Pressure Gauge Isolators by Sigmamotor

Sigmamotor pressure gauge isolators allow standard pressure gauges to be used in corrosive services. The upper section (gauge side) is filled with glycerine. A diaphragm separates the glycerin from the lower section which connects to the pressure source. A 1/2” FNPT port is provided for connection to the pressure source. Materials are PVC body with VitonTM diaphragm.
