There are significant differences in the requirements of different cars for gaskets, and these differences are mainly reflected in the following aspects

1. Material selection:

* Different cars have different needs for gasket materials. Some cars may need gaskets that are resistant to oil and chemical corrosion, while others may need gaskets that are resistant to high temperatures or high pressures. For example, high-performance cars may require gaskets that can withstand higher temperatures and pressures to accommodate their powerful engines and high-performance braking systems.

2. Performance requirements:

* Gaskets must have good physical and mechanical properties, including compression and resilience, to adapt to temperature and pressure fluctuations 
. Gaskets for high-performance cars may require higher heat and pressure resistance to accommodate higher operating temperatures and pressures.

3. Sealing medium:

* Gaskets need to be selected according to the nature of the sealing medium. For example, some gaskets may require good chemical resistance to specific fuels, coolants, exhaust fumes, or lubricating oils.

4. Operating conditions:

* The choice of gasket should also consider the operating pressure, operating temperature and working medium characteristics 
. For example, racing and military vehicles may require gaskets that can operate in extreme conditions, while the gaskets of ordinary passenger cars may not require such high pressure and temperature resistance.

5. Environmental requirements:

* With the strengthening of environmental regulations, some automobile manufacturers may prefer to choose gaskets made of environmentally friendly materials, such as asbestos-free gaskets.

6. Size and shape:

* The size and shape of the gaskets need to be customized according to the specific automotive parts. Different models and components may require different sizes and shapes of gaskets 
.

7. Safety and regulatory requirements:

* Certain regions or countries may have specific regulatory requirements, such as the prohibition of asbestos products, which will affect the choice of gasket materials.

8. Durability and life:

* High-end cars may pay more attention to the durability and life of gaskets to reduce maintenance costs and improve vehicle reliability
