Genuine BMW Oil Line O-Ring – OE 11421702905

Description

Genuine BMW 11421702905 is an original BMW oil line O-ring designed to provide a leak-free seal for the engine oil system.

Manufactured to BMW's exact specifications, this seal ensures reliable oil pressure and long-lasting sealing performance. It is recommended whenever the oil filter housing, oil cooler or oil lines are removed to prevent future oil leaks.

A worn O-ring can cause:
✔️ Engine oil leaks
✔️ Oil residue around the oil filter housing or oil cooler
✔️ Low engine oil level
✔️ Loss of oil pressure if left unrepaired

Recommended during:
✔️ Oil filter housing repairs
✔️ Oil cooler replacement
✔️ Oil line removal
✔️ Turbo oil line service (where applicable)
✔️ Engine rebuilds
