Don't waste your money on this heat shrink tubing. It is made from inferior materials. Every time I try to attach this hose to a part it melts. Using a standard heat gun will melt this tube or create a hole. I have used heat shrink tubing for miles but this is the worst product I have ever seen. I wouldn't recommend it even for very light use. . Just wasted money that could have been spent on a better product. At the time of writing this article, I have found the best supplier of quality heat shrink tubing. I gave 1 star because I couldn't give 0.
