A "가스켓" (gasket) is a mechanical seal used to fill the space between two or more mating surfaces. Its primary purpose is to prevent leakage of fluids or gases, ensuring a tight seal in various applications. Gaskets are commonly made from materials like rubber, metal, or composite materials, depending on the specific requirements of the application. Gaskets are widely used in industries such as automotive, aerospace, and manufacturing. They can be found in components like engines, pumps, and valves, where they help maintain pressure and prevent contamination. Proper installation and maintenance of gaskets are essential for optimal performance and safety.
