Muc-Off Tubeless Sealant 500ml

Designed for road and gravel use, this high-performance tubeless sealant seals punctures quickly to keep you riding. It seals holes up to 7mm and uses a combination of advanced synthetic latex and biodegradable sealing particles to form a reliable seal against leaks. The formula can be applied through a Presta valve or added directly into the tyre, and it bonds to the inside tyre wall with advanced polymer technology. The sealant is water-based, non-toxic, and biodegradable, with microfibres and mineral flakes helping to fill larger tears. It stays effective for several months, typically 3–6 months, and is compatible with CO2 inflation for mid-ride repairs. It remains usable across a wide temperature range and will not freeze below -15°C. The product is designed for tubeless-ready and UST wheels and tyres and is suitable for use across downhill, enduro, and road riding. A UV-detectable dye is included to help spot hidden punctures after a ride.
