GRAND PITSTOP repair kit is a practical solution for tire maintenance, ensuring safety and performance. It provides puncture repair for tubeless tires with holes smaller than 5/16 inches on all road vehicles. Featuring an automatic mechanism, it completes the task easily without removing the wheel, saving effort and time. The mushroom plug acts as a rivet, creating a secure fit to prevent air loss: the head fixes the puncture from the inside, while the stem seals the puncture line. The stainless steel nozzle is corrosion-resistant and durable. Its lightweight design ensures easy transport. No rubber glue or lubricant is required.
