The US Gauge 1558 2-1/2" (63mm) Center Back Mount Liquid Filled Pressure Gauge - PSI & BAR (1558-2-1-2-PSI-BAR)] is built with a SST case, brass socket, and a phosphor bronze bourdon tube for applications that require the protection of liquid filling.
The 1558 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 protects the pressure gauge internally, and dampens the pointer to perfect readability. Liquid filling also abolishes 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. The gauge meets 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.
