Metal gasket

effect:

1. In screws with nuts, the function of the gasket is to increase the contact area, reduce the pressure, and protect the parts and screws;

2. Gasket refers to a material made of paper, rubber sheet or copper sheet and placed between two planes to strengthen the seal. It is a sealing element placed between the static sealing surfaces to prevent fluid leakage;

3. A gasket is a mechanical seal between two objects. It is usually used to prevent pressure, corrosion, and leakage from the natural thermal expansion and contraction of the pipeline between the two objects. Since machined surfaces are never perfect, irregularities can be filled in using shims. Gaskets are typically made from sheet materials such as paper, rubber, silicone, metal, cork, felt, neoprene, nitrile, fiberglass, or plastic polymers (such as Teflon). Gaskets for certain applications may contain asbestos.

The cylinder gasket is mainly used to ensure the sealing between the cylinder block and the cylinder head joint surface to prevent air and water leakage. It is one of the most important gaskets in automobiles, and it is also the most easily damaged gasket. The gasket in the engine has a sealing function.

Generally, screws with nuts are fixed in through holes. The diameter of the through holes is generally slightly larger than that of the screws. Therefore, spacers are needed to increase the contact area. Protect parts. Lock parts, reduce pressure, protect parts and screws.
