Gasket material is a type of material used to create a seal between two surfaces, preventing leaks of fluids or gases. Commonly made from rubber, cork, or metal, gaskets are essential in various applications, including automotive engines and plumbing systems. They help maintain pressure and protect against contamination. The choice of gasket material depends on factors like temperature, pressure, and the type of fluid involved. For instance, silicone gaskets are often used in high-temperature applications, while PTFE (Teflon) gaskets are suitable for chemical resistance. Proper selection ensures optimal performance and longevity of the equipment.
