About This Product
This James Gaskets O-ring is a versatile seal used on the crankcase drain plug for a wide range of modern liquid-cooled Harleys. It is a direct replacement for OEM 11900045 and is essential for preventing oil drips after a service. This single O-ring fits 2021 to 2024 Pan America models, including the Special, CVO, and ST variants, as well as 2021 to 2025 Sportster S and 2022 to 2025 Nightster models. It also fits the 2015 to 2020 XG750 and XG500 Street series. It’s a small but vital part to keep in your toolbox for every oil change.
Manufacturer part number: ST-11900045.
