Series GGS • True Blue Gauge Guards

(Diaphragm Seals/Instrument Isolators)
Please note that Series GGM has been replaced by Series GGS. Series GGS provides the same pressure ratings and performance as Series GGM, but has a larger volume upper housing featuring a non-breakable, solid hex stainless steel (non-wetted) gauge fitting.

Advantages:

NEW Design uses stainless steel hex insert (NON-WETTED) to prevent overtightening.
Low cost protection of gauges and other pressure instruments.
Available in a variety of thermoplastics for specific chemical compatibility and temperature ranges.
Increase product reliability and reduce system downtime caused by failure of instruments not isolated by seals.
Compact size makes these isolators ideal for limited-space installations.
±3% accuracy. Will handle most applications.
Use with gauges, transducers, and pressure switches.
Simple to fill and install.
For use with highly aggressive or ultra-pure liquids.
Diaphragm safety - If the gauge or instrument fractures while the system is pressurized, the diaphragm will automatically seal against leakage to the atmosphere.
Standard PTFE diaphragm (except for vacuum and 0-15 PSI; 0-1 bar) for maximum corrosion resistance.
Eliminates need for costly exotic metal gauges for corrosive processes.
Available with or without gauge (dual in PSI and bar).
Optional transparent shield for external corrosion protection.

Connections & Dimensional Data:

Gauge Port:  1/4 NPT standard

             1/2 NPT or BSP available (specify)

System Port: 1/2 NPT or BSP

Standard Gauge: 2 1/2" Stainless Steel; Shielded models use 2" gauge.

Note as illustrations show, revised design uses self-tapping fasteners to hold housing together.

IF 1/2" GAUGE CONNECTION REQUIRED ADD "X" AFTER SEAL MATERIAL example: GGTSX1-PV
FKM is Vinylidene Flouride - Hexafluoropropylene (Fluorocarbon). Viton®, for example, is a specific brand of FKM rubber.
