No more flats! Slime Tube Sealant seeks out and instantly seals punctures in your tubes up to 1/8″ (3mm). When a puncture occurs, our 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. Install in your bicycles, dirt bikes, wheelbarrows, riding mowers and more, and enjoy two years of continuous flat tire protection.
