Glycerin Filled Pressure Gauge 1-100 PSI – Bulk Reef Supply

$20.49

The Glycerin filled pressure gauges are our preferred gauge.  Compared to an air-filled gauge they will be much quieter as water has a tendency to vibrate when running, as well as lasting much longer as the oil in the gauge will soak up the vibrations which can cause excessive wear on air-filled gauges.
