Pressure Gauge Chemical Seal / Isolator

Provides isolation from hazardous or corrosive fluids
  • CNC precision machined parts
  • Cost effective and reliable
  • Two pressure ranges: 0-60PSI and 0-160PSI
  • Pre-filled with glycerin between gauge and diaphragm

Sigmamotor pressure gauge isolators allow inexpensive 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 with Viton™ diaphragm.
