KPMI 71040-4 Red Viton Valve Stem Seals, 4-Pack

KPMI® solid Viton® valve stem seals are designed to have optimum fitment, allow for maximum lift, and to give maximum life. KPMI® Red valve stem seals are resistant to high temperatures, petroleum products and the corrosive gasses that are the by-products of combustion. These seals retain their ability to seal in situations where other materials could harden and allow oil to enter the combustion chamber causing detonation, carbon build up and a loss of power. The Red Ones are truly the racer’s choice.

KPMI 71040-4 solid Viton valve stem seals are designed to provide optimum fitment, accommodate maximum lift, and deliver long service life. Their red Viton construction is resistant to high temperatures, petroleum products, and corrosive gases produced during combustion.

These valve stem seals are designed to retain their sealing ability in conditions where other materials may harden. By helping prevent oil from entering the combustion chamber, they can help reduce the conditions associated with detonation, carbon buildup, and power loss. The KPMI Red valve stem seals are suited to performance-focused applications.
