Filter Seals High Temprature O Rings FKM 30 - 90 Shore Hardness ROHS W270
Standard O-Rings are available in 369 sizes as set up by the Aerospace Standard 568 published by the Society of Automotive Engineers. These sizes are designated by dash numbers shown on the 568 DASH Chart and are standardized by imperial dimensions. Standard O-Rings are specified by their inside diameter and cross section width. AS568 is the most commonly used standard in the U.S. for aerospace, automotive and general industrial applications. For more information, please see: Aerospace Standard 568 Dash Number, Comparison Properties Chart, Teflon® Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. FKM® is also known as: Fluorocarbon and FKM. FKM® 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.
