Most Viton ® elastomers are categorized under the ASTM D1418 designation of FKM. This class of elastomer is further categorized by types. Type-1 FKM: is a copolymer of hexafluoropropylene (HFP) and vinylidene fluoride (VDF or VF2). A Type-1 Viton is generally 66% fluorine by content. Type-2 FKM: is a terpolymer of tetrafluoroethylene (TFE), vinylidene fluoride (VDF), and hexafluoropropylene (HFP). A Type-2 Viton is generally 68% fluorine by content.
Viton®o-rings can help you reduce costs by preventing seal failures, extending maintenance intervals, handling more aggressive fluids and higher temperatures, increasing safety and meeting stringent environmental regulations.
Viton® also offers mechanical ruggedness so seals and components resist damage during installation and use.
Viton® retains sealing force to prevent leaks even after compression for long periods in severe environments.
