The Cometic C9395 is a precision-engineered replacement gasket designed for the oil pump relief pipe (also known as the crankcase breather relief pipe) on Harley-Davidson flathead motorcycles. This gasket fits Big Twin flathead models from 1937-1948 and 45 cubic inch flathead models from 1937-1973, including U, UL, WL, WLA, and WLC models. It replaces OEM part number 24921-37.

Key Features:

• Manufactured from premium fuel-resistant materials designed for long-term reliability
• Engineered to prevent oil leaks at the relief pipe mounting surface
• Will not creep, crack, or become brittle over time
• Precision die-cut for accurate fitment
• Made in the USA by Cometic Gasket, a trusted leader in high-performance gasket technology

This gasket seals the relief pipe to the cam cover or crankcase, preventing oil seepage and maintaining proper crankcase ventilation. Essential for restoration projects and routine maintenance on vintage Harley flathead engines.
