Finish Line FiberLink Tubeless Sealant is built with Kevlar to deliver faster and stronger seals. This groundbreaking pro latex formula, powered by proprietary FiberLink Technology, seals punctures quickly, maximizes seal integrity, and delivers extended longevity.
Kevlar fibers work synergistically with fast-acting natural latex to seal punctures as they occur. Free-flowing latex cures rapidly to form an adhesive seal, reinforced by interlinking Kevlar fibers.
