Ashcroft 83224 Pressure Gauge 0-300 Psi 3.5in Dial Npt

Product Description

The ASHCROFT 83224 is an analog industrial pressure gauge designed for accurate pressure monitoring in demanding trade and industrial applications. It features a 3.5-inch dial with a 0 to 300 psi measurement range and delivers 1% of scale accuracy. The gauge uses a 316 stainless steel Bourdon tube and a 304/316 stainless steel case, making it resistant to corrosion and suitable for harsh environments. A polycarbonate lens protects the dial face. The lower-mount, 1/4-inch NPT connection allows direct inline installation. Licensed HVAC, plumbing, and mechanical contractors are the primary installers of this type of gauge.

This gauge is suited for residential and commercial plumbing, HVAC, and general industrial piping systems where consistent pressure monitoring is required. The lower-mount configuration positions the dial face upward for easy reading when the gauge is installed on a vertical pipe or manifold. The dry (non-liquid-filled) design keeps maintenance simple and makes the gauge appropriate for applications where fluid contamination of the gauge internals is not a concern.

Compatibility

Designed as an OEM-style replacement or new-installation pressure gauge for residential and commercial plumbing, HVAC, and general industrial piping systems requiring a 1/4-inch NPT lower-mount gauge with a 3.5-inch dial and 0 to 300 psi range.

Installation Notes

Installation is typically performed by a licensed plumber or HVAC technician. Isolate and depressurize the system completely before removing an existing gauge or threading in a new one. Apply thread sealant or PTFE tape to the NPT threads in accordance with IPC or local mechanical code requirements. Do not exceed the rated maximum pressure of 300 psi during system testing or operation.
