The US Gauge 1559 1-1/2" (40mm) Center Back Mount Liquid Filled Pressure Gauge - PSI/BAR/KPA (1559-1-1-2) is crafted with a SST case, brass socket, and a phosphor bronze bourdon tube for applications that need the protection of liquid filling.
The 1559 liquid filled gauges have a crimped ring and dual scale psi/bar or kPa/psi dial as standard. The pressure gauge is key for environments with high vibration, pulsation, pressure spikes and condensation build up. Liquid filling guards the pressure gauge internally, and dampens the pointer to better readability. Liquid filling also eliminates condensation build up due to temperature fluctuations on the inside window. The case is material is 304 SST with a crimped on window and a liquid fill plug at the top of the case for simples field filling if needed. ASME B40.100 Grade B accuracy (±3-2-3%) and is NEMA 4X / IP66 compliant to increase the life of your pressure gauge. Pressure ranges are from Vacuum to 10 000 psi.
