Keep a clean, leak-free seal with the Schaeffler O-Ring, part number SS0309. An O-ring is a simple loop-shaped seal that seats in a groove and is compressed between two mating surfaces to block the passage of fluid or air. This one is offered by Schaeffler as a replacement O-ring; no vehicle fitment is listed here, so check the Buyer's Guide tab to confirm the year, make, model, and engine coverage before ordering.
As a chassis-component specialist, Schaeffler supplies supporting hardware such as retaining clips, ABS cables, and bolts across its broader program to help with professional repairs; confirm exactly what is included with this specific O-ring before ordering. If a hardened, cracked, or leaking original O-ring is the cause of a seep at its joint, this part replaces it. Always diagnose the leak source before replacing.
