Description
Valve stem seals are critical components that prevent oil from leaking past the valve guides and into the combustion chamber—a problem that leads to blue smoke, increased oil consumption, and accelerated wear on catalytic converters. The COMETIC C9424-1 delivers the reliability you need for long-term engine health, whether you’re building a race engine or restoring a classic. Manufactured in the U.S.A. from premium, fuel-resistant elastomers, these seals resist creep, cracking, and brittleness across a wide range of operating conditions.
