ABSTRACT:
An adapter for use with a nozzle manifold of a hot runner injection molding system for fluidly connecting at least two runner sections and thereby distribute and conduct melt to cavities of an injection mold, includes a plug having at least one end face formed with a first opening for fluid connection to one runner section and a cylindrical or conical wall surface formed with a second opening for fluid connection to another runner section and extending at an angle with respect to the one end face, and a force-applying unit so acting upon the plug as to urge the end face and the wall surface into a fluid-tight pressure fit upon mating surfaces of the nozzle manifold.
