Slime Tire Sealant is a safe, easy-to-use liquid formulated to prevent and repair flats in tires. Slime's Fibro-Seal technology combines a blend of environmentally friendly fibers, polymers, binders, and congealing agents with a viscous compound that stays liquid in all conditions. This combination uses the centrifugal force of the tire as it spins to cover the tread area of the tire and push into punctures, where the fibers, polymers, and congealing agents mix and clot to form a seal. This unique system fixes holes already in your tire and creates a layer of protection that takes care of new punctures as they happen. Tested and formulated to work in any pneumatic tire, Slime is designed to fix holes up to a 1/4 in a tire's tread area. Non-toxic, non-flammable, non-aerosol, and water soluble for easy cleaning. Fixes puncture holes up to 1/4 in tires Fibro-Seal technology Creates protective layer to fix new punctures as they happen Non-toxic liquid that cleans up with water Works in any tire
