The 0–160 PSI Glycerine Filled Pressure Gauge is a durable, industrial-grade pressure monitoring gauge designed for accurate measurement of air and water pressure in professional water purification systems, reverse osmosis installations, booster pump assemblies, and window cleaning equipment. Featuring a clear 0–160 PSI pressure range, this glycerine-filled pressure gauge provides stable and precise readings by reducing needle vibration and pulsation, making it ideal for systems where pressure fluctuations can affect accuracy. Equipped with a 1/4" male threaded inlet, the gauge offers straightforward installation into a wide range of RO systems, DI setups, pumps, and filtration equipment.
