A dispensing nozzle for dispensing anaerobic adhesives/sealants in an automated dispensing system, is provided. More specifically, the nozzle having a hollow body with an entry port and an exit port, the body having a wall with an internal wall surface which defines an elongate conduit arranged about a longitudinal axis of the nozzle, and linking the entry port to the exit port, where at the exit port the internal wall surface alternates in distance from the axis of the nozzle between axis proximate positions and axis distal positions, thereby forming a dispensing opening in the exit port of non-circular cross sectional area. The wall is flexible radially outwardly in the regions of the axis proximate positions.
