31 Incorporated 12-360 4in Fat Brown String (Box of 30)

ALL X-tra Seal inserts perform the function of filling the injury as recommended by the RMA and other industry associations. String-Type inserts can be used in passenger or truck, radial, or bias-ply tires. Made of a butyl rubber, these inserts are very strong, allowing easy insertion through steel belted radial tires. String-Type inserts are TEMPORARY repairs, sealing by compression only. Use a passenger length end-slot needle for installation.
