Ashcroft 93022XLL Pressure Gauge 4.5 in Dial 0-30 Psi

Product Description

The ASHCROFT 93022XLL is an analog pressure gauge built for accurate, reliable pressure monitoring in demanding trade environments. It features a 4.5-inch dial for clear readability at a distance, a 0 to 30 psi pressure range, and a thermoplastic case that resists corrosion and impact. Accuracy is rated at 0.5 percent of scale, making it suitable for applications where precise readings are critical. The rear flange mount configuration allows the gauge to be panel-mounted flush against a surface, keeping the face fully visible. This gauge is dry (no liquid fill), which simplifies installation and reduces weight. HVAC technicians, plumbers, and mechanical contractors commonly specify this type of gauge for system monitoring and diagnostic work.

This gauge is well suited for residential and light commercial plumbing, HVAC, and mechanical systems where low-range pressure monitoring is required. The 4.5-inch dial size improves legibility in equipment rooms, boiler areas, and panel installations. The 1/4-inch threaded connection is a common size across a wide range of system fittings and manifolds, making it straightforward to integrate into most existing piping arrangements. Its thermoplastic case performs adequately in typical indoor mechanical environments. Licensed plumbers, HVAC technicians, and mechanical contractors are the primary installers.

Key Features

• 4.5-inch analog dial for clear, at-a-distance reading
• 0 to 30 psi pressure range suitable for low-pressure system monitoring
• 0.5 percent of scale accuracy for reliable measurement
• Rear flange mount design supports flush panel installation
• Thermoplastic case provides corrosion and impact resistance
• Dry, no-fill design reduces weight and simplifies service

Compatibility

Designed as an OEM-style replacement or new-installation gauge for low-pressure residential and commercial plumbing, HVAC, and mechanical systems using 1/4-inch threaded gauge ports.

Installation Notes

Installation should be performed by a licensed plumber or qualified mechanical technician. Isolate and depressurize the system fully before removing an existing gauge or making any threaded connection. Use appropriate thread sealant or PTFE tape on the 1/4-inch male threads and avoid over-tightening, which can crack a thermoplastic-case gauge. Verify the system pressure range does not exceed the gauge rating before returning the system to service.
