Product Detail
Many industries use FFKM O-rings in critical applications where sealing failure is strictly prohibited. These industries include chemical processing, energy, semiconductors, pharmaceuticals, oil and gas recovery, aerospace, and other industries.
KALFLUO® 1680 has excellent resistance to chemical corrosion, organic acid, inorganic acid, alkali, ester, ether, ketone, aldehyde, superheated water and steam. The maximum operating temperature is 230 °C. It can be made into O-ring, diaphragm, gasket, rubber strip, rubber plate and customized products.
When purchasing FFKM O-rings, it is crucial to choose the appropriate size for your project. We offer various industry standard sizes of FFKM O-rings. Please contact us for more information on O-ring selection and customized solutions.
