ABSTRACT:
A tubeless tire valve has a valve body and an external annular gasket having an internal through hole. The gasket, when not mounted, has a diameter partially lower than the diameter of the cylindrical portion of the valve body, on which it will be inserted, and partially larger than the latter at the coupling area with the rim. Externally, the gasket has at one end an extended lip directed towards the rim, then an intermediate zone having a larger diameter than that of the hole in the rim, and close to the intermediate zone an annular groove of reduced diameter, while a hollowed impression is provided on the valve body at the zone where the rim will be positioned.
