Review: 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.
Review: 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.

## Questions & Answers

**Q: Is this 2  4 foot pieces or   2  2foot pieces**
A: Two 4ft pieces

**Q: does this fit 0 gauge wire?**
A: Yes it should 3/4 shrinks to 3/8

**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

**Q: can you use a hair dryer instead of a heat gun?**
A: Don't own a heat gun.  Hair dryer and soldering iron work great.  Later not as good for large tube though.
