Ashcroft 96253 Pressure Gauge 4.5 in Dial 0-400 Psi Rear Flange

Product Description

The ASHCROFT 96253 is an analog pressure gauge built for trade and industrial applications where reliable pressure monitoring is required. Featuring a 4.5-inch dial for easy reading at a distance, this gauge covers a pressure range of 0 to 400 psi with an accuracy of 0.5 percent of scale. The rear flange mount design allows direct panel or surface installation with a clean front face. The thermoplastic case resists corrosion in moderate environments, making it a practical choice for plumbing, HVAC, and general mechanical systems. It is a dry-fill (no liquid filler) gauge, suited for applications with low vibration. Installation is performed by licensed plumbers, HVAC technicians, or qualified mechanical contractors.

This gauge is well suited for residential and light commercial applications where process pressure readings are needed at a panel, manifold, or inline connection point. The 1/4-inch thread connection and rear flange mount make it a standard fit for typical pressure monitoring stations in water systems, compressed air lines, and HVAC hydronic circuits. The 4.5-inch dial size improves legibility in control panel installations and equipment rooms where gauges are read from a distance.

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and light commercial plumbing, HVAC hydronic, and compressed air systems requiring a 4.5-inch rear-flange-mount gauge with a 1/4-inch threaded connection.

Installation Notes

Installation should be performed by a licensed plumber, HVAC technician, or qualified mechanical contractor in accordance with applicable local codes and IPC or IFGC requirements. Depressurize and isolate the system completely before removing an existing gauge or making any threaded connections. Apply appropriate thread sealant to the 1/4-inch connection per the system fluid and code requirements. Do not overtighten the threaded connection, as thermoplastic components can be damaged by excessive torque.
