Cylinder Head Gasket

Engine cylinder head gasket, abbreviated as cylinder gasket, is an elastic sealing element placed between the cylinder block and the cylinder head. Due to the impossibility of absolute flatness between the cylinder block and head, cylinder head gaskets are required to prevent high-pressure gas, lubricating oil, and cooling water from escaping between them.

The gasket are made of a reinforced graphite sheet or asbestos sheet or non asbestos sheet by punching or pressing, depend on its excellent corrosion protection, high-and-low temperature resistance, fine compression resilient the product is widely applied as cylinder head seals of automobile engine, diesel engine, air compressor, refrigerating machine, etc.

The function and characteristics of cylinder head gasket
The cylinder head gasket is a component located between the cylinder head and the engine block, which plays a sealing role. Compared to cylinder gaskets, cylinder head gaskets are relatively simple, and their main functions are:
1. Prevent seal damage
The main function of the cylinder head gasket is to seal the gap between the cylinder and the cylinder head, effectively preventing liquid from mixing with each other.
2. Ensure normal operation
During the operation of the engine, the pressure will continuously compress the gas and liquid, and the temperature will also continue to rise. At this time, the cylinder head gasket can play a role in limiting gas and liquid leakage, ensuring the normal operation of the engine.
3. Resistance to high temperature and high pressure
The pressure and temperature that the cylinder head gasket needs to withstand are relatively low, generally requiring no less than 230 degrees, and it is usually made of non-metallic materials to improve its ability to withstand high temperature and high pressure.
