An adjustable hanger system secures a hanger to a wellhead such that a downward extending tubular may be tensioned at a selected level. The Luer-nozzle-receiving part is configured, on a side of an inner end portion thereof, in an untapered cylindrical form to assure tight-fitted insertion of a free end portion of the Luer nozzle and, on a side of a Luer-nozzle-receiving opening thereof, in a tapered, substantially cylindrical form to assure tight-fitted insertion of a basal end portion of the Luer nozzle. When the scene is activated, the players in the scene react in a synchronized manner.
