typical installers for this type of instrument.

This gauge is suited for residential and light commercial plumbing, hydronic heating systems, compressed air monitoring, and other low-pressure piping applications. The dry, no-fill design eliminates concerns about liquid-fill compatibility or leakage in environments where glycerin or silicone fill would be problematic. The 1/4-inch threaded connection and rear flange mount make it a straightforward drop-in for panel-mount installations where front-of-panel dial visibility is required.

Key Features

• 4.5-inch analog dial for clear, at-a-distance pressure readings
• 0 to 30 psi range with 0.5% of scale accuracy
• Bronze wetted parts for corrosion resistance in water and compatible media
• Aluminum case construction reduces overall instrument weight
• Rear flange mount design for panel or bulkhead installation
• Dry, no-fill construction eliminates liquid-fill maintenance concerns

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for low-pressure plumbing, HVAC, and compressed air systems requiring a rear flange mount, 1/4-inch threaded connection, and 4.5-inch dial format.

Installation Notes

Installation is typically performed by a licensed plumber, pipefitter, or HVAC technician. Isolate and depressurize the system fully before removing an existing gauge or installing this unit. Apply thread sealant appropriate to the service media on the 1/4-inch male thread before installation. Follow applicable IPC or IFGC code requirements for pressure instrument installation in the relevant system.
