Description

Unmatched Sealing Power, Now Injectable!

SILCA Ultimate Sealant (500ml) combines injectable Fiberfoam® technology with a hybrid natural and synthetic latex formula to deliver the highest level of longevity available along with unbeatable puncture sealing capabilities for tubeless tires. And now it's designed to be easily injected through valves with removable cores, eliminating the potential for mess.

SILCA Ultimate seals holes up to 7.5+mm, 25% larger than conventional sealants. Recycled carbon fibers form an interlocking "fiber dam" for increased surface area for faster sealing with minimal air loss. These fibers are 400% stiffer than fiberglass, ensuring punctures are sealed quickly and effectively.

The hybrid latex formula increases durability, extending performance life to up to 6+ months (depending on environmental conditions). It's also Winter-ready, effective even in the cold.

Features:

  • Hybrid Latex Formula: Combines natural and synthetic latexes for superior durability and sealing power.
  • Fiberfoam® Technology: Carbon fibers form a robust, interlocking "fiber dam" to seal punctures up to 7.5mm, 25% larger than standard sealants.
  • Cold-Weather Performance: Effective down to 10°F / -15°C, ensuring year-round reliability.
  • Now Injectable: Clean, efficient application via the tire valve—not mandatory to pour in during tire installation.
  • Longevity: Lasts 6+ months, minimizing maintenance.
  • CO2 Safe: Does not coagulate or lose effectiveness when exposed to CO2 during tire inflation.
  • Injector Sold Separately.
  • 500ml bottle

The Best Tire Sealent

Does a fantastic job of sealing tubeless road bike tires. No leaks from minor cuts in tire. Also helps with normal time leakage of air when bikes sits for 3-4 days
