Glycerin Liquid Filled Pressure Gauge, Back Mount, 0-100 PSI

The Zenport BLPG100 Glycerin-Filled Pressure Gauge measures pressure from 0–100 PSI in irrigation systems, HVAC equipment, and other pressure-monitoring applications. Its 2.5-inch ABS case features brass internals, a durable plastic window, and a 1/4-inch NPT back connection for installation. The glycerin-filled design helps reduce needle vibration caused by pressure fluctuations, providing steadier, easier-to-read measurements in high-vibration environments. With Grade A accuracy of 1.6%, this gauge is suitable for professional and general-purpose pressure monitoring.
