DNJ Engine Valve Stem Oil Seal Set - VSS1122

DNJ Engine Valve Stem Seal Sets are precision-engineered to control lubrication and prevent oil from leaking into the combustion chamber. Each set includes intake and exhaust valve seals for every cylinder, ensuring consistent sealing performance across the entire valvetrain. Designed to fit precisely with OEM specifications, these sets are essential for any complete engine rebuild or top-end service. DNJ Engine Valve Stem Seal Sets are manufactured using high-performance materials selected for their durability under extreme conditions. The sealing elements are made from advanced elastomers such as Viton, polyacrylate, or nitrile rubber—each chosen for specific resistance to high temperatures, oil degradation, and chemical exposure. The outer shell is formed from carbon or stainless steel for structural integrity and corrosion resistance. An integrated spring maintains uniform pressure around the valve stem to ensure long-term sealing efficiency. All DNJ valve stem seals are manufactured to meet or exceed OEM quality standards, delivering a reliable fit and function in demanding engine environments. DNJ also offers a wide range of related components—including valve cover gaskets, complete cylinder head gasket sets, valve guides, engine valves, and more—to support complete valvetrain service. With precision engineering and top-tier materials, DNJ Engine Valve Stem Oil Seals deliver exceptional performance and long-lasting durability.
