Viton O-Rings are O-Rings made of the synthetic rubber Viton, trademarked by the DuPont Performance Elastomers LLC. Viton is the most common flouroelastomer used to produce O-Rings and other applications. It is highly resistant to fuels, chemicals, and high temperatures. Its main weakness is its susceptibility to very cold temperatures.
Like all other styles of o-rings, Viton o-rings are consistently employed as seals between two pieces of a machine or a system of tubes or pipes. O-rings are put in place during the assembly of a machine or system that has parts that need to be able to be taken apart for maintenance reasons. The o-ring, which has a variety of sizes, shapes and ridge styles, keeps these conjoined pieces from leaking the gas or liquid flowing through them. O-rings are made from many different materials, just one of which is Viton. Other synthetic rubbers include Teflon and silicone. Metal o-rings are also used in a number of industrial applications, specifically aluminum, copper, gold, silver and steel alloys. The sizes of Viton and other types of o-rings depend largely on what they are being used for. Industrial pipes require large o-rings, while the clear o-rings used for earring backings are quite small.

There are five main families of Viton, which can be distinguished by their composition. They are A, B, F, TBR and ETP. Family A, which consists of type A, AL, GAL and GLT-S, is used for general-purpose sealing, particularly in automobiles and aerospace applications. Family B, which consists of B, BL, GBL-S and GBLT-S, is used in chemical processing. Family F, including F, GF-S and GFLT-S, is used primarily for water and inorganic acids, while the TBR-S family is used for off-road applications with high pH requirements. The last family, ETP-S (Viton Extreme), is used in harsh environments such as oil exploration and production. A wide group of industries make use of o-rings, which has a simple design, is cost-effective and easily made but is also an incredibly precise tool. Even square tubing or machine parts have a particular type of o-ring specially designed for them called flat o-rings. Customized o-ring designs, often made from the versatile Viton material, are also available.
