One New Aftermarket Replacement Seal-Valve Stem for Caterpillar (Cat) Equipment
This aftermarket replacement valve stem seal fits Caterpillar (Cat) construction and heavy equipment engines. Valve stem seals are precision engine components mounted at the top of the valve guides in the cylinder head. They meter the amount of oil that lubricates the valve stem as it moves through the guide, preventing excess oil from entering the combustion chamber. Failed or worn valve stem seals can result in increased oil consumption, blue exhaust smoke, carbon buildup on valves, and reduced engine performance. Replacing a worn seal restores proper oil control and helps protect the valve train from premature wear.
