Silca spent over two years refining their Ultimate Tubeless Sealant formula to achieve industry-leading puncture protection while solving two key challenges:
Longevity - With our new blend of natural and synthetic latex. SILCA Ultimate Sealant Is a one-step process lasting +6 months and still, above all else, sealing punctures on race day.
Injectability - Now easily injected through the valve, eliminating messy installs.
By optimising carbon strand length and the blend of latexes, we ensured maximum sealing power without sacrificing performance in this V2 version of our tubeless tyre sealant.
Product Benefits
Sealing Power: The new Silca sealant seals holes up to 6+mm - 25% larger than conventional sealants --- for reliable performance in varied conditions.
Long-Lasting Formula: Combines natural and synthetic latexes for superior durability and sealing power. Hybrid latex extends durability up to 6+ months (environment-dependent).
Fiberfoam® Technology: Small strand carbon fibres create a strong “fibre dam” for faster sealing with minimal air loss. These fibres are 400% stiffer than fibreglass, ensuring quick, effective puncture protection. Seals punctures up to 7.5mm, 25% larger than standard sealants.
Cold-Weather Performance: Works in temperatures as low as -15°C for all-season reliability.
Easy Application: Injects through valve cores for mess-free installation. Pouring in during tyre installation is not mandatory.
CO Safe: 2 Does not coagulate or lose effectiveness when exposed to CO for short durations during tyre inflation.
Instructions
Preparation: Shake well before use.
Installation: Inject directly through valve cores with removable cores or pour into the tyre during installation.
Compatibility: Works with all tubeless-ready tyres and valve cores.
