The KF Centering Rings play a pivotal role in creating a resilient and efficient vacuum system, guaranteeing accurate alignment and effective sealing of KF flanges. KF centering rings are positioned between two flange faces and fastened with a surrounding flange clamp. An enclosed O-ring ensures the vacuum seal. We offer a range of sealing options, including Aluminum, Copper, EPDM, FFKM, Kalrez, Neoprene, Perbunan, Silicone, Teflon, and Viton, catering to diverse requirements for KF flanges.
Elastomer seals are permeable to gas and also emit gases. The gas permeability, or permeation, depends on the material, the type of gas and ambient conditions – mainly the temperature. After an adequate evacuation time, the outward gas stream decreases considerably, which means that a relatively constant permeation gas stream materializes.
Metal seals made of aluminum are suitable for assembly on high-grade steel flanges and can be used in a temperature range from –196 °C to 150 °C. They can only be used once. For assembly, special clamping elements for metal seals that generate significantly higher contact forces can be used.
Metal seals made of copper are suitable for assembly on high-grade steel flanges and can be used in a temperature range from –196 °C to 200 °C. A silver coating increases the maximum temperature to 450 °C. They can only be used once. They are suitable for a pressure range of 1 bar to 10–13mbar. For assembly, special clamping elements for metal seals that generate significantly higher contact forces must be used.
