No more flats - To Go! Slime's new travel-size bottle is the perfect solution to flats on the go. Slime Tube Sealant seeks out and instantly seals punctures in your tubes up to 1/8" (3mm). The 4 oz size repairs one flat bicycle tire, whether you are stuck curbside, or out on the trail. When a puncture occurs, Slime's patented sealant is carried directly to the puncture. The pressure of the escaping air forces the particles into the opening, where they build up and intertwine to form a long-lasting, flexible plug. Instantly, air loss is blocked and a flat tire is prevented.
