FINISHLINE FiberLink Tubeless Sealant is built with Kevlar® to deliver faster and stronger seals. Developed with proprietary FiberLink™ Technology, this pro latex formula sets a new standard for tubeless tire sealants. Kevlar® fibers work with fast-acting natural latex to seal punctures instantly, forming an adhesive bond reinforced by interlinking fibers. The result: maximum seal integrity, reduced air loss, and long-lasting performance.
