  • Patent number: 5472031
    Abstract: Flatproofing liquid is provided to tires through a one-way disposable valve assembly. In accordance with the method, the valve stem core is removed from the tire to allow the liquid to be freely admitted. A one-way valve is attached to the valve stem, and the tire is filled with the flatproofing material. The flatproofing material is then allowed to cure in the tire and in the valve. After curing, the valve is removed and discarded. The apparatus includes an inexpensive one-way valve for connection to the valve stem at one end and supply hoses at the other.
