Bottom Mount Pressure Gauge 4" - 3000 PSI

Liquid filled gauges will help to increase the accuracy and authenticity of your measuring system providing a series of benefits such as:

• Absorbs and dampens vibrations, which allows for accurate readings even during times of intense resonance.


• Wear and tear on the gauge is greatly reduced because the liquid provides lubrication for all of the moving elements in the gauge.


• Performs in corrosive environments and discourages icing and rusting within the measurement system.
