desertcart.com: 1/2 Inch(12.7mm) Heat Shrink Tubing - 10 Ft 3:1Ratio Waterproof Heat Shrink Tubing,1/2" Pre-Shrink Diameter,0.17" Shrunk, Adhesive Lined, Dual Wall Adhesive Shrinkable Wire Wrap Tube : Industrial & Scientific

Review: Good quality product. - Works as it should. I ordered this large size so I could repair three wire cords. Each individual wire is repaired and appropriate size heat shrink used and then this one is put over all three. ai love heat shrink that has adhesive inside because it helps make a connection dependably water proof. If shrunk down well when heated and had an adequate amount of adhesive inside so as to create a waterproof seal.
Review: Flexible and Effective for Automotive Wiring - I recently used the 3/8 Inch Heat Shrink Tubing in my Jeep for some wiring projects, and it worked really well. The 3:1 ratio provides a solid shrink and tight fit, and the adhesive-lined, dual-wall design ensures a durable seal. One of the standout features for me was how flexible the tubing is. It was easy to route around corners and fit into tighter spaces, which is often a challenge when working inside a vehicle. The waterproof nature of the tubing also gives me confidence that it will provide long-lasting protection against moisture and corrosion, which is important for any automotive electrical work. It shrinks evenly and securely when heat is applied, providing reliable insulation for the wires inside. Overall, this tubing is a great option for automotive wiring, especially when you need something that’s flexible enough for tight spaces but still provides the protection and sealing you need. It worked perfectly for my Jeep and I’d recommend it for similar applications.

### ⭐⭐⭐⭐⭐ Good for the money
*by K***H on November 10, 2025*

So if I'm not mistaken I got this in blue and it was used to tie up the ends of this blue net wrapping that I was putting over my vacuum hoses to doll up my engine bay a bit. Seems like decent quality stuff. The he activated glue on the inside gets annoying after a while but it's there for a reason. The color could have been a bit more vibrant but wouldn't say it's bad. Worked well to protect the edges of the netting to keep it from fraying out.
