A gasket is a mechanical seal that helps to prevent leakage between two or more surfaces. It acts like a puzzle piece, fitting snugly into the gaps and irregularities of the mating surfaces, ensuring a tight and secure connection. Just like a well-designed puzzle, a gasket's shape and material are crucial for creating an effective barrier against fluids, gases, or contaminants. It works in harmony with other mechanical components, like a trusty tool in a toolbox, providing essential sealing functionality to various systems and applications.
