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

I've been super impressed with this heat shrink. It shrinks up really well, has plenty of adhesive inside to seal and rarely melts through, even when I use a torch to shrink it. It's a decent selection and feels heavy duty. A lot of heat shrink you can feel is just super thin, this stuff is much better. When I run out I'll buy this brand again.

I had a broken vacuum hose and after sealing the break with silicone tape, this went over it as a very strong protective layer.

These worked great for I used them for, which was non-electrical. I made some antenna mast guy "wires" using 3/16" starter rope and wrapped the end around a rope thimble to form a loop. I used this shrink tube to secure the end of the rope. I used a mini heat gun with the high (800 degree) setting, the tubing shrank right down and everything is secure.Did not encounter any of the issues mentioned in other review, it's not thin or fragile stuff, it shrank down without any difficulty. The length of the tubing in this set runs from 1-3/4" to 3", depending on the diameter size.What you see in my pic is a 3" piece cut into two 1-1/2" pieces.

Buena inversión

Perfect for what I needed.

Fabulous product thanks for the product

These heat-shrinks are really great! They’re thick & durable and shrink to a ration of 3:1 (or more)! They’re easy to use and take no time at all to heat up

maybe I'm shrinking them too fast, but if you have any kind of irregularity underneath there's a very high change the sleeve will tear as it shrinks over the irregularity. I feel like a little more thickness might help. That said, they adhere great due to some glue or other kind of bonding compound inside the sleeve. I've only used the large diameter ones on battery cables for industrial equipment. I suspect the small diameter ones may be less prone to the tearing problem just due to less % shrinking
