2. Metal Case
Lay out the pieces of the new gasket on clean newspaper, and note how the joints fit.
The oil seal should be tough enough to withstand the pressure and the vibrations caused by the shaft and bore. Check if the oil seal is strong enough to tolerate the pressure and vibration.
Among the most common causes of oil seal failure are:


Conventional oil seals
The metal case is the exterior (or frame) of the oil seal, the principal function of which is to give rigidity and strength to the seal. The material of the case must be selected depending on the environment where the seals are to be used. Often the metal case is covered by the same rubber material used in the sealing element, which also helps seal the exterior of the oil seal in the housing bore. Common case material types are:
Oil seals for cars
Engine oil seals are vital components in the automotive engine system, designed to prevent the leakage of lubricating oil and the ingress of contaminants. These seals play a critical role in maintaining the proper lubrication of the engine components, including the crankshaft, camshaft, and other critical parts. Engine oil seals contribute to the efficiency and longevity of the engine by preventing oil leaks and ensuring optimal performance.
Conventional oil is the most commonly used type of oil. It is ideal for light-duty, late-model cars with low to average mileage and a simple engine design.
Despite being a great substitute for more expensive high temperature resistant materials, polyacrylate has a problem of poor water compatibility and cold flexibility.
