An enteral dosing control coupling comprising a cylindrical collar defining a hollow internal chamber and a lumen extension tip projecting axially into the internal chamber, the lumen extension tip defining an internal lumen extending therethrough. In example forms, the lumen extension tip is integrally formed with the cylindrical collar. In other example forms, the lumen extension tip is a separate piece and is removably engageable within the cylindrical collar. In some example forms, the present invention relates to syringes, connectors, couplings, etc. having ISO 80369-3 formatted couplings. In other example forms, the present invention relates to connectors, couplings, etc. for adapting coupling formats other than the ISO 80369-3 coupling format to the ISO 80369-3 coupling format.
