Gauge Guard Isolator Gaskets


The Gauge Guard Isolator Gaskets protect valuable (stainless steel) pressure gauge diaphragms and other instruments without compromising performance. 

The high quality gasket with membrane isolates the instrumentation from hot or caustic saline solutions. This is a necessary and cost effective step in extending the life of instruments and meters, as well as ensuring lasting accurate results. Most manufacturers will therefore recommend the use of protection for instrumentation. 

Features & benefits

  • Gasket protects instrumentation from caustic saline solutions
  • Will not interfere with gauge operation or accuracy
  • Works with most industry standard instruments
  • Helps extend the life of gauges
