Description
Valve stem seals are critical for controlling oil consumption and preventing blowby in high-performance engines. Worn or degraded seals allow oil to migrate past the valve stem into the combustion chamber, resulting in excessive smoking, carbon buildup, and lost power. These PTFE valve seals deliver a precision fit and reliable positive stop to maintain proper oil control across extended racing and street applications.
