ABSTRACT:
Pump connector for Presta valve is disclosed in which one end of a pump connector valve seal is formed with a hollow chamber, and is disposed inside a space of a cap having a channel. The hollow chamber is assembled with a valve seal insert which includes a through hole. The second end of the through hole is formed with an inner edge corresponding to the shape of the shoulder section of the Presta valve. An end cap is assembled with the cap for preventing the pump connector valve seal from separating from the cap. Accordingly, the Presta valve can be screwed together with a first internal thread of the cap, and at the same time the shoulder section of the Presta valve is tightly fitted to the inner edge of the valve seal insert for direct inflation.
