A gasket is a mechanical sealing component used to prevent leakage between two joined surfaces. It is placed between machine parts such as engine blocks, pipe flanges, pumps, and valves. The main purpose of a gasket is to stop the leakage of liquids, gases, or pressure. Gaskets are made from different materials like rubber, cork, metal, silicone, graphite, and asbestos. The selection of gasket material depends on temperature, pressure, and the type of fluid used in the system. There are different types of gaskets such as: Soft gaskets Metallic gaskets Spiral wound gaskets Ring gaskets A good gasket should be flexible, heat-resistant, and durable. In automobiles, head gaskets are very important because they seal the engine combustion chamber and prevent oil or coolant leakage. Thus, gaskets play a vital role in machines and industrial equipment by ensuring safety, efficiency, and proper sealing.
