Only the best for one of the most critical areas in the engine! Minimal wear is the result of over 60 years of experience in this area of the engine gasket. Metal-reinforced stem seals with Viton coated insides ensure excellent sliding and sealing properties and are suitable for maximum valve lifts. KPMI Red valve stem seals withstand the highest engine temperatures and are corrosion and acid resistant. Where other gaskets harden and oil can penetrate unhindered into the combustion chamber, these versions remain tight for a long time! Metal-reinforced versions .420" x .310" in a set of 4.
