1.5 inch (Diameter) 3:1 Waterproof Heat Shrink Tubing Kit, Large Marine Dual Wall Adhesive Shrinkable Wire Wrap Tube, Insulation Sealing Wear-Resistant Cable Protector by YUKSY (4ft, Black)

The media could not be loaded. I do like this shrink wrap. I use it mostly on #4, #2 & 2/0 wire in my solar system and batteries. I tested it on a piece of #4, which is 1/2" thick and it worked really well. (see video and images). I used a heat gun and it shrinks up real nice, doesn't burn or curl up. This is 3/4" diameter shrink wrap and I was really surprised that it shrank all the way down to 1/4".Highly recommended. JohnnyF

I used this over a long, jagged break in a supporting pole on a PVC pipe structure. The repair worked and has held up for months.

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 :)

PRODUCT IS USED TO WRAP CYLINDERS THAT ARE TO BE PRESSURE TESTED FOR AIR LEAKS.

It worked as expected

It's shrink tube I used it to cover some electrical clamps so it doesn't damage the painted part I was clamping!

Good quality tube. Will shrink to fit 350 mcm.
