WTB TCS Tubeless Tire Sealant is a proprietary, ammonia-free synthetic latex sealant that won't corrode your rims. It's the best option for fast and reliable puncture repair up to 6mm. We recommend thoroughly mixing the sediment at the bottom of the bottle before applying the sealant.  The sealant performs best at common riding temperatures down to 15°F (-9.4°C) because the more anti-freeze chemicals are added, the more the sealant performance is reduced. TCS Tubeless Tire Sealant uses a tackifying process to seal punctures rather than relying on the evaporative effects of many ammonia-based formulas. As a result, the sealant performs better in wet conditions where other sealants have trouble clotting due to reduced evaporation. Synthetic latex keeps the sealant fresh for many months of riding.  

TCS Tubeless Tire Sealant is a reliable, thoroughly tested sealant that completes the patented WTB TCS system for tubeless tires, rims, wheels, valves, tape and sealant. TCS (Tubeless Compatible System) is a standardized tubeless rim/tire system designed to meet ETRTO international standards and provide unparalleled reliability.
