The Slime Inner Tube Sealant 237ml is an excellent choice for preventing and repairing punctures. It stays liquid inside the tire, coating the tread area as you ride, ensuring continuous protection. Plus, it's non-toxic, non-hazardous, non-flammable, and water-soluble, making it safe and easy to use. Slime Tube Sealant is formulated and tested for use in all tube tires. Once installed, Slime remains liquid and 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. 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. What is Fibro-Seal Technology? Slime utilizes a state-of-the-art blend of environmentally friendly fibers, binders, polymers and proprietary congealing agents which intertwine and clot within the puncture. This Fibro-Seal lattice, together with the viscous transportation system (the ""green"" goo) seeks out and tightly packs itself into the puncture, preventing and repairing flats with a flexible long lasting plug. Slime Tube Sealant seeks out and instantly seals tread area punctures up to 1/8" (3mm) using Fibro-Seal technology. Install in your bicycles, dirt bikes, wheelbarrows, riding mowers and more, and enjoy two years of continuous flat tyre protection. This inner tube formulation should not be used in a tubeless setup. Slime sealants are designed to treat tread area punctures only and should not be used to repair sidewall punctures, snake bites, rim spoke punctures or gashes from metal or glass.
