Tunap Tubeless Sealant 250ml

TUNAP SPORTS Tubeless Sealant 250 ml is a sealant for fitting and permanent use in tubeless bicycle tyres. The sealant is suitable for cyclists who want puncture protection on road, MTB and gravel tyres, and can quickly seal holes of up to 7 mm thanks to Kevlar fibres. The ammonia-free, water-based sealant is suitable for all tubeless rims and can also be used preventively in tyres with an inner tube.

A tubeless setup only works properly when the tyre, rim and sealant seal reliably together. This sealant helps close gaps between the rim and tyre bead and remains active in the tyre for 6 to 12 months. This makes it suitable for anyone who wants to fit, maintain and protect their tyres properly against small leaks while riding.
