Camshaft Seal

DNJ Camshaft Seal

DNJ® Engine Oil Seals are essential components designed to prevent engine oil leakage and block harmful contaminants from entering critical areas of the engine. These precision-engineered seals are commonly installed at the crankshaft, camshaft, or balance shaft exits to maintain oil integrity and promote long-lasting engine performance. Each oil seal features a primary sealing lip, metal case, and spring-loaded tensioner, with some designs including an additional dust lip for enhanced protection.

 DNJ® Engine Oil Seals are made using premium materials selected for their durability and resistance to extreme operating conditions. The sealing lip is crafted from advanced elastomers such as nitrile rubber (NBR) or fluoroelastomer (FKM/Viton®), providing excellent resistance to oil, heat, and chemical degradation. NBR is often used in standard applications, while FKM is used in high-temperature and turbocharged environments. The metal case, made from high-strength carbon or stainless steel, provides structural rigidity and ensures a secure fit within the engine housing. A high-tensile garter spring made of corrosion-resistant spring steel maintains consistent radial pressure on the shaft for reliable sealing. Each component is manufactured to meet or exceed OEM quality standards for superior function and fit.

DNJ® also offers a wide range of related gaskets and sealing components, including rear main seals with or without retainers, valve stem seals, timing cover gasket sets, and complete gasket sets to support full engine rebuilds. With precision engineering and top-tier materials, DNJ® Engine Oil Seals deliver exceptional performance and long-lasting durability.
