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.

### ⭐⭐⭐⭐⭐ Works well, but....
*by A***R on January 31, 2026*

This shrink tubing works fine. My only criticism is that it gets rather hard and unformable once it cools off. You may not care based on your application. It didn't really affect mine too much. But I don't know if this would be the best if you needed to wrap a set of wires and then tightly coil them.
