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.
