Underhill Pressure Gauge w/Schrader Valve Adapter and Flex Hose
Use this 160 PSI liquid filled pressure gauge with Schrader valve adapter on flex hose to test or adjust pressure regulated valves in your system. Convenient to use for quick checks on any component with a Schrader valve.
Please Note: An air bubble is normal in all liquid filled pressure gauges to allow for expansion and contraction of the oil. Over time or transportation some oil may leak out or evaporate due to environmental conditions. This will not harm the gauge. The liquid is used as a buffer or cushion for the needle (reduces vibration) which provides for a more accurate reading.
