How and why are gaskets used?

Gaskets are used to create a seal between two or more surfaces to prevent leaks of fluids or gases in mechanical systems. They are crucial in applications like engines, pipelines, and various machinery where pressure and temperature variations occur. The material and design of gaskets are chosen based on the specific requirements of the application, such as resistance to temperature, pressure, and chemical exposure. By providing a reliable seal, gaskets enhance the efficiency and safety of machinery and prevent costly leaks and damage.
