Japanese Industrial Standard O-Rings are another popular classification system used around the globe. Published by the Japanese Standard Association, these o-rings are also categorized using the metric system. JIS O-Rings are used in many different fields, but typically are implemented in Japan's semiconductor, automotive and machine tool industries. Viton® is also known as: Fluorocarbon and FKM. Viton® is a registered trademarks of DuPont® Dow Elastomers.

A fluoroelastomer compound with a combination of exceptional mechanical properties and compression set resistance. This particular energizer gives an O-ring excellent memory and the ability to recover rapidly from deformation. This core has a Shore A hardness of 75 with a suggested operating temperature range of -10°F to +300°F (-23°C to +150°C) in encapsulated applications.
