No more flats! Slime's Prevent and Repair Tyre Sealant seeks out and instantly seals tread area punctures in tubeless Tyres up to 6mm. When a puncture occurs, our patented sealant is carried directly to the source. 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 Tyre is prevented. Install in any of your tubeless non-highway vehicles (including ATVs/UTVs, golf carts, riding lawn mowers, small trailers, tractors, scooters and much more) and enjoy two years of continuous flat Tyre protection.
