Ashcroft 94224 Industrial Pressure Gauge 0-3000 Psi

Product Description

The ASHCROFT 94224 is a liquid-filled industrial pressure gauge rated from 0 to 3000 psi, designed for demanding trade and industrial applications where accurate, reliable pressure monitoring is required. The gauge features a 3.5-inch analog dial with 1% of scale accuracy, housed in a 304/316 stainless steel case with a polycarbonate lens. The Bourdon tube is 316 stainless steel for corrosion resistance. The lower-mount 1/4-inch NPT connection makes it straightforward to install inline on pressurized systems. Liquid fill dampens vibration and pulsation to protect the movement and maintain readability under dynamic conditions.

This gauge is suited for use in HVAC, plumbing, hydraulic, and industrial process systems where pressures up to 3000 psi must be monitored. The stainless steel construction makes it appropriate for environments with moisture, mild chemicals, or outdoor exposure. The lower-mount configuration is common in panel-mount and pipe-mount installations where the gauge sits directly above the process connection. Licensed plumbers, HVAC technicians, and industrial maintenance personnel are the typical installers for this type of gauge.

Compatibility

Designed as an OEM-style and aftermarket replacement industrial pressure gauge for systems using a 1/4-inch NPT lower-mount connection and requiring a 3.5-inch dial with a 0 to 3000 psi range.

Installation Notes

Installation should be performed by a qualified technician or licensed plumber familiar with pressurized system work. Shut down and fully depressurize the system before removing any existing gauge or making connections. Apply thread sealant appropriate for the system media and pressure rating to the NPT threads. Do not over-torque the connection; refer to the system manufacturer's guidelines for fitting torque. Verify the gauge range and process compatibility before placing into service.
