Like any element of the engine, oil seals are subject to wear. Over time they can lead to possible leaks of lubricating liquid.
A well-designed and properly installed front valve cover gasket can significantly improve engine efficiency by reducing oil leakage. This is because a faulty gasket can cause oil to seep out, leading to reduced oil pressure and poor lubrication of the engine's moving parts. Over time, this can cause significant damage to the engine, resulting in costly repairs or even premature engine failure.Seals are classified by O.D. wall material, lip type, and whether they have a spring or not.
Major oil seals are specified in ISO 6194-1 and JIS B 2402-1.
Table 2 shows the common types of oil seals, while Table 3 shows the features of each type of oil seal.
Table 4 lists the JTEKT oil seal type codes and corresponding ISO and JIS standards.
A: Existing molds: 30 days, depending on ordering quantity.
When choosing seal materials, it is critical to evaluate the environment and application. Common seal materials include:
When they are subjected to hot & pressured oil, or hot & pressured gas, they will compress. These seals reduce in size and become more compact. Afterward, they store the mechanical energy generated by the heat and pressure, which is why they can maintain a leak-proof mating surface.
