Viton rubber gaskets are known for their exceptional chemical resistance, particularly against aggressive substances such as fuels, oils, and a wide range of acids and solvents. They also perform well in extreme temperatures, withstanding both high heat and low cold environments. Viton is widely used in automotive, aerospace, and chemical industries due to its durability and resistance to compression set, making it ideal for seals, O-rings, and gaskets in demanding environments
