Liquid filled pressure gauges are perfect for On-Board-Air (OBA) applications.
The glycerin liquid inside enhances reliability and readability of the gauges by dampening the effect of vibration and pulsation which is very common on an OBA setup where a compressor is constantly pumping air. But liquid filled not only eliminates condensation buildup under the glass, the liquid filling extends the life of the gauge.
