Silca Ultimate Tubeless Sealant V2 - 65ml

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.
