The SLiME chemists have developed a state-of-the-art blend of environmentally friendly fibers, binders, polymers and proprietary congealing agents that intertwine and clot to seal punctures up to 1/4 (6mm) in tubeless tires and 1/8 (3mm) in tubed tires. This Fibro-Seal lattice, together with the viscous transportation system, seeks out and tightly packs itself into any puncture area, preventing and repairing flats with a flexible long-lasting plug. HOW DOES SLiME WORK? SLiME can be installed as a pretreatment before a puncture occurs. SLiME can be used to repair a flat tire or a slow leak. Simply remove the valve core from your tire, inject SLiME, reinflate it and rotate it. It s that easy! Once installed into the tire, SLiME remains liquid, evenly coating the inside. When a puncture occurs, the escaping air forces SLiME into the hole where it creates a long-lasting, flexible plug. It s non-flammable, non-toxic and water soluble. SLiME tube sealant prevents and repairs flats caused by puncturing objects up to 1/8 (3mm). SLiME works repeatedly, is non-flammable, non-toxic, cleans up with water and lasts for up to 2 years!
