A collar for a hot runner nozzle of an injection molding apparatus includes a generally cylindrical body having a first flange extending inwardly from a first end thereof. The first flange is provided to abut a nozzle head and at least a portion of a nozzle body of a nozzle. An alignment flange projects from an inner wall of the generally cylindrical body and is spaced from the first flange. The alignment flange contacts the nozzle body to restrict tipping of the collar relative to the nozzle during assembly of the injection molding apparatus.
