Product Description
Ultimate Tubeless Sealant uses FiberFoam® technology to harness the power of carbon fiber to seal up to 7mm punctures without losing pressure. SILCA Ultimate Tubeless Sealant uses the power of a foaming latex formula combined with chopped carbon fibers to boost sealing power even at higher pressures. Starting with a clean, tubeless tire, use the 'pour in' method when installing on a tubeless rim. The quick sealing power makes it impossible to use a syringe or through the valve stem. When Silca says they can seal a +6mm, they mean it. The key is the carbon fiber that rushes to a puncture or open source and creates a fiber dam coagulant for a extremely effect seal. Every three months, it is recommend to use the Ultimate Tubeless Sealant Replenisher (sold separately). This maintenance can administered through the valve stem and refreshes the sealant.
