Silca Ultimate Tubeless Sealant - V2 - Various Sizes

Season:2022

Brand:Silca

Code:SIAMAC039ASYWHT

Ultimate Sealant has been two-and-a-half years in the making and achieves market leading sealing performance, with longevity and easy maintenance. It's capable of sealing holes up to 6+mm, while its hybrid natural and synthetic latex formula makes it long lasting and injectable, allowing clean top-up.

Silca's sealant has long made use of Fiberfoam® technology, which contains small strand carbon fibres, 400% stiffer than fibreglass, to plug punctures quickly and with minimal air loss.

The new formula ensures it will dry less rapidly and stay liquid for up to 6+ months, while adjustments to the carbon strand length have facilitated injectability, without any sacrifice of sealing power. The formula is also safe with CO2, not losing its effectiveness or coagulating during the inflation process.

The fibre dam created by the carbon fibre gives fast, effective sealing with minimal air loss, even in extreme conditions, such as temperatures down to -15°C, ensuring this sealant won't let you down.

Shop mechanics, meanwhile, will benefit from reduced labour time for installation and enhanced customer satisfaction, due to the sealant's ability to be injected through the valve core for easy replenishment.

Finally, Ultimate sealant is not only non-toxic and more environmentally friendly than competitors, but kind to your tyres, as it contains none of the ammonia that can break them down over time.


  • Unbeatable sealing power in an injectable, long-lasting formula
  • Fibrefoam® technology forms interlocking “fibre dam” to seal holes up to 6+ mm
  • This is 25% larger than standard sealants
  • Hybrid Latex formula stays liquid for up to 6+ months
  • Natural and synthetic latex blend is durable, fast sealing and non-toxic
  • Injectable via valve for mess-free installation
  • Effective down to -15°C, for year-round reliability
  • Will not coagulate when exposed to CO2 during short term tyre inflation
  • Ammonia free
  • Contains latex, avoid inhalation and wear protective gloves/eye wear during application
