Viton O-Rings
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.

Applications of Viton O-Rings
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 with parts that need 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-Ring Design and Customization
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.
Types of Viton
There are five main families of Viton, which can be distinguished by their composition. They are A, B, F, TBR, and ETP.
- Family A
- Consists of type A, AL, GAL and GLT-S and is used for general-purpose sealing, particularly in automobiles and aerospace applications.
- Family B
- Consists of B, BL, GBL-S and GBLT-S and is used in chemical processing.
- Family F
- Consists of F, GF-S, and GFLT-S and is used primarily for water and inorganic acids.
- Family TBR-S
- Used for off-road applications with high pH requirements.
- Family ETP-S (Viton Extreme)
- Used in harsh environments, such as oil exploration and production.
Benefits of Using O-Rings
A wide group of industries make use of o-rings, which have a simple design, are cost-effective and easily made but are also incredibly precise tools. 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.
