magnetic drain plug

magnetic drain plug

A component of some lubrication systems in which metal particles in lubricating oil are attracted and collected. In some aircraft, magnetic drain plugs are connected to a warning light that comes on when magnetic particles are found. Metal particles in the lubrication system are a sign of impending internal failure of the engine. The system is similar to a chip detector system. See chip detector.
