Engine cylinder head gasket is an auto part that plays a role of sealing. There are two common classification products for this auto part currently on the market, so what are the main two common classifications? Next, I will give you a brief explanation, and hope you can deepen your understanding of it.
The two engine cylinder gasket products currently on the market are mainly classified according to different materials, namely metal asbestos gasket and metal gasket. Metal asbestos pads are made of asbestos as the main raw material, and the outer surface is made of copper or steel. Some of the products use braided steel wire or perforated steel as the skeleton, and some products are made of metal rings around the cylinder bore. The main purpose is to increase the strength of the product. Its advantage is that the price is lower, but the strength is relatively poor, and because asbestos has carcinogenic effects on the human body, it has been discontinued in developed countries. The metal pad is made of a whole piece of steel plate, and there are elastic ridges on the surface of the product. In use, the elasticity of the ridges and the function of the heat-resistant sealant are used to achieve the sealing effect.
