Slime Tube Sealant is formulated & tested for use in all tube tires. Once installed, Slime remains liquid & will not harden or dry out. Slime is guaranteed for 2 years. As the Slime treated tube rotates, centrifugal force pushes the sealant to the tread area creating a layer of protection, repairing punctures as they occur & treating existing punctures. Slime is not intended for use in tubes losing pressure from sidewall punctures, bead leaks, damaged rims or faulty valves. Slime for tube type tires is NOT recommended for use in tubeless tires. Prevents & repairs punctures up to 1/8″ (3mm) using Fibro-Seal technology. Remains liquid inside the tire, coating the tread area as the tire rotates. Non-toxic, non-hazardous, non-flammable, non-aerosol & water soluble. Tubes treated with Slime can be patched with a conventional vulcanized patch using a bit of patience & care! What is Fibro-Seal Technology? Slime utilizes a state-of-the-art blend of environmentally friendly fibers, binders, polymers & proprietary congealing agents which intertwine & clot within the puncture. This Fibro-Seal lattice, together with the viscous transportation system (the green “goo”) seeks out & tightly packs itself into the puncture, preventing & repairing flats with a flexible long lasting plug. Note: Slime is not guaranteed to repair punctures caused by gashes from glass or metal or on punctures greater than 1/8″ (3mm).
