This is the o-ring typically used to seal oil cooler hoses to the oil cooler. Over time the rubber shrinks or becomes brittle and an oil leak develops. New lines or a new oil cooler are not always required when it's one of these basic o-rings. A simple fix to stop an aggravating leak!

This o-ring is used on nearly all factory BMW oil coolers and lines since the 1980s, including: E30 M3, E36 M3 Euro, E46 M3, E90/E92 335i/M3, F30 335i, F32 435i, E60 M5, E63 M6, and others.
