Gauge Guard Isolator

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