1. The quickly change valve tool kit is suitable for leakage valve stems. It allows replacing the valve stem without disassembling tires. It features a solid steel structure and an industrial-grade nylon handle, and can replace the tire valve within 15 seconds. 2. T-shaped hooks can quickly pull out the valve core. The cone positioning tube provides guidance and positioning when installing a valve core. The metal push pole can accurately push the valve core into the pillar hole. Our engineers have repeatedly improved and tested the product structure and product materials. 3. Our tools are suitable for most edge holes with 11.3 mm (0.453 inches). They are not suitable for 5/8 inches (15.8 mm) valve cores or tires with a tire pressure monitoring system (TPMS). They are suitable for cars, small trailers, light trucks, grass cutters, single-wheels, all-terrain vehicles and motorcycles. 4. Steps: 1. Deflate the tire; 2. Insert the T-shaped hook between the hub and the valve core, rotate the hook to pull out the valve core; 3. Install the valve core on the push pole; 4. Align the cone-shaped positioning with the valve holes, and install the valve core through the cone-shaped positioning tube; 5. Rotate the push rod to break away from the valve core. 5. Type: A 6.
