SO Much More Than Typical Heat Shrink Tubing...

I use heat shrink tubing a fair bit. It is invaluable for sealing an electrical repair or when creating a custom light fixture...
I tried this tubing out since it said that it was waterproof and I wanted to make a connection that would be outside and exposed to the elements...

I had no idea!! This stuff is so cool! At first I was a bit concerned because it seemed HUGE, compared with tubing that I have used in the past...
Not only does it shrink down a HUGE amount to really cinch the connection. It thickens up when doing so, which makes a really nice sturdy thick cover for the wires...

As if that were not awesome enough, it has a heat activated glue inside the tubing which melts as the tubing shrinks and totally seals the entire connection!! This is so much better than typical heat shrink tubing where the seal is tight but not sealed...

I am totally impressed and will be using this type of Heat Shrink tubing almost exclusively from now on...

Great shrink tubing

If you are joining wires without a connector, this is a must-have.
They will keep the connection, either twisted or soldered together, solid and waterproof.
When you supply heat to the wrap it snugs down till glue is oozing out the ends. And it seals all around the wires. Really good value for this!
All-red. I will use that for keeping wires bunched together for a wire harness. Recommended!

Using this was a great emergency fix

My wife was hospitalized for a severe kidney infection and had to wear a nephrosomy bag for a while. While wearing it, the tube came apart. This heat shrink tubing along with a heat gun fixed it. She no longer needs the nephrostomy bag, but I still keep this around. I just wish that I was not limited to giving this product a mere 5 stars.

Extremely high quality!

The perfect amount of adhesive which forms nice sealing bead without oozing and dripping. The material has expected uniform wall thickness and is pliable not stiff and brittle.
Both the tube and the adhesive are resilient that help resist pull away and peeling when a cable is strained at an angle. The crease disappears and the longitudinal shrinkage is only 10% yet the diameter shrinkage is abundant. The amount of heat needed seems to be a tad greater than most others but manageable without damage to the cable. What was ordered was 3/4” by 4 feet and actually measured 4’ 1/4” long. An anti stick tape was in the interior yet the interior didn’t feel tacky at all. It’s probably keep it apart if stored in a high temperature environment like a tool box in the sun. The surface when shrunk is a satin finish and didn’t seem unusually eager to pickup smudges and it wipes off easily. First impression is, it’s probably the best heat shrink for large cable I’ve ever used, but time will tell. Shown is red 2/0 cable with shrunk yellow 3/4” tube.

Works just as expected.

Works better than other brands of heat shrink. Have never had an issue with Bella Bays brand and will continue to stand behind their products. It works just as good as some of the more expensive brands in the industry.
