Heat Shrink Tubing Kit

I tried to fix this cable with a different heat shrink tubing. That tubing had a shrink ratio of 2:1. If you use a diameter large enough to fit over the thunderbolt connector, the 2:1 shrink would not shrink tight around the cable. This tubing is a 4:1 shrink ratio and it worked perfectly. It also has some glue inside the tubing which will glue the shrunk tubing around the cable. Not sure I need that and would make it difficult to remove if I had to, but now that it is on, the glue really makes it a solid fix. I also used Bondic inside the tubing to seal the split cable insulation. Recommended for any application like a cable with a connector that you need to pass over.

Been a fan of 3 to 1 shrink for a while. Wanted to try 4 to 1 in a few applications where 2 layers of 3 to 1 were needed. This stuff did it in one layer.

Nice heat shrink, a large collection of sizes, useful for any application. I use it to tie down some nylon braided to a GPU cable and worked great. Make sure you don't hear too long.

I used the 8mm tubing on my macbok pro mid 2012 charging cabel, which had the rubber exterior starting to peel off at one point near the adapter at the computer end. Slid it over the adapter to rest on the failing cable section, and shrunk it down. Now a repaired and stronger cable, and looks clean. I specifically got this for 4:1 ratio, so that the 8mm would shrink down to the 3mm cord. PERFECT.

I needed some super-shrinking tubing to use when I couldn't cut a connection off and this did the trick. WARNING, it super-shrinks both in diameter AND length compared to normal shrink tubing. Adhesive is a bit messy, but cleans up easy enough.

good shrink

good product

4-1 shrinkage seems to be accurate, and the adhesive seals and waterproofs effectively. When cooled any excess adhesive squeeze out is hard and clear, not sticky.

works as described.
