SILCA Ultimate Tubeless Tire Sealant, 1L Bike Sealant Proactively Seals Punctures Up to 7.5 mm, Injectable Through Valve & Stays Liquid 6+ Months in All Weather Conditions

FAST & EFFECTIVE: Quickly fills punctures up to 7.5 mm - 25% more coverage than conventional bicycle tire sealants. Works with all tubeless tires & valve cores. Proactively seals punctures by filling holes as they occur. FIBERFOAM TECHNOLOGY: Small strand carbon fibers create a strong 'fiber dam' for faster sealing with minimal air loss. These fibers are 400% stiffer than fiberglass, ensuring effective protection. EASY TO APPLY: Silca's tubeless bike tire sealant easily injects through the valve cores for mess-free install even with tires mounted (injector sold separately), or you can pour directly in the tire during install. HIGH PERFORMANCE: This mountain, gravel, and road bike tire sealant is CO2 safe & works in temps as low as 10 degrees F / -15 degrees C for all-season reliability. LONG-LASTING: The hybrid latex used in this tire foam fill stays liquid for 6+ months (weather dependent), to reduce frequency of sealant top-offs and replacement.
