Sierra 80180P Heavy Duty Electric Oil Pressure Gauge, 0-80 PSI, 2 Inch, 12V, Inboard and Diesel Engines

The Sierra 80180P is a heavy duty electric oil pressure gauge built for inboard and diesel marine engines. It reads across a 0 to 80 PSI range on a 2 inch gauge face, making it easy to monitor engine oil pressure at a glance from the helm. The gauge runs on a 12 volt electrical system and uses an electric sending unit design rather than a mechanical capillary line, simplifying installation and routing compared to older mechanical gauges.

Construction combines aluminum and stainless steel components suited to the marine environment, where corrosion resistance and long-term durability matter. At 0.32 pounds, the gauge is lightweight and straightforward to panel-mount alongside other engine instrumentation. As a genuine Sierra part, it is backed by Sierra's customer satisfaction warranty, which covers the product against defects in workmanship and materials for its useful life, with repair or replacement if a covered defect occurs.
