Ashcroft 96228 Pressure Gauge 4.5 in 0-300 Psi Rear Flange

Product Description

The ASHCROFT 96228 is an analog process industrial pressure gauge built for demanding industrial and mechanical system applications. It features a 4.5-inch dial with a measurement range of 0 to 300 psi and delivers an accuracy of 0.5 percent of scale, making it suitable for applications where reliable pressure indication is critical. The thermoplastic case and glass lens provide durability in wet and dusty environments. Connection is made via a 1/2-inch MNPT rear-entry fitting, and the rear flange mount allows for panel or wall installation. HVAC technicians, plumbers, and industrial maintenance professionals install this gauge as part of pressure monitoring systems on process lines, mechanical equipment, and fluid systems.

This gauge is suited for residential and commercial mechanical systems where panel-mounted pressure indication is required. The rear flange mount configuration integrates cleanly into control panels or pipe assemblies. With no liquid fill and a thermoplastic case rated to IP66 and NEMA 4X, it performs in environments exposed to moisture, dust, and washdown conditions. The 0 to 300 psi range covers a broad spectrum of process and HVAC fluid system pressure monitoring needs. Installation is handled by licensed plumbers, pipefitters, or industrial maintenance technicians.

Key Features

• 4.5-inch analog dial with 0 to 300 psi measurement range
• 0.5 percent of scale accuracy for reliable process monitoring
• Thermoplastic case rated IP66 and NEMA 4X for moisture and dust resistance
• 1/2-inch MNPT rear-entry connection for straightforward pipe integration
• Rear flange mount design for panel or wall-mounted installations
• No liquid fill construction reduces maintenance requirements
• Glass lens for clear, durable dial visibility

Compatibility

Designed as an OEM-style or direct replacement process pressure gauge for industrial and mechanical fluid systems requiring a 4.5-inch rear-flange-mount analog gauge with a 1/2-inch MNPT connection and a 0 to 300 psi range. Certified to CRN standards.

Installation Notes

Installation should be performed by a licensed plumber, pipefitter, or qualified industrial maintenance technician. Depressurize and isolate the system fully before removing an existing gauge or installing this unit. Apply appropriate thread sealant to the MNPT connection per the applicable plumbing or process piping code. Do not over-tighten the fitting, as thermoplastic components require careful torque management during assembly.
