Ashcroft 96255 Pressure Gauge 4.5 in Dial 0-1000 Psi Rear Flange

Product Description

The ASHCROFT 96255 is an analog pressure gauge built for trade professionals who need reliable, accurate pressure readings in demanding field and mechanical room environments. The gauge features a 4.5-inch dial for clear at-a-distance readability, a pressure range of 0 to 1000 psi, and an accuracy rating of 0.5 percent of scale. The thermoplastic case offers corrosion resistance without the added weight of stainless or brass housings. A 1/4-inch rear-threaded connection and rear flange mount make this gauge well-suited for panel installations where a clean, flush-mount appearance is required. It is a no-fill, dry gauge design with no liquid fill medium.

The ASHCROFT 96255 is commonly used in HVAC, plumbing, and industrial service applications where process pressures up to 1000 psi must be monitored at a fixed panel or equipment enclosure. The rear flange mount allows the gauge to be secured to a panel face while the rear connection routes directly into the pipe or port behind the panel. This configuration is standard in boiler rooms, pump stations, compressor skids, and air distribution systems where a clean front-panel gauge display is required by installation design or code.

Key Features

• 4.5-inch analog dial for clear, easy-to-read pressure indication at a distance
• Pressure range of 0 to 1000 psi suitable for high-pressure HVAC, plumbing, and mechanical applications
• 0.5 percent of scale accuracy for reliable process monitoring
• Rear flange mount design supports flush panel installation
• 1/4-inch rear thread connection for direct inline or panel mounting
• Thermoplastic case provides corrosion resistance in wet or chemically active environments
• Dry, no-fill gauge eliminates concerns about liquid filler compatibility or leakage

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial mechanical systems requiring a 4.5-inch rear-flange-mount analog gauge with a 1/4-inch rear threaded connection and a 0 to 1000 psi range.

Installation Notes

Installation is typically performed by licensed plumbers, pipefitters, or HVAC technicians in accordance with applicable mechanical and plumbing codes. Always isolate and depressurize the system before removing or installing any pressure gauge. Use appropriate thread sealant on the 1/4-inch NPT connection and avoid over-tightening the threaded fitting, which can stress the gauge socket. Confirm the process pressure range does not exceed the gauge maximum of 1000 psi during normal or transient operating conditions.
