ALEKOR Heat Shrink Tubing Kit - 3:1 Ratio Adhesive Lined, Marine Grade Shrink Wrap Industrial Heat-Shrink Tubing - 150 PCS

Worked great

I liked it. Use this product on fish hooks to make bait keepers.

These are very pliable and have an adhesive internally that seals it quite well to the wire and have a very good shrink ability when heated. I wish they would come with 1/8" diameter also but these work well.

If you are needing to use shrink tubing on things with connectors, or other bulkier items, this is the stuff you want. The other cheapo 2:1 is fine in a pinch, but this stuff really gets a good seal around the stuff you want to protect.I found this assortment to be generous in the types and sizes, and I like the waterproof adhesive that is on the inside of the tube. This stuff works wonderfully for automotive or outdoor applications, and is miles ahead of anything I have from Harbor Freight.Yes, this might be cheaper than the 2:1 normal stuff, but this stuff is leagues better than that. This stuff is worth every penny.

This comes with a lot of different sizes and works great on the wires.

Briefly: I think this tubing would work well in most places where heat shrink tubing is used. The sizes included should fit the needs of most people. It seems abrasion resistant. The glue seemed to form a tight seal.The 1/2", 5/8" and 3/4" pieces slipped easily on their respective sized rod.I tested the 5/8" tubing with a 4.7 mm (3/16") dowel connected to a piece of 5.74 mm (~15/64") OD tube (see picture). It shrank to create a tight fit that did not leak when I blew hard into the tube. I presume that this is a watertight seal for rain, underground etc. The tubing is some what flexible after shrinking. The tubing length remained approximately 2.4" after shrinking the diameter. I did not have any way to measure the temperature from my heat gun on low setting which worked well to shrink the tubing.It was hard to but possible cut away part of the tubing to separate the parts that were covered. The glue left no residue on the parts that were joined. I think that a wire splice might have had glue residue.I found the count of the 1/8, 3/16, 1/4, 5/8 and ¾ inch tubes to be accurate. I presume the remaining are too.

It does what it's supposed to do. Would like a little more shrink, but it's good enough, and seems water tight. The packaging is great though, and the size sorting guide is a nice touch. Do recommend.

Using this for splicing some low-voltage wire to LED strips. I wish it would shrink a bit more, but overall I am happy with it. It is quite thick ad I do not feel any concern that anything is going to poke through.
