Frequently Asked Questions

What is the ASHCROFT Process Pressure Gauge used for?

The ASHCROFT Process Pressure Gauge is used for measuring pressure in industrial systems where vibration is present. Its liquid-filled design dampens pointer flutter, making it suitable for pumps, compressors, and hydraulic equipment. The brass/bronze wetted parts handle compatible fluids, and the epoxy-coated aluminum case resists corrosion.

What are the specifications of the ASHCROFT Process Pressure Gauge?

This ASHCROFT gauge has a 4 1/2 in white dial, 0 psi to 400 psi range, ±0.5% accuracy, and a 1/2 in NPT male bottom connection. It features a black pointer, brass/bronze wetted parts, an epoxy-coated aluminum case, and is liquid-filled for vibration resistance. The manufacturer part number is 451379ASL04L400#.
