Sealing Rings for the STAUFF Form EVO Tube Forming System ensure a secure seal between the tube surface and the 24° conical bore of the fitting body. Made from FKM (Viton®), these rings are ideal for high-temperature and aggressive media applications. The large-volume elastomeric sealing and unique profile allow for reliable performance even with tube or fitting tolerances. The metal-elastomer combination enables use in temperatures down to -35°C, while the system pressure enhances the sealing effect, making it suitable for high-pressure hydraulic systems.
