Viton® is a brand name of DuPont for its synthetic rubber and fluoropolymer elastomer, commonly used in O-rings and other moulded or extruded products. It provides the best fluid resistance of any commercial rubber. With its low permeability to such a broad range of substances, Viton® is known to deliver exceptionally good performance in oxygenated automotive fuels.
