Do you know the most key part of an inflatable paddle is the valve?

How do you keep the paddleboard air-tight?

The most important point of the inflatable paddle is: no air leakage in half a year, the air valve should be put 0.7 thick PVC skin, the air valve can not use screws inside, the spring must be high material stainless steel material, the bottom mouth must be imported TPU seal, in addition, the wrench must be tightened again in the packaging process! That's half a circle! These materila and work can ensure that the air valve does not leak, there is a air valve material must be PA66, the thread should also be diagonal and upwards.

The above is my experience of 20 years in making paddleboard, Provide professional exchange learning.
