 Part 1: Function
1.Fill the micro pores between the cylinder block and cylinder head to ensure good sealing at the joint surface, thereby ensuring the sealing of the combustion chamber, preventing cylinder leakage and water jacket leakage, and maintaining the coolant and oil flow from the engine body to the cylinder head without leakage.
2.Sealing effect, increasing contact area, reducing pressure, preventing loosening, protecting parts and screws.
3.Usually, there are also flat washers used in connectors to increase the area of tightening force, which disperses the pressure on the nuts, protects the connection surface, or plays a role in locking, preventing loosening, etc.




Part 2: Types
1.The material of the gasket is generally not too hard.
2.Common gasket materials include metal, rubber, silicone rubber, fiberglass, asbestos, and so on. There are various types of gaskets, but they are usually divided into three categories: non-metallic gaskets, semi metallic gaskets, and metal gaskets.
