Waterproof heat shrinkable connecter , also named duraseal heat shrinkable crimp splice . We introduced it many times , it is made up of PE heat shrink tubing and copper pillar .
The function of heat shrink tubing is fixed the outer of cable and make it waterproof , The function of copper pillar is connect the metal wire of 2 cables .
One of our customer asked some sample from us , and they told us it is not waterproof connecter , because they can not see any adhesive inside . We found the reason why they said that , maybe it is the first time using Waterproof heat shrinkable connecter . They just connected the metal wire , even did not heat the heat shrink tubing , so it can not cover his cable , and the adhesive did not melt without heat .
It is the picture we took yesterday , you can see the adhesive clearly when the heat shrink tubing completely shrink .
Anybody do not know how to use it , we can provide you operating video .
