4 Feet 1" Dual Wall Adhesive Heat Shrink Tubing, Black

If you're looking for wheel barrel handle covers, this is the stuff. Nice and thick, shrinks down tight and mine has lasted 2 years so far, and keep it outside. I'm ordering more for my 3rd wheel barrel. Also worked well on a hammer.

First impression in wrapper they looked like thin not quality heat shrink. But after opening up and cutting to length and heating on my new battery cables I made, this stuff is super thick and good quality sealer. Shrunk at least 3 to 1. I bought 2 more sizes and have used the larger ones. Very happy with this heat shrink.

Works as advertised. It can be slid over the ends of terminals that are already attached, and will shrink a lot more than typical heat shrink to conform to the terminal and wire. I have NOT had any issues with glue melting at ambient temperatures, even 100+ degrees temps we've had in my area lately. In fact, I don't think the glue starts to melt until after the tubing starts to shrink. I've used it on 8 gauge and 10 gauge wire and connectors, so I don't know if this 1/2 inch size would shrink down to fit smaller wire OD. If the vendor sells a 3/8 inch or 5/16 version, that's probably what you'd want for the smaller terminals. Edit: I did some more experimenting with smaller gauge connectors. I couldn't get the shrink tube inside diameter down to less than .200". So I'd say a shrink ratio of 2.5 to 1 is more accurate, at least for the 1/2 inch tube. But I still think it's a nice product and will buy a smaller size if available.

We usually buy by the stick but I wanted a little convenience kit. This one has decent lengths and a few more of the larger sizes than some other kits (still way too many of the smallest sizes, for a 3:1 product...generally you're going to want to be using larger sizes than 2:1 if you want thicker walls after application). The glue is adequate, not quite as strong or as much of it as what we usually buy. With a lighter on this tubing, be aware that it is much easier to overheat and char than some other brands, but a heat gun works fine, and you will come closer to shrinking it all the way 3:1 with a heat gun anyway. So it's decent shrink, perhaps not what you want for some applications like underhood/dash auto where a burn resistant is a smarter option or a 4:1 with thicker walls after shrink. If you've never used any before, with or without the glue even the cheap 3:1 tubing all over the market is a nice step up from the usual 2:1 tubing from just about any brand. Also the red on this kit is a good red - not super vibrant but not leaning toward pink, either.

This is a great kit! the heat shrink is good quality. the sizes are perfect. It's well packaged. You cant go wrong here. Perfect for the automotive hobby or around wiring. The people who sell this kit are good people. The kit came with a note on who and how to contact if there was any concern. Good people selling good stuff!!!!

Made my own battery cables and these worked great on the ends to seal everything up. They have an adhesive on the inside to help stick in place when shrunk and leap things water tight.

Good shrinkage, adequate hot melt to make water proof seal.

would buy again
