Sealing Rings for the STAUFF Form EVO Tube Forming System ensure leak-free connections by using a large-volume elastomeric seal positioned between the tube surface and the fitting body's 24° conical bore. The standard sealing material, FKM (Viton®), supports use in high-temperature and aggressive media environments, while NBR (Buna-N®) allows operation down to -35°C. The unique sealing profile's large cross-section ensures secure, permanent sealing despite tube or fitting tolerances. The laterally equal profile of the sealing ring minimizes assembly errors on the formed tube end, and the system pressure enhances the sealing effect, making it ideal for high-pressure applications within the STAUFF Connect range of connecting parts, accessories, and spare parts.
