PCM O-Ring Part #22800

This genuine PCM OEM O-ring is a precision sealing replacement for Pleasurecraft Marine inboard engines. O-rings are used throughout the engine and its supporting systems fuel, cooling, oil, and raw water circuits to create leak-free seals at fittings, housings, pumps, and connections. Using the correct OEM O-ring ensures the right inner diameter, cross-section, and elastomer compound for a reliable seal under the temperature and pressure conditions of your specific application.

An aftermarket O-ring of the wrong compound or dimension can swell, shrink, or extrude under pressure, leading to leaks that are difficult to trace. The OEM part eliminates that risk.

Parts Desk Insights

Best use case: This O-ring is most commonly needed when resealing a fitting, housing, or pump connection during a service or when tracking down a weep or seep that appears after a component has been disturbed. O-rings are single-use items: once a seal has been broken and the O-ring compressed or twisted, it should always be replaced rather than reused. At this price point, ordering a spare to keep on hand during any fuel system, cooling system, or oil system service is always worthwhile.
