Abstract: A nipple for spoked wheels of the tubeless type comprises a first and a second shoulder which are formed on a rod with a blind axial hole which is internally threaded at an end of the rod which is distal from the opening of the axial hole and in a zone of the rod which is proximal with respect to the opening, respectively. A first recess for a sealing ring is formed on the rod behind the first shoulder and at least a second recess for a second sealing ring is formed on the rod between the first recess and the second shoulder.
