EPDM & Viton® Isolators

Gauge Isolators
These devices are designed to replace the filter / snubber located in the fitting of most Perma-Cal® gauges.  The isolators are inserted into the fitting and the void within the Bourdon Tube and fitting are filled with a noncompressible fluid.  This technique 'isolates' the process fluid from the elastic element thus protecting the gauge internals from freezing, and contaminated fluids.  These can be ordered factory installed by specifying the options '-E' or '-V' or individually (uninstalled).  See the Isolator Bulletin for more details.

Reid Vapor Handle
These are optional handles that can be attached to any Perma-Cal® 4" flanged or no flange test gauge.  They are typically used to execute the Reid Vapor Tension method described in ASTM D323.  Specify a '-R' as an option in the part number.  See the Product Bulletin for more details.
