Silca Ultimate Tubeless Sealant w/ Fiber Foam (16oz)
Silca Ultimate Tubeless Tire Sealant:
Silca Ultimate Tubeless Sealant uses the power of a foaming latex formula combined with chopped carbon fibers to boost sealing power even under high pressures. A unique foaming latex formula is combined with 5% by volume chopped carbon fibers that get evenly dispersed within the sealant while riding, which allows for a higher fiber content than possible with Kevlar or fiberglass. At this high fiber loading, bundles of carbon fiber are carried directly to the puncture by the sealant flow and deposit the carbon fibers over the hole forming a dam of fibers against the tire casing. This dam of high stiffness/high strength fibers has been shown to seal holes in testing up to 7.5mm, some 25% larger than conventional technologies.
Note: Use in combination with Silica Ultimate Sealant Replenisher every 90-120 days to prolong sealant life.
Features:
- Seals up to 7.5mm holes
- Must be poured into tire during install as it seals holes larger than your valve
- 6, 9, and 12mm recycled carbon fibers are dispersed evenly in a foaming latex to create an ultra strong seal
- CO2 can be used to seat tires but should be removed as soon as possible and replaced with air to preserve life of sealant
- Effective down to 10F/ -12C
- Made in the USA

Silca Ultimate Tubeless Sealant w/ Fiber Foam (16oz)
This is completely useless. Got a 1-2 mm puncture and this would not seal it. Switched to Orange Seal and it sealed it within seconds.
According to Silca, they messed up the first few bottles and sent out 20% carbon fiber instead of 5%. I asked for a refund but they sent me a new bottle. Not sure if I want to use it. Am stuck with this and the 32 Oz of the Replenisher. $60 wasted. I might use the new silca bottle in front tire and use orange in the rear. I wish I could get a refund instead.
It did slow the leak, but also spread all over my bike, pealed off the paint on my Zipp tubeless rim tape. They said in some cases it delaminates the rim tape. Do not buy!!!
