Finish Line Tubeless Tire Sealant is a revolution in tubeless technology. Since there is no liquid latex or ammonia in Finish Line sealant, it is naturally non-toxic, hypoallergenic and safe for carbon fiber rims. Additionally, Finish Line Tubeless Tire Sealant cleans up easily with water – no more scrubbing or scraping cured latex from tires and rims. FiberLink technology makes this possible. Utilizing DuPont Kevlar fibers, FiberLink seals are extremely robust once they plug a hole. When a puncture happens, fibers rush into the wound and quickly stop air loss. As the tire flexes while it is ridden, the FiberLink mesh tightens and reinforces itself, creating a confidence-inspiring seal that will last ride-after-ride.
