Injectable through your valve, seals a 6mm+ puncture, and lasts up to 6 months. The perfect sealant for those looking for the ultimate sealing power, longevity, and ease of use. The original sealant formulation, released 2.5 years ago, was designed primarily for effective puncture sealing by maximizing the surface area of the liquid latex for enhanced performance. Pro racers valued its convenience, as they frequently changed tyres based on race conditions and could easily pour in fresh sealant without needing to inject it through the valve. However, we heard two main concerns from more casual cyclists - it dried out quickly when not in use, and its composition of the longer strand carbon fibre made injection difficult and problematic. Silca Ultimate Tubeless Sealant V2 has been developed over two-and-a-half years to deliver market-leading sealing performance with exceptional longevity and easy maintenance. Capable of sealing holes up to 6mm, its hybrid natural and synthetic latex formula provides a long-lasting, injectable solution for clean and efficient top-ups. Silca's sealant utilises Fiberfoam technology, incorporating small carbon fibre strands that are 400% stiffer than fibreglass. This enables punctures to be plugged rapidly with minimal air loss. The latest formula remains liquid for up to six months, drying more slowly while maintaining its superior sealing power. Adjustments to the carbon strand length have improved injectability without compromising performance. The formula is also CO2 safe, ensuring it stays effective and does not coagulate during inflation. The carbon fibre-reinforced seal forms a strong, airtight barrier, performing reliably even in extreme temperatures as low as -15°C.
This guide helps cyclists use the Silca Ultimate Tubeless Tyre Sealant V2 to effectively seal punctures and maintain tire pressure. Designed for riders seeking superior sealing power and longevity, this sealant offers a long-lasting, injectable solution for tubeless tires. A key benefit is the ability to seal punctures up to 6mm, while a potential drawback is the need for periodic top-ups to maintain optimal performance.

How do I store the sealant?
Store it in a cool, dry place away from direct sunlight.
What is the shelf life of the sealant?
The sealant should remain effective for up to six months after installation, depending on usage and environmental conditions.
Can I use this sealant in extreme temperatures?
Yes, it performs reliably in temperatures as low as -15°C.
How do I clean up the sealant if I spill it?
Use water and a cloth. The sealant is water-soluble when wet.
Troubleshooting
Sealant leaking from the tire after injection.
Rotate the tire to distribute sealant and allow time for the sealant to fully seal the puncture. Re-inflate the tire to the recommended pressure.
Sealant clogging the valve.
Remove the valve core and flush with water. Alternatively, replace the valve core.
Tire pressure dropping despite sealant.
Check for larger punctures or sidewall cuts. Add more sealant, and if the issue persists, the tire may need replacement.

Setup, Compatibility & Care
Compatibility: This sealant is compatible with most tubeless tire systems. Always check the tire manufacturer's recommendations.
Injection: Before injecting, ensure the valve core is removed using a valve core removal tool. Shake the sealant bottle well.
Injection: Inject the sealant through the valve stem.
Rotation: Rotate the tire to distribute the sealant evenly.
Inflation: Inflate the tire to the recommended pressure.
Inspection: Check for any leaks and add more sealant if necessary.
Care: Store the sealant in a cool, dry place. Replace the sealant every six months or as needed.
