        There are some low quality Pneumatic Rubber tube in the Market, and they will have the problem of uneven expanding! When using them for a certain time, the part area won't function.

        In addition, their using time is very short, sometimes will result in serious Air Leaking! 

        So, to avoid this situation, we adopted Water Wave Technique for Airshaft inner Bladder to make it more wear-resisting and it can be using for longer time. 

        During production, we deleted All the bubble of the Airshaft Rubber Tube. If the Bubble is to many, it has a higher possibility of exploding or Air leaking.

        In the end, the inner wall of the Airshaft Rubber Tube can guarantee better Hardness and make it more suitable for Air inflation and Air Deflation of the Air expanding Shaft.
