WTB went through five different formula revisions to create the TCS Tubeless Tire Sealant, which quickly and reliably repairs punctures. The unique composition seals the sealant particles directly at the puncture site, creating a flexible, long-lasting repair. Key Features Instantly seals punctures up to 6 mm in size Ammonia-free formula stays fresh for several months after application Optimized for temperatures down to -9.4 °C Made from synthetic latex – no risk of natural latex allergy Water-based, light green in color Designed for ideal compatibility with WTB tires, but also compatible with other tubeless tires Includes a cap with an injector for easy filling through the valve Video
