Z-Sealant was designed for preventing punctures on tube or tubeless tyre systems. For use with an inner-tube it needs to be injected into the valve using the nozzle provided or into the side of the tyre for a tubeless system, helping to prevent punctures up to 3mm. The latex-based-formulation remains effective for a minimum of 6 months. In case of hot weather, use more regularly. The Z-Sealant formula contains less than 1% ammonia and won't damage your tyres, nor will it freeze. Capacity : 125ml (min 50ml per tyre)
