HOPSON Universal String Inserts are a quick and efficient solution for repairing minor damage in tubeless tires. The unique gray cushion gum flows into the injury, sealing the inner liner as well as broken cords and cable ends. These inserts permanently vulcanize to the tire, making it immediately ready for use. They are suitable for both bias and steel-belted radial tires. Designed for demounted tires, they also work well during retreading processes. When used with the appropriate repair unit, they provide effective and long-lasting repairs. Note: Industry standards recommend that tires should be demounted and repaired from the inside using inserts and the proper repair unit on the inner liner.


Features:
Universal string inserts are compatible with both passenger and truck tires, as well as radial and bias-ply tires. Made from high-quality butyl rubber, they are strong and easy to insert even through steel-belted radials. These inserts are temporary repairs that seal by compression only.
