Slime's product range is the world’s safest and most effective sealant. When a puncture occurs, the patented sealant is carried directly to the puncture. The pressure of the escaping air forces the Fibro-Seal® 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 tyre is prevented. Prevents and repairs flat tyres Lightweight, non-corrosive, non-hazardous Seals bead Tyre sensor safe
