Rubber Fab’s Gauge Guard Isolator gaskets protect expensive diaphragms and instruments from damage without affecting instrument performance.

By combining a quality Rubber Fab sanitary gasket with a membrane, the Gauge Guard Isolator gasket isolates hot or caustic saline solution from instrumentation, a necessary and cost effective step in assuring long life and accurate results from your instruments and gauges.

As some manufacturers will suggest the use of a gauge guard gasket, others note that the failure to use a gauge guard gasket can void most instrument and gauge warranties.

  • 1/2" and 3/4" Elastomers have .015 membrane thickness
  • 1", 1-1/2" & 2" Elastomers have .012" membrane thickness
  • PTFE & Tuf-Steel® have .002" membrane thickness
  • Gasket membrane 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
