Ashcroft 93760XLL Pressure Gauge 4.5 in Dial 0-30 Psi

Product Description

The ASHCROFT 93760XLL is an analog pressure gauge designed for accurate pressure measurement in industrial and mechanical systems. It features a 4.5-inch dial for easy readability and delivers 0.5% of scale accuracy across a range of 0 to 30 psi. The aluminum case keeps weight low while stainless steel wetted parts provide corrosion resistance in demanding fluid and gas service environments. This gauge uses a rear flange mount configuration and is not liquid-filled, making it suited for clean, non-pulsating service. Licensed plumbers, pipefitters, and HVAC technicians commonly install this type of gauge during system commissioning, testing, and ongoing pressure monitoring.

This gauge is appropriate for residential and light commercial mechanical systems where low-range pressure readings are required. Typical applications include hydronic heating systems, compressed air lines, water supply systems, and HVAC refrigerant-adjacent monitoring where direct refrigerant contact is not involved. The dry, non-liquid-filled construction is best suited for environments free of heavy vibration or pressure spikes. The rear flange mount allows for panel or wall-mount installation, keeping the dial face flush and accessible for routine readings.

Key Features

• 4.5-inch analog dial for clear, at-a-distance pressure readings
• 0 to 30 psi pressure range suitable for low-pressure system monitoring
• 0.5% of scale accuracy for reliable measurement in critical applications
• Stainless steel wetted parts resist corrosion in water and mild fluid service
• Aluminum case reduces overall gauge weight
• Rear flange mount design supports panel and wall-mount installations
• Non-liquid-filled construction for use in low-vibration, stable-pressure environments

Compatibility

Designed as an OEM-style replacement or new-installation gauge for low-pressure mechanical systems requiring a rear-flange-mount analog pressure gauge with a 4.5-inch dial and 0.5-inch thread connection.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified HVAC technician in accordance with applicable local codes and ASME B40.100 guidelines for pressure gauge installation. Isolate and depressurize the system fully before removing any existing gauge or making new connections. Apply appropriate thread sealant to the male threads and avoid over-tightening, which can damage the gauge socket. Do not install this non-liquid-filled gauge on systems with severe vibration or pressure pulsation without adding a snubber or isolator.
