Ashcroft 93030XLL Pressure Gauge 4.5 in Dial 800 Psi Rear Flange

Product Description

The ASHCROFT 93030XLL is an analog pressure gauge designed for accurate pressure monitoring in industrial, commercial, and mechanical systems. It features a 4.5-inch dial for clear, at-a-distance readability and a rear flange mount for panel or wall installation. The gauge covers a range of 0 to 800 psi with an accuracy of 0.5 percent of scale, making it suitable for applications that require reliable, repeatable readings. The thermoplastic case offers resistance to corrosion in light-duty environments. This gauge is installed by licensed plumbers, HVAC technicians, and pipefitters in a wide range of pressure monitoring applications.

This gauge is well suited for residential and commercial mechanical rooms, pump stations, compressor systems, and process piping where panel-mounted instrumentation is required. The rear flange mount configuration allows flush or surface panel mounting, keeping the gauge face accessible for routine reading. The 0.5-inch threaded connection accommodates standard pipe fittings. With a dry, no-fill design, it is appropriate for clean gas and liquid service where liquid-filled dampening is not required.

Key Features

• 4.5-inch analog dial for clear pressure readings at a distance
• 0 to 800 psi pressure range suitable for medium to high-pressure systems
• 0.5 percent of scale accuracy for reliable, repeatable monitoring
• Rear flange mount design supports panel and surface installation
• Thermoplastic case provides corrosion resistance in light-duty service
• Dry, no-fill construction for clean gas and liquid applications

Compatibility

Designed as an OEM-style replacement or direct-install pressure gauge for panel-mounted instrumentation in commercial and industrial mechanical systems requiring a rear flange mount configuration with a 0.5-inch threaded connection.

Installation Notes

Installation is typically performed by a licensed plumber or pipefitter. Shut off and fully depressurize the system before removing or installing any pressure gauge. Use appropriate thread sealant on the pipe connection and verify the connection is wrench-tight without over-torquing the thermoplastic body. Verify the gauge pressure range is appropriate for the system operating pressure before returning the system to service.
