C9452 Carburetor to manifold spacer block o-ring

This Cometic O-ring is designed specifically for the carburetor-to-manifold spacer block on vintage Harley-Davidsons. It is a direct replacement for OEM 11107 and is used on 1966 to early 1971 FL and Sportster models equipped with the original Tillotson carburetor. These models typically require two of these O-rings to ensure a proper airtight seal at the intake. Preventing air leaks is crucial for maintaining a steady idle and proper fuel mixture on these classic machines. Cometic’s high-quality rubber construction ensures these O-rings stand up to the intense heat and fuel exposure common in the intake tract, providing a long-lasting seal for your vintage fuel system.
