Functional description

Under axial compressive load, ring type joints plastically deform and flow into the irregularities of the flange groove. Since the contact area of the ring type joint is relatively small, a very high compressive load results between the sealing surface of the ring type joint and the flange groove. This surface pressure is further increased especially by the RX and BX RTJ variants. Both variants are able to seal extremely high internal pressures. RTJ gaskets are produced from metal, so they remain in their compressed form, even when the surface pressure is relaxed. The sealing function of the RTJ gasket is reinforced by the axial forces acting on the sealing surfaces.
