F30 F20 G20 G30 BMW oil line O-ring 16x2mm - 1142860487212

Replacement 16x2mm O-ring for BMW oil lines on F30, F20, G20 and G30 chassis. Fixes weeping or seepage at the oil line connection - a common early sign of seal fatigue.

• Exact fit for factory oil line joints; no trimming or forcing needed
• Made from oil- and heat-resistant nitrile rubber - withstands repeated hot-cold cycles
• Direct swap for worn, flattened or brittle originals
• Part number 1142860487212 - matches OEM spec, not an imitation

Use during routine service or when chasing down a minor oil trace. Not a performance mod, but one of those small jobs that keeps your fast-road or track-day Bimmer running cleanly.
