The rubber gasket in the exhaust manifold gasket has several advantages:

1. Good sealing performance: the rubber gasket has good elasticity and plasticity, can adapt to different shapes of joint surfaces, and provides good sealing effect. Rubber material can form a good seal on the contact surface, prevent the leakage of gas and liquid, and ensure the normal operation of the exhaust system.

2. High temperature resistance: Rubber gaskets are usually made of high temperature resistant materials such as silicone rubber, fluororubber or nitrile rubber. These rubber materials have good high temperature resistance and can maintain stable performance in high temperature environment. In the exhaust system, the rubber gasket can withstand the impact and thermal radiation of high-temperature gas and maintain good sealing performance.

3. Chemical resistance: Rubber gasket has good chemical resistance and can resist the corrosion of chemicals such as oil, gasoline and coolant. In the exhaust system, the rubber gasket can bear the acidic and alkaline substances in the exhaust gas and will not lose its sealing performance due to chemical corrosion.

4. Good wear resistance: The rubber gasket has good wear resistance and can resist the abrasion of particles and particles in the exhaust gas flow. They can maintain a long service life and reduce the frequency of replacing gaskets.

5. Vibration reduction and sound insulation effect: Rubber gasket has certain elasticity and vibration reduction performance, which can absorb and reduce the vibration and impact force in the exhaust system. They can provide a more stable and quiet driving environment and reduce the impact of noise and vibration on vehicles and passengers.

To sum up, the rubber gasket in the exhaust manifold gasket has good sealing performance, high temperature resistance, chemical resistance, wear resistance and vibration and sound insulation effects. These advantages make rubber gasket become one of the common sealing materials in exhaust system, which can ensure the normal operation and reliability of exhaust system.
