1. A process connection, wherein the process connection comprises:
an external threaded adapter that has a screw-in passage and that is provided with an internal thread;
an internal threaded adapter having a cylindrical through passage and an external thread; and
an annular molded seal,
wherein the external threaded adapter has a radially peripheral inwardly projecting hollow cylindrical projection at one end of the screw-in passage,
wherein the annular molded seal contacts said hollow cylindrical projection in the axial and radial direction within the screw-in passage of the external threaded adapter,
wherein the external thread of the internal threaded adapter is in screw engagement with the internal thread of the external threaded adapter,
wherein the internal threaded adapter is configured to press the molded seal axially onto the hollow cylindrical projection of the external threaded adapter,
wherein the process connection has a thrust washer that is provided between the internal threaded adapter and the molded seal
wherein the process connection has a spacer ring that radially surrounds the molded seal in the interior of the external threaded adapter and rests on the hollow cylindrical projection,
and wherein the spacer ring is configured to limit a radial deformation of the molded seal during the pressing by the internal threaded adapter and/or the degree of the maximum axial pressing of the molded seal by the internal threaded adapter and wherein the spacer ring is formed in one piece with the thrust washer.
