ABSTRACT:
In a centered double joint, a centering device interconnects a first single joint to a second single joint. The centering device includes a pin extending axially outwardly from one of the single joints. An intermediate element is fitted onto and laterally encircles the pin with its radially outer surface fitted into the interior of a journal extending axially outwardly from the other single joint. A gasket laterally encircles an axially extending portion of the pin and of the journal and is in sealed engagement with each of them. A shaped reinforcing ring is tightly attached to the end of the gasket secured to the pin and seats against the adjacent end face of the intermediate element.
