Description

Unmatched Sealing Power, Now Injectable!

SILCA Ultimate Sealant (1L) combines injectable Fiberfoam® technology with a hybrid natural and synthetic latex formula to deliver the highest level of longevity available along with unbeatable puncture sealing capabilities for tubeless tires. And now it's designed to be easily injected through valves with removable cores, eliminating the potential for mess.

SILCA Ultimate seals holes up to 7.5+mm, 25% larger than conventional sealants. Recycled carbon fibers form an interlocking "fiber dam" for increased surface area for faster sealing with minimal air loss. These fibers are 400% stiffer than fiberglass, ensuring punctures are sealed quickly and effectively.

The hybrid latex formula increases durability, extending performance life to up to 6+ months (depending on environmental conditions). It's also Winter-ready, effective even in the cold.

Features:

  • Hybrid Latex Formula: Combines natural and synthetic latexes for superior durability and sealing power.
  • Fiberfoam® Technology: Carbon fibers form a robust, interlocking "fiber dam" to seal punctures up to 7.5mm, 25% larger than standard sealants.
  • Cold-Weather Performance: Effective down to 10°F / -15°C, ensuring year-round reliability.
  • Now Injectable: Clean, efficient application via the tire valve—not mandatory to pour in during tire installation.
  • Longevity: Lasts 6+ months, minimizing maintenance.
  • CO2 Safe: Does not coagulate or lose effectiveness when exposed to CO2 during tire inflation.
  • 1,000ml bottle

Much easier to work with.

I'm using Reserve Fillmore valves so I wasn't able to inject this stuff but I still used a sealant injector to get it into the tire without making a mess and it did not clog. I've already had a small puncture that sealed but it did take a while, it was close to the sidewall and I probably didn't have enough sealant in the tire to be honest. I didn't look at the recommended amount for the size tires I'm using so I should have added 15-20ml more. Assuming this stuff lasts at least a few months and the fiber foam stays suspended in the sealant rather than gathering along the tire bead making it less effective then I will buy it again. It is expensive but so far so good and it is a vast improvement over the original stuff as far as usability goes.

So far so good

Sealed very good. Able to use injector through stem although it's hard to push through. Seems like a better option than their original 2 part stuff.
