RTJ-Gaskets with Raised Sealing Surface (Soft Iron, Octagonal)

The octagonal design can also be used in flange connections with RTJ-groove [flank angles 23°] according to the above mentioned norm. Different to the oval form, an extensive stress is created right from the start on the contact surface gasket/flange. The sealing surface size is therefore independent from the assembly force; the octagonal type is the the preferred design.
