Security Puncture Stop provides high protection against flat tyres that lasts several years. Security Puncture Stop is a water-based gel, which is filled into the tyre. It is most appropriate to fill it in the tyre as a preventive measure. But it can also be used as a puncture repair kit. The 250-ml bottle is suitable for smaller tyres, such as bicycle, handcart, wheelbarrow tyres. The liquid spare wheel is a set of a 1000-ml bottle and a small compressor and is used as a punture repair kit for car tyres (not as a preventive measure).
