A sealing system and sealing composition are provided for inflatable articles containing air under pressure. The sealing composition includes particles or particulates of three-dimensional shapes having sharp corners thereon which tend to dig into the article around the opening and wedge themselves therein. The sealing composition also includes fibers, at least some of which are fibrillated. The fibers tend to wrap around the particles and further plug the leak opening. The particles and the fibers are in a liquid carrier which also tends to form a bond of the particles and fibers in the leak opening. The particles in the composition have dimensions covering a particular range of sizes for different articles, the larger dimension being useful in larger dimension articles, such as large tires for construction machines, and the smaller dimension being useful in smaller articles such as footballs and basketballs, for example.

[ Having described the invention, what is claimed is:] [1.] A single sealing composition for sealing multiple size leak openings in a variety of inflatable articles containing air under pressure, said composition comprising a multiplicity of three-dimensional particles including at least four faces

[ Having described the invention, what is claimed is:] [1.] A single sealing composition for sealing multiple size leak openings in a variety of inflatable articles containing air under pressure, said composition comprising a multiplicity of three-dimensional particles including at least four faces and each having shapes including width, height and thickness dimensions, each dimension being different from each other dimension, with a plurality of sharp corners thereon, a multiplicity of fibers, and a liquid carrier, said particles being in sufficient number so that at least one of the dimensions of several of the particles is sufficient to block one of the multiple size leak openings, said fibers being wrapped on the particles in the leak opening, and said liquid forming a binder to bind the particles and fibers at the opening.
