An axially movable tubular connector assembly component of a charging machine for a reactor adapted to be located on and movable over a platform of the reactor into alignment with, and for connection to, the ends of individual stand pipes for the purpose of exchanging fuel or moderator components which are introduced into the core of the reactor through the stand pipes. The connector assembly includes a cylinder, an annular piston slidable into and out of one end of the cylinder and a cylindric open-ended bellows unit located within and secured at one end to the piston crown. Pressurized fluid admitted into an annular chamber formed within the cylinder between the bellows unit and the surrounding piston and cylinder wall serves to extend the bellows unit and advance the piston so as to seat the annular crown onto the end of the stand pipe thereby to establish a charging passageway for the stand pipe leading through the open-ended bellows unit and the other end of the cylinder into the interior of the charging machine. The piston can be unseated by depressurizing the annular chamber and applying a driving force to the piston in the opposite direction.
