Ashcroft 96252 Pressure Gauge 0-300 Psi 4.5 in Rear Flange

Product Description

The ASHCROFT 96252 is a process industrial pressure gauge designed for demanding commercial and industrial applications. It features a 4.5-inch analog dial with a measurement range of 0 to 300 psi and delivers 0.5% of scale accuracy. The case is constructed from thermoplastic for corrosion resistance in harsh environments. The gauge uses a 0.25-inch MNPT rear connection with a flange mount configuration, making it suitable for panel or wall installations. It is a non-liquid-filled gauge with a glass lens. Licensed tradespeople and instrumentation technicians typically specify this gauge for process lines, HVAC systems, and utility monitoring where a clear, accurate pressure reading is required.

This gauge is suited for process and industrial installations in both commercial and light industrial settings. The rear flange mount design allows it to be flush-mounted into panels or bulkheads, keeping the dial face accessible for routine readings. It carries CRN certification and meets IP66 and NEMA 4X ratings, making it appropriate for outdoor installations or environments exposed to water ingress and washdowns. It is part of the Ashcroft 1279 series.

Key Features

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for process piping, HVAC systems, and industrial monitoring applications requiring a 0.25-inch MNPT rear-entry connection with flange mount. Compatible with systems rated up to 300 psi. CRN certified for use in applicable Canadian jurisdictions.

Installation Notes

Installation should be performed by a qualified instrumentation technician or licensed pipefitter following applicable local codes. Depressurize and isolate the process line completely before installing or removing the gauge. Apply appropriate thread sealant to the MNPT connection and hand-tighten before final torque with a wrench on the gauge fitting, not the case. Verify the system pressure does not exceed the 300 psi maximum range of the gauge before returning the line to service.
