Orange Seal Tire Sealant is proven to seal large punctures up to 1/4", performs under varying temperatures and altitudes, and is compatible with most bike tire systems. Orange Seal Cycling consists of multiple sizes and shapes of solid particles (nanites). When a puncture occurs, the nanites quickly seal the hole keeping the air in the tire and you rolling down the trail or road. Orange Seal consists of a proprietary premium latex. This latex formula was developed to co-exist with the "nanites" and clot the puncture at warp speed. The mixture has a long life span and is sustainable at extreme altitude and temperatures. It contains planet friendly biodegradable ingredients. 4oz of sealant adds only 119.6 grams to your wheel.
