Finish Line FiberLink™ Inner Tube Sealant is built with Kevlar® to quickly repair existing punctures and prevent future flat tires.

Engineered with Finish Line's proprietary FiberLink™ Technology, our Inner Tube Sealant will repair 95% of bicycle tube punctures up to ¼“.

What is FiberLink™ Technology?

Kevlar® fibers flow rapidly to punctures, interlinking to create maximum strength mechanical seals, ideal for repairing bicycle inner tube punctures.

FiberLink™ Inner Tube Sealant is 100% latex-free, non-toxic, low odor, and cleans up easily with water.

FiberLink™ Inner Tube Sealant is available in 16oz, 32oz and 1 gallon sizes. 16oz and 32oz bottles include our patented Easy Application Cap to make installation through the valve stem both simple and mess-free. The extendable hose is compatible with both presta and shrader valve sizes, while the cap itself doubles as a shrader valve core removal tool.
