Sumitube W3B2 - made in Japan high tech 3:1 dual wall shrink tube
Click here to link to Sumitomo’s website for a data sheet.
I have selected the best shrink tube in the world for all my Kits and now I’m selling it to you so you can use it at home on all your DIY projects.
This shrink tube is unlike anything you have ever used or seen. It’s incredible! Sumitube W3B2 totally waterproofs your connector or terminal!
Sumitube W3B2 has an inner layer of clear glue that melts and completely encapsulated the terminal or connection. Not only does Sumitube W3B2 completely waterproof your connection, but it provides the ultimate wire strain relief.
Sumitube W3B2 shrinks 3 to 1 so you can cover a large terminal and still tightly wrap a thin wire in the same connection. Here below are some finished samples from my own production.
