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 pro.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 is for cyclists who want reliable puncture protection and ease of use with their tubeless tires. The Silca Ultimate Tubeless Tyre Sealant V2 offers superior sealing power, lasting up to six months, and is easily injectable. Note that while this sealant is designed for ease of use, it's essential to understand proper application and maintenance for optimal performance.

FAQs
How long does the sealant last?
The Silca Ultimate Tubeless Tyre Sealant V2 lasts up to six months, depending on usage and environmental conditions.
How much sealant should I use?
Refer to the sealant bottle or tire manufacturer's recommendations for the correct amount of sealant for your tire size.
Can I use CO2 with this sealant?
Yes, the sealant is CO2 safe and will not coagulate during inflation.
How do I inject the sealant?
Remove the valve core using a valve core removal tool. Inject the sealant through the valve stem, then reinstall the valve core and inflate the tire.
What if the sealant doesn't seal a puncture?
Ensure the puncture is within the sealant's sealing capacity (up to 6mm). Rotate the tire to allow the sealant to reach the puncture. If it still doesn't seal, the puncture may be too large or the tire may be damaged. Check tire and rim compatibility.
Is this sealant safe for all tires?
The sealant is compatible with most tubeless tire systems. Always check your tire and rim manufacturer's recommendations.
How do I store the sealant?
Store the sealant in a cool, dry place away from direct sunlight.
Troubleshooting
Sealant not sealing the puncture.
Ensure you have the correct amount of sealant in the tire. Rotate the wheel to allow the sealant to reach the puncture. If the puncture is too large (over 6mm), the sealant may not be able to seal it. Check tire and rim compatibility.
Sealant drying out quickly.
Check for any leaks or punctures. Ensure the valve core is properly tightened. Top up the sealant regularly, especially if you ride frequently.
Difficulty injecting the sealant.
Make sure you are using the correct injector for your valve type. Ensure the sealant bottle is properly shaken. Clear any obstructions from the valve stem with a pin or tool if needed.

Setup, Compatibility & Care
Compatibility: This sealant is compatible with most tubeless tire systems. Ensure your tires and rims are tubeless-ready.
Initial Application: Follow your tire manufacturer's instructions for tubeless setup. Inject the recommended amount of sealant through the valve stem.
Regular Checks: Check your tires regularly for any air loss, especially after riding on rough surfaces. Top-up the sealant as needed.
Care: Store the sealant in a cool, dry place away from direct sunlight. Before each ride, inspect the tires for any signs of damage.
Injection Process: Ensure the valve is at the bottom of the wheel when injecting. Use a valve core removal tool to remove the valve core before injecting the sealant.
