Gauge Guards – also known as Diaphragm Seals or Instrument Isolators
Series GGS/GGSE

• Choice of Geon® PVC, Corzan® CPVC, Natural Polypropylene, Glass-Filled Polypropylene, Kynar® PVDF.
• Available with or without gauge (dual in PSI and bar). When ordered with gauge, you have choice of a premium 2 1/2" stainless steel case, or an economical 2" black steel case with brass connection. Both types are offered in pressure or vacuum.
• 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.
