Installed between the engine cylinder block and cylinder head, it needs to withstand oil, refrigerant, and pressure and thermal shock of gas inside the cylinder. There are generally different structures with rubber pre-coated metal, rubber partial coated metal, and composite materials.

It is used at the connection of the turbocharger’s outlet to the hot end of the exhaust gas. Tightening the turbocharger with clamps or flanges to prevent high-temperature gas from leaking out, it has the advantages of good compensation and high temperature resistance. Generally are mica rings, metal rings, etc.

Used for various types of water pumps and oil pumps, there are rubber coated metal gaskets and pure rubber seals according to different application requirements.

According to different designs and usage areas, there are single-layer and multi-layer metal designs, as well as rubber pre-coated and partial coated material.

Used for the hot/cold ends, and various flange connection of the exhaust system. Generally, it has the characteristics of high temperature resistance, fatigue resistance, and corrosion resistance. According to different application requirements, there are single-layer and multi-layer metal designs, as well as designs that combine metal with high-temperature resistant graphite or mica.

EGR, exhaust gas recirculation system, is a system that sends a small portion of the exhaust gas generated by diesel or gasoline engines back to the cylinder for combustion. SIL provides metal gasket, gasket, rubber seal, and gasket with filter for EGR.

Used for the cold and hot ends of commercial vehicle rear processors, according to the design structure and fastening method of the flange, there are two designs: flat gasket and ring gasket, with various materials such as pure metal, metal with graphite, metal with mica, etc.

Air conditioning compressor gaskets and brake compressor gaskets, have similarities in appearance since rubber coated metal is commonly used. But because of completely different application conditions, the requirements for temperature resistance and corrosion resistance are also different when selecting material.

Used for sealing flanges on case covers, it comes in various materials such as non-metallic composite materials and asbestos free paper. Generally, it has a high compensation ability.
