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.


Sufficient PSI is very important for the correct operation of a reverse osmosis unit. Low water pressure is a leading cause of poor RO system performance. A pressure gauge assures that proper pressure is being supplied. It will also make pressure drops apparent which can tell you that sediment and carbon blocks need to be changed.

Glycerin filled pressure gauges absorb vibration and pressure spikes increasing service life. This glycerin filled pressure gauge comes assembled with 1/4" quick connect fittings for quick easy installation in-line before the RO Membrane. This item is designed for use with our saltwater aquarium line of RO systems.
