ABSTRACT:
A plug and tool are provided for repairing and sealing a puncture of a tire. The plug is generally cylindrical in shape and is made from a rubber-like material which is stiffer and more durable than prior repair plugs. The plug has a cylindrical shank portion and adjoining circular head portion. Extending around the outer edge of the head portion is a thin auxiliary sealing ring. On the periphery of the shank portion is a plurality of closely spaced sealing rings with grooves therebetween. When the shank portion is forcibly inserted into a puncture, the sealing rings provide multiple sealing members by individually radially compressing and locally conforming to the size and shape of the puncture. Additional sealing is provided by bonding the head portion to the inner surface of the tire. At the end portion of the plug opposite to the head portion is a metal loop. There is provided a tool having a handle portion and adjoining slender shank portion for forcibly inserting the plug into a puncture. The free end of the shank portion has a hook shape which engages the metal loop for pulling the plug into the puncture.
