These 4" liquid filled pressure gauges have large dials for easy readablity. A protective stainless steel case with 1/2" bottom mount brass connections, bourdon tubes and movements make them useful in water, oil, gas (WOG) and hydraulic applications. Glycerin oil lengthens the life of the manometer by reducing internal vibration and lubricating the gauge's internals.
Manufactured by DuraChoice, the gauges are available in ranges from vacuum to 15000 PSI, they are good for many media, including water, oil, diesel or gas.
