Ashcroft 96249 Pressure Gauge 4.5 in 0-100 Psi Rear Flange

Product Description

The ASHCROFT 96249 is an analog pressure gauge designed for accurate pressure measurement in industrial, HVAC, plumbing, and mechanical systems. It features a 4.5-inch dial for clear, at-a-glance readings across a 0 to 100 psi range, with a rated accuracy of 0.5 percent of scale. The thermoplastic case resists corrosion and keeps weight low, making it suitable for a wide range of service environments. Connection is via a 1/4-inch rear thread, and the rear flange mount provides a clean panel or wall installation. This gauge is installed by licensed HVAC technicians, plumbers, and mechanical contractors wherever reliable pressure indication is required.

This gauge is suited for residential and light commercial applications where a mid-size, easy-to-read pressure indicator is needed. Typical install scenarios include boiler systems, compressed air lines, water supply systems, hydronic heating loops, and general mechanical equipment rooms. The non-liquid-filled design keeps the installation straightforward and eliminates concerns about filler fluid compatibility with the surrounding environment. The rear flange mount allows the gauge to be recessed into a panel or mounted flush against a surface for a clean, professional appearance.

Installation Notes

Installation is typically performed by a licensed plumber, HVAC technician, or mechanical contractor. Shut off and depressurize the system fully before removing an existing gauge or making any new connection. Apply appropriate thread sealant to the 1/4-inch male thread per local plumbing or mechanical code requirements. Do not over-torque the gauge fitting, as thermoplastic components can crack under excessive force.
