A shaft oil seal, also known as a lip seal, is typically made of rubber or other flexible materials, with a lip that seals against the rotating shaft. It is designed to effectively seal the interface between the shaft and the housing, preventing the entry of dirt, dust, water, and other contaminants that could potentially damage the machinery.
The temperature within the oil seal environment is the main factor that dictates the composition of an oil seal. Generally, there is a range of set temperatures that are optimal for that material. If the operating environment is too cold, the seal may become brittle and, at high temperatures, the seal material may show increased elasticity and become leaky.

Table 6 shows how to select the metal case and spring materials.

In plumbing systems, square rubber gaskets are frequently employed in pipe connections, preventing water leaks and ensuring a secure fit. They are also found in engine compartments, sealing joints and preventing oil or coolant leaks They are also found in engine compartments, sealing joints and preventing oil or coolant leaksIts sealing edge comes in full contact with the shaft surface in order to provide excellent sealing performance.
(See Figure 3.)
If these specific tools aren’t available, it’s entirely possible to correctly seat an oil seal in its housing using a hammer. Ideally, this hammer will be plastic or rubber due to it’s more forgiving nature. Using this and a strike plate that covers the entire seal will lend you accuracy while driving it in. The downside to this method is the inability to drive the seal any further than the strike plate will allow.
