4'' DIAL0-30 PSI PISTON TYPE DIFFERENTIAL PRESSURE GAUGES

A Piston Type Differential Pressure Gauge measures the pressure difference between the high-pressure and low-pressure ports using a magnetic piston and compression spring. It is commonly used for filters, water treatment, hydraulic systems, air dryers and leak detection.Type Piston Type Differential Pressure Gauge
