Silca Ultimate Tubeless Tyre Sealant is long-lasting, fast-sealing and CO₂ safe.

The Silca Ultimate Tubeless Tyre Sealant (1L) is engineered for market-leading puncture protection, longevity, and easy maintenance. Developed over two-and-a-half years, this high-performance tubeless sealant offers superior sealing power, lasting durability, and hassle-free injectability, perfect for road, gravel, and mountain bike riders.

  • Unmatched Sealing Performance – Seals holes up to 6+mm, 25% larger than standard sealants, for exceptional flat protection.
  • Advanced Fiberfoam® Technology – Small strand carbon fibres (400% stiffer than fiberglass) create an interlocking “fibre dam” to quickly seal punctures with minimal air loss.
  • Long-Lasting & CO₂ Compatible – Hybrid natural and synthetic latex formula remains liquid for up to 6+ months, resists coagulation with CO₂, and works in temperatures as low as -15°C.
  • Mess-Free, Easy Installation – Injectable via the valve core, reducing maintenance time for bike shops and home mechanics.
  • Eco-Friendly & Tyre Safe – Ammonia-free, non-toxic, and designed to protect your tyres from degradation over time.

Perfect for Every Ride

Whether you're tackling gravel adventures, road racing, or MTB trails, the Silca Ultimate Tubeless Sealant delivers unbeatable puncture protection for year-round reliability.
