Review: Very high quality. Used for aluminium pole repair. - I had a snapped and bent aluminum boat canopy frame which I had straightened and repaired with tube inserts and rivets. Fine as far as it goes but I had the bright idea of encasing it in heat shrink to prevent any rough spots damaging the canopy, and to disguise the agricultural nature of the repair in general. I tested several different types of heat shrink, and this one is the clear winner. It is nice and thick, looks great, and I was able to shrink 5 metres of it with a blowtorch without scorching it at all. Add to that its excellent substrate of hot glue, and it's even strengthened the poles somewhat by laminating them. I'm absolutely delighted with the result, which would not have been possible with an inferior product.
Review: You pay for quality - Good quality but pricey, but if you are protecting electrics, then this is the one. Wish it came in shorter lengths, so I could have gotten a size down too. Shrinkage is uniform, have to cut open to re do and the wire comes away neatly which is also a bonus. Very durable but measured diameter wrong, but that's on me. I've used this on all my bikes wiring and seems solid so far.

## Features

- 3:1 SHRINK RATIO - Recovers to 1/3 of its original diameter, and makes a tight seal. Eliminates the problem of 2:1 tubing not shrinking tight enough.
- GLUE INSIDE - When heat is applied, adhesive comes out and seals the connection. This creates waterproof and long-lasting insulation.
- EASY TO USE - Simply slide heat shrink tube over your connection point and apply heat. Make professional insulated connections in seconds.
- DUAL WALL TUBING - Provides enhanced protection from wear and tear. Industrial grade tubing is resistant to fluids, heat, and mechanical stretch.
- 1/8 INCH (3.2mm) SHRINK TUBING DIAMETER - Get the exact diameter you need. 50 Feet of shrink tubing will last through many projects.

### ⭐⭐⭐⭐⭐ Excellent Adhesive Heatshrink
*by M***S on 18 August 2023*

It works exactly as I hoped. Some reviews said that the tubing walls were very thick but I found them to be perfect and actually thinner than some other tubing I've used. I also noted that it does a genuine 3:1 heat shrink as well. Very happy and highly recommended.
