KABLE KONTROLHeat Shrink Tape - 1" Inch Wide - 16.5 Ft Rolls - 4:1 Adhesive Lined Shrinkable Tape for Electrical Cables, Wires, Pipes – Adhesive Activates Upon Heating Melts and Seals, RoHS - Black

I had a leaking kitchen, 1-1/4" Cu drainpipe, located in a tight, wood floor joist area (picture). I am familiar with Heat Shrink materials, and I choose to use the 1" Heat Shrink tape for repairs. Several reviews I read were critical of this tape (flexibility and wrapping difficulty). What I found was the 1" tape, being about 1/32"+ thick, wrapped but not as tightly as I thought it should due to its thickness. Starting and ending the tape wrap seemed difficult (holding the tape in place during the wrap process) until I used electrical tape on the heat shrink tape ends to secure the tape. I started the wrap about 2" away from the critical area of the leak and ended the wrap about 1" from the critical area. The tape has about a 2 to 1 shrink ratio, so I did not have to have the tape tight, just snug and fairly flat to the work surface. On one side of the tape is a shiny glue compound (See Picture). It does not become sticky and gluey until heat is applied to the tape. On heating the tape via Heat Gun, the heat shrink tape shrunk tightly to the pipe and itself, and the glue on the tape became soft and squeezed out the edges of the tape sealing the tape to itself and the pipe. Be sure to heat from the center of the wrap to the ends of the wrap. The end product was a tight patch resolving my leaking pipe problem. I tried several other ways to solve the leak, and this one ended up being the most simple and effective method. I did not use a torch in fear of starting a fire in my walls. Hope this helps you!

This product is VERY difficult to use. When I called the company, they told me to use zip ties to hold it down while I wrap the tape. It is so thick, that it doesn't lend itself to wrapping without difficulty. Even after I applied the tape and used the heat gun to seal the tape, It did not hold very well.I would not buy this product again. I should have asked for a refund after my first two attempts.

This tape is heavier than i expected. I was taping headset wires so this is overkill. The tape has a glue backing that held in place while i heated and secured it in place. It was a bit difficult because the wire were so small. A great product for large projects. It works have been nice to understand how heavy this tape is so some level of measure in the product description would be appreciated.

Perfect for sealing connector fitting - wrap and heat.

It's ok at best, will not stick to itself until heated. Very thick material. Hard to wrap tight and keep it tight while heating

I just recently discovered this product. I was familiar with shrink tubing but what if you can't slide it over an end or what if you have a cable to cover or a 3 way connection? This product is perfect for those types of applications.

Used in my 1970 BMW. Easy to work with and created a good seal using a heat gun

This tape is useless! It does not stick to itself! I wrapped it around the large harness I wanted to cover. I tried to hold it with my fingers while heating it, ouch! Does not work, do not buy!
