2 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

Great product and price

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 have had better for the price not so bad the red like some coloration but for general purpose for the price point I would have to say not too bad.

I recently used the 2 Pcs 1 inch (Diameter) 3:1 Waterproof Heat Shrink Tubing Kit for a few marine wiring projects, which exceeded my expectations. The dual-wall adhesive feature ensures a tight, waterproof seal, essential for the durability and safety of electrical connections in marine environments.The 3:1 shrink ratio is impressive. This allows the tubing to conform perfectly to the wires and connectors, providing a secure and professional-looking finish. The large diameter size is versatile and fits various applications, making it a handy addition to my toolkit.One thing I particularly appreciated was the quality of the material. The tubing is robust and resilient yet flexible enough to work with efficiently. It protects against abrasion and environmental stress, which is crucial for outdoor and marine use.Overall, the 2 Pcs 1 inch (Diameter) 3:1 Waterproof Heat Shrink Tubing Kit is a reliable and high-quality product that offers excellent value for money. It’s a must-have for anyone looking to ensure their electrical connections are protected and long-lasting.

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 :)

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!
