Rubber Fab – Gauge Guard Isolator Gaskets

Protects gauges and other expensive equipment


  • 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





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.

Kindly notice that those products are engineered and produced following client requests. Each product needs to be calibrated for special properties such as size or connection. In order to make it possible, our sales team will assist you to determine those criteria together. Only when this process is finished ROMYNOX will we be able to produce a quote and share a price.
