Orange Seal Tubeless Tire Sealant 4 oz. / 118.3 ml NANITES: Orange Seal Cycling Tubeless Tire Sealant consists of multiple sizes and shapes of solid particles or what we call "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. PREMIUM LATEX: Orange Seal Cycling Tubeless Tire Sealant 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. The weight of a bike wheel has a major effect on bike performance. Orange Seal Cycling Tubeless Tire Sealant was developed to be as lightweight as possible. 4 oz of sealant adds only 1.2 grams to your wheel. ECO-FRIENDLY: Orange Seal Cycling Tubeless Tire Sealant contains planet friendly biodegradable ingredients. PROVEN: Orange Seal Cycling Tubeless Tire Sealant has been proven to seal a 1/4inch tire puncture.
