Gauge Isolators – SG Series
Chemline SG Series Gauge Isolators allow inexpensive pressure gauges, or any other pressure instrument to be used in corrosive services. The upper chamber (gauge side) is filled with a stable fluid such as glycol or glycerine. A diaphragm separates it from the lower chamber which receives the media under pressure.
The 1/2″ gauge connection allows use of the popular 4″ and 4-1/2″ diameter gauges. Pressure switches or transmitters may also be installed. Customers can easily fill isolators and install their own gauges.

Features & Benefits
- Easy to Mount Gauges
It is easy to fill an isolator and field mount a gauge. No special equipment is required.
Will accept popular 4” and 4-1/2” diameter gauges. - Provision for Fill Port
Housing may be drilled and tapped by Chemline or customer for a threaded fill port. This is used for filling isolator using a vacuum filling station. - High Chemical Resistance
Choice of body materials for a wide range of applications.
PTFE bonded EPDM dished diaphragm for high chemical resistance and sensitivity. - Heavy Duty Design for Safety
PPG top chamber.
Heavy wall connection ports. - Optional Gauges
Isolators are available alone or with gauge mounted and prefilled with glycol.
