A replacement aerosol nozzle assembly includes a coupler that is attachable around a neck of an aerosol container. A plunger is slidably attached to the coupler to engage a broken spray nozzle on the aerosol container when the coupler is attached to the neck of the aerosol container. A conduit is integrated into the plunger and the conduit fluidly engages the broken spray nozzle when the coupler is attached to the aerosol container. In this way the conduit is placed in fluid communication with an interior of the aerosol container. The plunger urges the broken spray nozzle downwardly when the plunger is depressed to spray contents of the aerosol container.
