Ashcroft 96225 Pressure Gauge 4.5 in Dial 0-100 Psi Rear Flange

Product Description

The ASHCROFT 96225 is an analog pressure gauge designed for monitoring system pressure in a wide range of industrial and mechanical applications. It features a 4.5-inch dial for clear, at-a-glance readings and a thermoplastic case that resists corrosion and impact in field environments. The gauge covers a pressure range of 0 to 100 psi with an accuracy of 0.5 percent of scale, making it suitable for applications where reliable pressure indication is required. It is not liquid-filled, which keeps weight low and simplifies installation. Rear flange mounting allows the gauge to be panel-mounted or surface-mounted directly against a bulkhead or enclosure wall.

This gauge is appropriate for residential and light commercial mechanical systems including HVAC equipment, compressed air lines, water systems, and process piping where a durable, readable pressure indicator is needed. The rear flange mount configuration is commonly used when the gauge body must sit flush against a panel or mounting surface. The 0.5-inch threaded connection provides a standard interface to most system ports and fittings. Licensed plumbers, HVAC technicians, and mechanical contractors typically specify this style of gauge for permanent panel installations and test stations.

Key Features

• 4.5-inch analog dial for clear pressure readings at distance
• 0 to 100 psi pressure range with 0.5 percent of scale accuracy
• Rear flange mount configuration for panel and surface installations
• Thermoplastic case construction for corrosion resistance and reduced weight
• Non-liquid-filled design simplifies installation and reduces overall weight
• 0.5-inch threaded connection for standard fitting compatibility

Compatibility

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

Installation Notes

Installation should be performed by a qualified HVAC technician, plumber, or mechanical contractor in accordance with applicable local codes and the system manufacturer guidelines. De-pressurize and isolate the system completely before removing any existing gauge or fitting the new gauge. Apply appropriate thread sealant to the male threads per the system requirements and hand-tighten before using a wrench to avoid overtorquing the thermoplastic-adjacent fittings. Verify the gauge reads zero before re-pressurizing the system.
