More Information
Summary:A single piece valve extension support for vehicles with dualled tires and wheels using inflation valve extensions on the inner wheel. The valve extension support, made from a compressible elastomeric foam material, has an orifice through which the valve extension can pass. The valve extension support is inserted in the vent hole of the outer wheel, compressing the foam elastomeric material and generating an interference fit with the vent hole. The valve extension support is compressed around the valve extension passing through its' orifice. In this way, the valve extension support is able to dampen vibration that can lead to fatigue cracks in the inflation valve assembly, causing loss of air pressure in the inner dual tire and wheel assembly. Retention flanges on either side of the wheel prevent accidental removal of the valve extension support.
