ABSTRACT:
A flexible extension air hose particularly for use with dual wheel tires on trucks or recreation vehicles. The hose contains a slidable central cable that extends to a nozzle that screws to the tire valve stem and contacts the valve. The other end of the hose is fitted with an coupling that may be manually adjusted to compensate for variations in the length of the central cable that is caused by bending in the hose. Thus, a air service nozzle pressed to the coupling causes the cable to depress the tire valve so that air may be added or the tire deflated from some convenient position.
