Description
Genuine Harley-Davidson O-ring (P/N 11120) fitted to the engine oil fill cap and dipstick. A hardened or flattened O-ring is a common cause of oil weeping around the filler neck; replacing it restores a clean, positive seal.
Made from oil-resistant rubber to factory specification. Sold individually. Recommended whenever the dipstick O-ring is removed or at every oil change if any seepage is noted.
Fitment: Commonly listed for 2004-2022 Sportster models. Check fitment with our parts team.
