An inflation device includes a central tube, a first mounting unit mounted onto an outside of a reception end of the central tube and a second unit connected to a connection portion on the other end of the central tube. The first mounting unit includes a first casing and an end cap, and the reception end includes a valve mouth and a core tube received therein. The second mounting unit includes inner threads that are connected with the connection portion. A groove is defined in the second mounting unit and an O-ring is engaged with the groove. The first and second mounting units can be connected with an American style tire valve and a French style tire valve, respectively. The first and second mounting units each have outer threads with the same diameter so as to be connected with a tire pump. |
