SILCA Ultimate Tubeless Sealant 500 ML

Injectable through your valve, seals 6mm+ punctures, and lasts up to 6 months. The perfect sealant for riders seeking ultimate sealing power, longevity, and ease of use.

SILCA's new Ultimate Sealant addresses the two biggest complaints from the original formula — it dried out too quickly and the longer carbon fiber strands made valve injection messy and difficult. The new blend of natural and synthetic latex is a one-step process that stays liquid for 6+ months while still delivering race-day puncture sealing performance.

Please Note: Injectors are sold separately. Not compatible with Reserve valves.
