2 Pcs 1/2 inch (Diameter) 3:1 Waterproof Heat Shrink Tubing Kit, Large Marine Dual Wall Adhesive Shrinkable Wire Wrap Tube, Insulation Sealing Cable Protector by YUKSY (4ft, Black & Red)

I was just looking for a quick roll of red & black shrink tubing to finish off some power cables for my solar installations and snagged these without really looking. I was VERY pleasantly surprised when I put them to use and saw the clear substance like hot-glue-gun glue form a very thin ring at the ends of the connection's tubing. I looked at the inside of an unused section and realized that was effectively what it was! These seal really, really well, forming what I would expect to be a water-tight and very reliable finishing-touch to your custom cable making. Very happy I discovered this stuff, I didn't even know before this that such a hybrid shrink tubing existed. I will definitely be buying more of this stuff! I'd give it 6 stars if I could :)

shrinks quickly

works as expected

I bought this to rubberize my tool handles. Works great, nice finish!

Best heat shrink i have ever used. excellent thickness. Grips very tight and is firm once cooled. Even shrink without distortion and the glue is strong.

Shipped fast

I used this to complete a repair to the wiring on my cargo trailer with a 7-wire cord. It had gotten damaged in use and I had to splice several wires back together. Then wrapped the whole thing with electrical tape but that's not weatherproof. So I cut a section of this tubing and was able to slide it over the wiring plug and shrink it down to completely seal over the repaired section about eight inches long. I think the wiring is as good as new now and certainly well protected. You do need a good powerful heat gun, and you need to be patient and work slowly to shrink it to final size.

Worked as I needed it to.

Very nice . This is the best heat shrink i have ever used. Nice and thick and the glue inside them seals good. If you want factory like results. Then get yeah some. i plan to soon as i need more.

I am really impressed with the quality of this thing! The addition of glue to seal the entire thing is genius. It shrinks evenly and also it has a good thickness! You won't be afraid to tear it apart like some other brands. Love it!

Accurate sizing consistent shrink rate

This did what was stated. It took a little bit more heat to get it to start shrinking. Be careful of what you are trying to cover with this shrink. Other than that it did the job for me just fine.

Identify and seal ground cables.
