Ashcroft 96259 Pressure Gauge 4.5 in 0-200 Psi Rear Flange

Product Description

The ASHCROFT 96259 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 200 psi and delivers 0.5% of scale accuracy. The thermoplastic case resists corrosion and impact, making it suitable for installations where moisture or chemical exposure is a concern. Connection is made via a 1/2-inch MNPT rear fitting with a flange mount configuration, providing a clean panel or wall installation. Licensed HVAC technicians, plumbers, and industrial maintenance professionals are the primary installers of this gauge.

The 96259 is suited for process piping, industrial fluid systems, and commercial mechanical installations where reliable pressure monitoring is required. The rear flange mount style integrates directly into panel cutouts or surface-mounted enclosures. The no-fill liquid configuration keeps the internals dry, which is appropriate for general-purpose gas and liquid pressure monitoring where vibration dampening is not a primary concern. Its glass lens and analog dial provide clear, direct reading under normal lighting conditions.

Compatibility

Designed as an OEM-style process gauge for industrial and commercial fluid systems requiring a 4.5-inch rear-flange-mount pressure indicator with a 1/2-inch MNPT connection and a 0 to 200 psi range.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial mechanic in accordance with applicable local codes. Depressurize and isolate the system completely before connecting or removing any pressure gauge. Apply thread sealant to the MNPT fitting per the sealant manufacturer instructions and avoid over-torquing the thermoplastic case. Verify the process fluid compatibility with the case and wetted materials before placing the gauge in service.
