Review: You cant go wrong with this one - 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.

It’s a must-have for anyone looking to ensure their electrical connections are protected and long-lasting.
Review: Quality and good thickness. Shrinks from 3/4 down to 1/4". Recommended. - 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

**Q: can i use a lighter to shrink it?**
A: Yes but you will burn your fingers.... this is much more heavy duty than the little shrink wrap tubes most places carry.... it shrinks to about a half inch in diameter and probably close to 1/8 inch  wall thickness.... 
I used a heat gun to shrink it. I advise the same

A: Don't own a heat gun.  Hair dryer and soldering iron work great.  Later not as good for large tube though.
