Gaskets are mechanical components used to create a seal between two or more surfaces, preventing the leakage of fluids or gases. They are designed to fill irregularities and imperfections in mating surfaces, ensuring a tight and secure connection. Gaskets are commonly made from materials such as rubber, silicone, cork, metal, or composite materials, chosen based on factors like temperature, pressure, and the nature of the substances they need to seal. Gaskets are essential in a wide range of industries, including automotive, manufacturing, aerospace, and plumbing, where they play a critical role in maintaining the integrity and safety of various systems by preventing leaks and ensuring proper containment of fluids or gases.
