Extend the Valve This valve extension will make it easier to inflate your tires. No pressure loss thanks to the non-return valve. The extended valve design allows you to inflate your electric scooter more easily. Strong Compatibility The valve extension is compatible with electric scooters and also other types of vehicles such as cars, motorcycles, trucks and bicycles. The size of the valves is standard for different types of tires. Anti-leak This valve extension is equipped with a non-return ball. This allows you not to lose air when you disconnect your inflator. And unlike flexible extensions, this extension is rigid and therefore unscrews very quickly and easily. Efficient Thanks to the valve extension, you can find the tire valve more easily, effectively buckle the pump inflation nozzle, and then save your time. Appropriate Length This extension can be extended by 3.9 cm, which is a perfect length. You can easily buckle or unplug the inflatable nozzle without scratching people because the length is too long. Note: The data are all measured manually, please allow an error of 1-3 cm due to differences in light and display, there may be color differences, please refer to the actual item received.
