Industrial 0-200 Psi Liquid Filled Backmount Air Pressure Gauge

The Industrial 0-200 PSI Liquid Filled Backmount Air Pressure Gauge is a mechanical Bourdon-tube gauge designed to monitor pneumatic and hydraulic system pressure with reduced pointer vibration thanks to a liquid-filled case. It features a 2-1/2-inch dial and a 1/4-inch male NPT back-mount connection for straightforward installation in air compressors, pneumatic control systems, hydraulic equipment, water pumps, and other industrial process machinery where stable readings are essential. The liquid fill—glycerin or silicone—dampens pulsations for smoother operation in demanding environments, while wetted parts are brass or stainless steel and the case is stainless steel or steel, depending on the application. The lens can be polycarbonate or glass for clear visibility, and the scale is measured in PSI with typical accuracy of ±1.5% of full scale. Compatible media include air, water, oil, and non-corrosive fluids, making it suitable for a broad range of industrial uses. This gauge is commonly used by maintenance teams, technicians, and system integrators for pressure monitoring, replacement of damaged gauges, equipment maintenance, and system retrofits, offering a robust option for long service life in industrial pneumatic, hydraulic, and compressed air systems. Common replacements include WIKA 213.53, Ashcroft 1009, and Winters PFP Series gauges with the same 0-200 PSI, 2-1/2" dial, and back-mount configuration.
