Review on XHF 205 PCS 3.5" 3:1 Adhesive-Lined Heat Shrink Tubing Kit For Auto And Marine Applications by James Mcphearson
Yes, the sealing feature is there
There are many reviews saying that it will not seal, but it did for me. You do need to apply quite a bit of heat before the seal will start oozing out, and I am not sure that I hair dryer would be enough heat (I use a heat gun). End result was perfect! (see pics)
Pros
- I love that I can used these to further customize my projects. I will order more as needed.
Cons
- May not be as strong as other tubing options
