Copper asbestos pad gasket
Copper asbestos pad, it has the characteristics of high pressure and high temperature resistance. It is generally suitable for engine cylinder pad. When it is used, it must first remove the dust and dirt on it, and pay attention to the side of its copper flange to face the cylinder head. On one side, prevent reverse air leakage.
Paper pad gaskets
Paper pad we will still be common in life, its role in two ways, the first is to increase the sealing, and the second is used to adjust the gap between components.
The role of gasket flat mat
The function of the flat pad is to allow the pressure of the nut to be distributed over the pressure member, and also to protect the surface of the screw thread and the connecting body. General thin metal shells are fixed with metal flat washers.

The role of copper flat washers
The material of the copper flat mat is generally made of copper material, and most of them are used in places with high pressure, such as gaskets of injectors.
The role of cork gaskets
Cork mats have a certain degree of toughness and are generally used between a water tank, an engine oil pan, and the body. The cork mat is soft and has good sealing performance, which reduces the vibration, collision and wear of the parts. The weakness is crunchy and fragile.
The role of spring washers
The spring washers are used to connect the bolts and prevent the bolts and nuts from loosening due to shock. Especially spring bolts should be used for bolts that are not easily visible or difficult to handle.

The role of asbestos pad gaskets
Asbestos pads are characterized by high temperature resistance, so the parts used are high temperature parts, such as between the exhaust pipe and the cylinder head, and these parts cannot be replaced with other gaskets.
The role of rubber gaskets
The rubber pad is made of two kinds of materials, one is a gasket made of a non-oil-resistant material for sealing the air, such as a gasket used on the air cleaner case; the other is made of an oil-resistant raw material for sealing the oil. Gaskets, such as rubber pads on both ends of a diesel engine oil filter. When using, it should be noted that oil-resistant pads can replace non-oil-resistant pads, and non-oil-resistant pads cannot be used in place of oil-resistant pads. In the long-term use of the rubber mat, if it is found to lose its elasticity, it should be replaced in time to avoid wearing parts.
The role of felt pad gaskets
The felt pad has a certain degree of wear resistance and shock absorption, and is generally used at the bottom of a thin metal box or at a hoop, such as the bottom of a diesel box.
