A gasket is a mechanical seal that fills the space between two or more mating surfaces to prevent leaks. Made from materials like rubber, metal, or silicone, it is often used in engines, pipes, and machinery where tight seals are essential to prevent fluid or gas leaks.

Gaskets are made from a variety of materials, each suited for specific applications. Common materials include rubber, silicone, cork, metal, and composite materials. The choice of material depends on factors like temperature, pressure, chemical compatibility, and the type of fluids being sealed.

Choosing the right gasket depends on factors like temperature, pressure, chemical exposure, and flange design. For example, high-temperature environments require materials like graphite or metal, while corrosive chemicals might need a gasket made from resistant materials like PTFE.

Gaskets are essential in many industries, including automotive, aerospace, oil and gas, and pharmaceuticals. In these sectors, gaskets ensure tight seals in engines, piping systems, machinery, and various devices to maintain safety and performance by preventing leaks and contamination.
