There are several types of automotive seals, including:

1. O-rings: circular seals that fit into a groove and compress when the two halves of a joint are bolted together.

2. Gaskets: flat seals made from materials such as rubber, cork, or metal that are placed between two surfaces to prevent leakage.

3. Lip seals: dynamic seals that use a flexible lip to seal against a moving surface, such as a shaft or piston.

4. Mechanical seals: seals that use a stationary and a rotating component to create a barrier between two fluids or gases.

5. V-ring seals: seals that have a tapered cross section and are used to seal against a shaft or housing.

6. Oil seals: seals that prevent the leakage of lubricants or other fluids from a rotating shaft or other moving part.
