Universal Repair String is a fast repair solution but is an emergency and temporary puncture repair seal only. Repair string is an ideal solution for tyres with small punctures and for vehicles such as ATV’s, golf carts and lawn mowers and on radial and bias tyres only. The string is simple and easy to use with an insert tool complete with a slit in the eye, TBDTR18, making those emergency puncture repairs a fast and simple job to complete. However, we strongly recommend that the tyre be demounted and inspected as soon as possible and be replaced with a more permanent puncture repair solution such as a patch or patch plug.
