Vittoria Tyre Sealant - 500ml Vittoria introduces a novel solvent-free tyre sealant formula, specifically tailored for TNT tyres, yet seamlessly compatible with standard UST, serving as an effective flat prevention measure. The cornerstone of Vittoria's Universal Tubeless Tyre Sealant lies in its liquid base, engineered to be sufficiently thin to swiftly and efficiently locate and seal even the minutest punctures. Suspended within this base are platelets, which aggregate to seal larger punctures, ensuring protection against punctures of any size and on any type of bicycle. In rigorous testing, Vittoria's new sealant demonstrated the ability to instantly seal punctures of up to 7mm and maintained excellent air retention for distances of up to 1200km. Moreover, the ammonia-free formula safeguards against tyre damage, rendering it compatible with tyre inserts such as Air-Liner and Vittoria's cotton compound tyres.
