40mm 1 bar Axial Mounting Stainless Steel Pressure Gauge Glycerin Filling
Description
To put it simply, liquid filling a pressure gauge is strictly used as an inexpensive way to steady the needle and lubricate the internals of a gauge during applications with vibration. The most common fill fluids used are Glycerin and Silicone. Glycerin is used in around 95% of all liquid filling applications and is typically the “standard.” The reason these fluids are used is because they’re more viscous and their thickness helps keep the needle steady. Some gauges come dry but can be filled simply by filling the hermetically sealed gauge case through the fill port (usually at the top) and then reinserting the fill plug when finished.
