Gauge Guards

Gauge guards isolate and protect gauges and other instruments from the process media, by isolating them from corrosives in pipelines. They work in any position in both vacuum and pressure applications. These inexpensive isolators, readily available, eliminate blocked pressure and vacuum gauges by preventing suspended solids from clogging and causing faulty readings. Gauge guards are available without gauges (install your own) or with gauges pre-assembled.
