heat shrink tubing

It works exactly as expected with 3:1 shrink and adhesive lining. Good value for the price.

Lyford Texas
Many uses. Great product.

Well I tried to upload a video and your system would not allow it. This is a great product. I used it to make my own speaker cables. It looks much better after using a heat gun.

Brittany Mitchell
Surprisingly great value.

This stuff surprised me! There isn’t a TON of glue but there’s enough to see it slooge out the ends when it shrinks and that’s enough to make it weather tight so it gets an A+ from me. Plus the 3:1 ratio means if you (or rather WHEN you) forget to put the heat shrink on before your termination you can get a slightly bigger size to fit over the termination and still shrink down just fine.
