A silicone gasket is a type of seal or barrier made from silicone, a synthetic rubber material. Silicone gaskets are popular due to their excellent resistance to heat, chemicals, and weathering. They are often used in industrial and automotive applications, such as sealing engine components and other machinery. Silicone gaskets can also be used in household appliances and plumbing fixtures to prevent leaks. They are also easy to install and maintain, and can withstand a wide range of temperatures.
