Nutrak Tubeless Tyres Sealant Hi Fibre 250ml is a premium synthetic latex-based sealant designed for serious cyclists seeking reliable puncture protection across various terrains. Whether you're tackling Road, Gravel, or Mountain Bike trails, this sealant excels in both high- and low-pressure systems, ensuring your ride stays smooth and worry-free. Its advanced formula seals holes up to 7mm and coats sidewalls effectively, providing unmatched defense against unexpected punctures.
Ideal for Tubeless Ready and UST setups, this sealant incorporates extra puncture-sealing fibres that give riders the confidence to push boundaries—be it a downhill sprint or a challenging mountain climb. Easy to apply, it flows freely to fill every gap between bead and rim, even with rim inserts installed. With a lifespan of around 6 months under typical UK conditions, Nutrak’s sealant remains consistently effective without separating or forming lumps inside your tyre.
