Pressure Gauge Guards

The Penguin plastic gauge guard is a unique, compact, molded design consisting of two threaded fluid chambers. There is no possibility of leakage due to uneven screwed components. Each piece contains a matching groove which confines the true o-ring incorporated on the OD of the impermeable diaphragm. A bleed plug and o-ring are included in the design for proper filling or the incompressible liquid in the gauge side chamber. This prevents air entrapment, thus providing an accurate reading with no needle vibrations.
