Yellow Jacket 49511 LIG FILL PRESSURE GAUGE

The Yellow Jacket 49511 is a robust, glycerin liquid-filled analog gauge, primarily used in manifold gauge sets for servicing R-22-based systems. The liquid filling helps protect the gauge from internal pulsation and vibration, which extends its life and ensures steady readings. It features a large dial with color-coded temperature and pressure scales for easy reading. The gauge is intended for the high-side (red) pressure measurement of a manifold.
