AS568 Perfluoroelastomer O-Rings
Standard O-Rings (AS568)
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 nFor more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart. Perfluoroelastomer is also known as FKKM and Perfloro.
Parts resist over 1,800 different chemicals, while offering the high temperature stability of PTFE (327°C). They’re used in aggressive chemical processing, pharmaceutical, oil rcovery, gas recovery, and aerospace applications. The proven, long-term performance of Kalrez® parts can mean less repairs, seal changes, inspections and equipment uptime for greater productivity and yield.
