Slime's Emergency Flat Tyre Repair offers the safest and most effective sealants in the world. Upon a puncture, the patented sealant is transported directly to the site. The escaping air pressure pushes the Fibro-Seal particles into the puncture, where they accumulate and interlock to create a durable, flexible plug. This immediately stops air loss and prevents a flat tyre. Slime Tyre Sealant seeks out and instantly seals tread area punctures up to 1/4" (6mm) using Fibro-Seal Technology. Use Slime Tyre Sealant with an air source for emergency repair of tyre punctures on small/medium wheel highway vehicles, such as cars, SUVs and scooters. It is a safe and easy-to-use emergency repair sealant. Use for either 3 days or up to 160km (100 miles) on highway vehicles before visiting a tyre repair specialist. Tyre Pressure Monitoring System (TPMS) Safe. Environmentally friendly, non-toxic, non-corrosive and non-hazardous, non-flammable, water-soluble.
