The function of the washer is to protect the surface of the connected part from being scratched by the nut, and to disperse the pressure of the nut on the connected part. The washer refers to the part that is cushioned between the connected piece and the nut, and is generally a flat metal ring.

There are many types of gaskets, different sizes and thicknesses, and different materials, and their roles are different.

1. Copper-skin asbestos gasket: Copper-skin asbestos gasket has the characteristics of high pressure resistance and high temperature resistance, and it is used for engine cylinder gaskets.

2. Paper pad: There are two uses for it. One is to increase the sealing performance to prevent oil leakage; the other is to adjust the gap between the components.

3. Flat washer: Its function is to evenly distribute the pressure of the nut on the pressure part through the flat washer, and at the same time protect the surface of the bolt thread and the connecting body.

4. Aluminum flat gasket: Aluminum flat gasket has a certain degree of toughness, and it can be used in the joints of diesel and engine oil pipelines.

5. Copper flat gasket: The copper flat gasket is generally made of red copper, which is mostly used in parts with high pressure, such as the gasket of the fuel injection nozzle.

6. Cork mat: Cork mat has a certain degree of toughness and is generally used between the water tank, the engine oil pan and the body.

7. Rubber pad: The rubber pad is made of two kinds of raw materials, one is a gasket made of non-oil-resistant raw materials for sealing the air, such as the gasket used on the air filter housing; the other is used for oil-sealing parts Gaskets made of oil-resistant materials, such as rubber gaskets at both ends of diesel oil filters.
