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. 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: The good stuff - Review is for 3/4 inch This is not the cheep thin stuff. It shrunk tight on the 2 gage wire and lug. Some glue came out the ends and sealed well.

### ⭐⭐⭐⭐⭐ The good stuff
*by G***. on August 10, 2026*

Review is for 3/4 inch This is not the cheep thin stuff. It shrunk tight on the 2 gage wire and lug. Some glue came out the ends and sealed well.

### ⭐⭐⭐⭐⭐ Mostly "as advertised." Works Well
*by P***G on February 9, 2023*

This is a good product. The reason I say "mostly as advertised" is because the (Red and Black) tubing I purchased was advertised at 1/2" in diameter, but the Red tubing was a bit larger. The diameter of the Black tubing was dead on as advertised but the Red tubing was 0.11" (2.7mm) larger than 1/2" (I measured the tubing with an outside micrometer). However, since this tubing has a (higher than usual) 3:1 shrink ratio the slightly larger diameter of the Red tubing did NOT cause any problem for the project on which I used it (the only reason I mentioned this is because the slightly larger Red tubing "might" affect others who may need a precise 1/2" size). Even with this minor hiccup, I still gave this shrink tubing 5 Stars. It did shrink 3:1 which allowed me to replace two other sizes (1/2" and 3/8" with 2:1 shrink ratios) with this single size. Additionally, the marine glue/adhesive worked exactly like the picture showed. I did, however, notice that a number of other reviews mentioned that the tubing they received was not the diameter advertised. So the seller needs to address/correct this. I would definitely purchase this shrinkable tubing again.
