O-ring FFKM 75 Kalrez® 6375 - cross section 4,3 to 12 mm

The balck Kalrez® 6230 perfluoroelastomer O-Rings provide superior chemical resistance and low contamination from extractables in pharmaceutical and food handling applications where FDA and/or USP <87> and <88> Class VI @ 121°C, compliance is required. Kalrez® 6230 parts are especially suited for Water for Injection (WFI) systems, Steam-in-Place (SIP) cleaning and other critical systems. Kalrez° 6230 are thermally stable up to 260°C (500°F), permitting them to be used in Stage II Sterilization processes, where other elastomers lose their sealing ability.
