Once installed into the tyre, SLIME remains a liquid- evenly coating the inside. When a puncture occurs, the escaping air forces SLIME into the hole where it creates a long lasting, flexible plug. Non Flammable. Non Toxic. Non-hazardous-water soluble formula. Instantly seals punctures in the tread area up to 1/8". Slime lite is a lightweight version. Weight 219g per tube.
