FI-FD STAUFF Form EVO Sealing Ring

The sealing of the only possible leakage path is provided primarily by the large-volume elastomeric sealing of the STAUFF Form EVO Sealing Ring which is specifically positioned between the surface of the tube and the 24° conical bore of the fitting body during assembly. FKM (Viton®) is used as the standard sealing material and enables problem-free use of the STAUFF Form EVO tube forming system for challenging applications involving high temperatures or aggressive media. Thanks to the combined metal-elastomer sealing, the usage of the systeme in low-temperature ranges down to -35° C is possible without restriction – as is also the case with NBR (Buna-N®). The unique sealing profile has a particularly large cross-section in order to sealsecurely and permanently, even in the event of unfavourable tolerances of the tube or the tube fitting. Possible errors during assembly on the formed tube end are consistently avoided by the laterally equal profile of the sealing ring. The sealing effect is supported by the system pressure of the hydraulic system, so that the STAUFF Form EVO tube forming system is perfectly suited for high-pressure applications.
