RockDIG 74PCS 1 3/4 1/2 3/8 Inch 3:1 Heat Shrink Tubing Assortment Kit Double-Wall Adhesive Lined Marine Grade Industrial Heat-Shrink Wrap Wire Tubing Black Red

Unfortunately, the shrink tubing I received did not have the adhesive inside. I was bummed! I didn't catch it until I was past my return date.

Good assortment

It's good heavy heat shrink with decent glue, and it being 3:1 makes it super versatile

Excellent in every way, large selection of sizes and quite a few in number. Very good price, and they provide insulation as well as mechanical support for whatever they are used on. They do require a lot of heat for a short time to properly fuse. You need to be careful of overheating your work. This is a common problem for all of this kind of joint insulation.

i chose the product i needed carefully to do what i needed them to do. They done just that. They made me look good. They made me feel proud.

professional look and protection for battery cables and smaller wiring

Works as advertised. You heat, it shrinks. Decent case.

Pleasantly surprised. Went to cover some 4ga battery lugs and the tubes looked way too big. Tested one by putting it on a screwdriver. I didn't expect it to shrink that much, but wanted to see how far it went. It shrunk all the way down and glued to the screwdriver. Very pleased. Good thickness - nice and heavy over the lugs. Another nice feature - they are so big you don't have to remember to put the shrink on before you crimp the connector - plenty big enough to slide on after you crimp. Haven't checked, but I would also like some that are a bit smaller, for smaller gauge wires (18-20ga tefzel, unshielded, for example.)

What a handy pack of heat shrink tubing. So many sizes and the shrink worked perfectly every time. I used them installing a new Lowrance HDS unit in my boat, and adhesive heat shrink is a must for marine/high moisture applications and these worked great!

Sofar I have used 2 sizes of heat shrink in multiple colors. The 3:1 tubes are easy to cut, shrink fast when heated with heat gun, and do not split or burn. There is heat-melt adhesive inside the tubing, meaning it seals the ends and you can see it ooze out. Be careful not to overheat the tubing (I was used to other tubing which didn't shrink as well and needed more heat, so I burned my test tubing setup. Very good value for money.

Kids are terrible with the cable chargers. I can’t count anymore on how many cables was damaged. By having this, pretty sure it will hold up longer. Use heat gun to shrink and it’s very easy.

Good kit but they are a bit stiff and need more heat to shring them

Shrinks tight...the way you want it to....
