Ashcroft 80454XLL Pressure Gauge 4.5 in Dial Rear Flange

Product Description

The ASHCROFT 80454XLL is an analog pressure gauge designed for high-pressure measurement applications in industrial, HVAC, and mechanical systems. The gauge features a 4.5-inch dial face for easy readability at a distance, a stainless steel wetted parts construction for corrosion resistance, and an aluminum case for durability with reduced weight. It covers a pressure range of 0 to 10000 psi with an accuracy rating of 0.5 percent of scale, making it well suited for demanding process and utility monitoring where reliable pressure indication is required.

This gauge is configured for rear flange mounting, which allows it to be panel-mounted or surface-mounted flush to a bulkhead or bracket. The dry, non-liquid-filled design simplifies installation and maintenance in environments where vibration is not a primary concern. It connects via a 0.5-inch threaded fitting. Typical applications include compressed air systems, hydraulic lines, industrial process piping, and mechanical room instrumentation monitored by licensed HVAC technicians, plumbers, and pipefitters.

Key Features

• 4.5-inch analog dial face for clear, at-a-glance pressure readings
• 0 to 10000 psi pressure range for high-pressure system monitoring
• 0.5 percent of scale accuracy for reliable process measurement
• Stainless steel wetted parts resist corrosion from process media
• Aluminum case provides lightweight durability
• Rear flange mount configuration for panel or bulkhead installation
• Dry, non-liquid-filled design for straightforward servicing

Compatibility

Designed as a direct-mount analog pressure gauge suitable for industrial and mechanical systems using 0.5-inch threaded connections and requiring rear flange panel mounting in high-pressure service up to 10000 psi.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians. Isolate and depressurize the system fully before removing any existing gauge or installing this unit. Apply appropriate thread sealant to the 0.5-inch threaded connection per the fitting manufacturer and applicable IPC or IFGC guidelines. Do not over-tighten the threaded connection; use the gauge case flange and a proper wrench on the hex fitting, not the dial body, to avoid damage.
