Magnetic Drain Plug

The MILODON Magnetic Drain Plug (Part No. 17000) is a precision-engineered component designed to trap ferrous metal particles in engine oil, extending drain intervals and protecting internal engine components from wear. With a 1/2-20 inch thread and magnetic steel construction, this drain plug captures microscopic iron filings that would otherwise circulate through the lubrication system, reducing friction-related damage and extending overall engine life.

The magnetic drain plug features a cadmium-plated steel body that resists corrosion in harsh environments, while the included brass crush washer ensures a reliable, leak-free seal on every installation. The 1/2-20 thread size is a common specification across automotive, marine, and industrial engine applications, making this plug compatible with a wide range of oil pans and sumps. The magnetic core works passively—requiring no maintenance or power input—continuously collecting ferrous debris as oil circulates through the engine.

This drain plug is essential for high-performance enthusiasts, fleet operators, and anyone running extended drain intervals who wants to monitor and minimize internal engine wear. Whether used in automotive engines, small-block V8s, marine applications, or industrial equipment, the MILODON magnetic drain plug provides real-time particle collection that standard drain plugs cannot match. Simply remove during regular oil changes, wipe clean, reinstall with a fresh crush washer, and continue engine protection.

Magnetic drain plugs have become standard issue in serious engine building and maintenance because they reveal wear patterns and protect against undetected internal damage. The cadmium plating and brass washer combination ensures durability across repeated installation cycles, while the magnetic core remains effective across the full temperature range of engine oil operation.
