Valley Industries 2.5" Liquid Filled Gauge, Dual Scale, 160PSI | 2140GXB160
These gauges are designed for use with any medium not corrosive to brass or bronze. Liquid filling adds to the life of a pressure gauge. When the case is filled with a dampening fluid, the internal components are protected from outside contaminants, providing continuous lubrication for the tube and movement reducing the shock waves caused by vibration or pressure fluctuations and virtually eliminating pointer flutter. It should not be used in conjunction with oxygen service or other explosive agents.
When choosing a pressure range you should choose one that is twice the normal system pressure. Example: if system runs at 50 PSI you should choose a 100 PSI gauge. This will make the gauge safer, last longer, and be more accurate.
