Gauge Chemical Seal / Isolator
Provides isolation from hazardous or corrosive fluids
precision machined parts
effective and reliable
pressure ranges: 0-60PSI and 0-160PSI
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.
