Metric O-Rings are employed in specialized applications and, like the name suggests, are standardized by metric dimensions. With a wide variety of sizes available, Metric O-Rings fill in the gaps left by the standardized AS568 o-ring chart. Metric O-Ring sizing is determined by the o-ring's inside diameter and cross section width. 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. For more information, please see: Comparison Properties Chart, PTFE Encapsulated O-rings, Material Shelf Life, and O-ring Groove Design Chart.
