1/4 Inch Heat Shrink Tubing - 16.5Ft 3:1Ratio Waterproof Heat Shrink Tubin - Adhesive Lined,Dual Wall Adhesive Shrinkable Wire Wrap Tube - Black

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.

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.

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.

Seems to seal up and work without splitting like I have had with other in the past. The package is a little odd in that it is wrapped around cardboard then vacuum sealed so it puts some kinks in the tube. But I just used the area around that. I’m sure it may take those out if layed out to relax a bit. I think rolled up onto a tube would be much better.

It shrinks the tubing evenly.

I had to replace the batteries in my bike's TPMS sensors. To do so, you have to pull the housings apart. Your options at that point usually involve gluing them back together. I decided to try some heat shrink to hold them together. The 1.5" was too large, but this 3/4" was a good fit. This has a decent wall thickness and the adhesive was what I needed. It's a good value.

Works great! Used it to fix my vacuum lines for my truck. No vacuum leaks anymore.

I thought I was getting a half inch and I actually got closer to an inch. It made it a little too big for what I needed it for but if I constantly heat it up it would shrink down to just fit. Not snug but enough to not create a problem. Unfortunately heating it that much caused the solder joints to melt. So I had to take the tubing off and resolder the connection. That's when I learned I needed to heat it just a little bit, wait for it to cool down and then heat it up some more. And keep repeating this until it became small enough and not melt my solder points. The glue on the inside makes it great to work with because it cuts out moisture and seals the connection. So my only problem is is that it's too big for what I needed. So maybe I'll find something else around the house I can use this on. The product is great but the sizing is off and that's why I can't give you five stars. I didn't get what I order. Even though the packaging says otherwise.

Great product will buy again if needed. Note: disappointed logistics guy left my item on the chair not door step.
