Engineers have made many improvements and achieved seven major performance improvements. With proficiency, you can quickly replace the valve in 15 seconds:

Improved stability: The outer side of the tapered positioning tube is designed with grooves and convex rings, which greatly improves the friction of the hand and helps to provide more accurate positioning during the installation process.

Improved durability: The tapered positioning tube is made of high-strength plastic material and the tube wall is thickened to make it stronger and more durable.

Improved versatility: Optimized the aperture size of the cone part of the tapered positioning tube to adapt to more wheel hubs of different specifications

Improved convenience: The inner wall of the sleeve is smoothed and used with lubricating oil to reduce propulsion resistance and effectively protect the new valve.

Reliability improvement: The plum blossom handle of the push rod grip is thickened to enhance palm control, advance the valve more stably, improve the installation success rate, and advance the valve faster

Improved installation efficiency: The end of the T-shaped hook is chamfered. When hooking out the old valve, it can be pulled out of the rim more easily to prevent it from being stuck in the rim valve hole.

Improved safety: The T-hook handle end is welded through and wrapped in plastic, which reduces the safety risk of scratching your hands when installing with force and improves safety.
