The Replacement Elastomeric O-Rings serve as crucial sealing components for KF flanges when used with centering rings, requiring replacement after extended use. These O-rings are designed to fit around both Aluminum and Stainless Steel centering rings and adhere to International Standards Organization specifications. Kalrez 6375, belonging to the Perfluoroelastomer (FFKM) family, is renowned for its carbon black-filled compound and exceptional sealing performance, especially in temperature cycling applications. With outstanding resistance to harsh chemicals and high temperatures up to 326°C, it is widely preferred for diverse applications due to its broad compatibility and reliability.
