Fiber Seal Plugs are gray vulcanizing gum coated, wrapped in a blue protective poly, and have a reinforcing core of fiber designed to allow their easy insertion through steel belted passenger radial tires. Unlike competitive products that are fabric throughout (forcing the injury to take the shape of the insert), Fiber Seal Plugs have a large amount of rubber coating, allowing the insert to conform to the injury. Fiber Seal Plugs will vulcanize chemically or in a heat curing system. Use any end-slot needle for installation.
