There are many different materials used to manufacture oil seals.
Raise the front of the car on ramps, apply the handbrake and chock the rear wheels. Clean round the sump and the crankcase , clutch and gearbox. Drain the engine oil (See How to drain engine oil and remove filter ). Use an adequate jack to lift the engine.

Leather oil seals are commonly used for parts that are exposed to dirt and poor lubrication. The major advantage of this material is that it can function in cases where synthetic rubber cannot function. They are used for shafts that have rough surfaces that are more than what rubber seals can handle. This is because they are pre-lubricated and have the capacity to absorb liquids.
What are Oil Seals - Guide to what an Oil Seal is used for
The lip is specially designed to ensure the oil seal works effectively with the different forces that arise during rotation. Many different designs and materials are used, so countless types of oil seals are available. These are chosen according to the application; pumps, gearboxes, wheels, and many other rotating applications where fluids need to be sealed. They are used in a variety of sectors, such as the chemical industry, manufacturing, wind turbines, automotive sector, food industry, and more. Oil seals are used in nearly all sectors.

Before installing the oil seal, it is important to lubricate it to reduce friction and prevent damage during installation. A silicone-based lubricant is recommended for most applications. If the oil seal is to be installed in a high-temperature or high-pressure environment, a more specialized lubricant may be required.
Rotary shaft or oil seals are placed between moving and stationary pieces of machinery to ensure that contaminants, moisture, corrosive materials and abrasives do not damage the various components. They can also prevent unwanted mixing of fluids, including water and oil combining within a machine.
A wide range of sealing devices are used in various machines.
Sealing devices serve the following functions:
3. Fluid types: Oil seals interact with oils, fuels, grease, water, and more. Choosing a seal material that is most compatible with your chosen medium can help to increase the durability of the seal and its internal components.
