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.

This elastomer possesses mechanical properties similar to Viton®, with the exception of its slightly lower compression set resistance. It is more suitable for sensitive applications where lighter compressive forces are applied to energize the seal. This core has a Shore A hardness of 70 but it also offers a broader operating temperature range of -80°F to +500°F. (-62°C to +260°C). For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart.
