The yellow sealant is excellent for sealing tubeless tyres and rims. The sealant is optimised for road (P Zero™), gravel (Cinturato™) and MTB (Scorpion™) applications. The P Zero™ SmartSeal variant is specially designed for sealing tyres with high air pressures. To ensure this, it contains ammonia and latex particles. The Cinturato™ and Scorpion variants, on the other hand, are ammonia and latex-free. Type CINTURATO™ AND SCORPION: The small unit with 125ml is ideally matched to the feel quantity for gravel and cross tyres, the 250ml unit is matched to the fill quantity for MTB tyres. Ammonia-free - protects the rim, reduces corrosion. Latex-free and protein-free to reduce the risk of allergic skin reactions. Leaves no sticky residue in the tyre. Compatible with a wide temperature range (-20 °C/68 °F to 70 °C/158 °F) Compatible with a wide air pressure range (1 to 7 bar / 15PSI to 100PSI) Compatible with an on-site CO2 emergency repair kit. (CO2 accelerates coagulation, so the sealant must be replaced afterwards.
