FKM centering rings are used as sealing elements between flanges in the ISO-KF system. FKM fluoroelastomer (Viton®) is a material with exceptional chemical and temperature resistance, providing a reliable seal even in high vacuum and temperatures up to 200 °C. These rings are compatible with all standard KF clamps and flanges, making them an ideal solution for applications in vacuum pumps, analytical instruments and process engineering.
