Rubber Fab Gauge Guard Isolator gaskets

Protect Expensive Equipment with the Gauge Guard Isolators

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.
