625pcs Heat Shrink Tubing Kit, Heat Shrink Tubes Wire Wrap, Ratio 2:1 Electrical Cable Sleeve Assortment with Storage Case for Long Lasting Insulation Protection by MILAPEAK (8 Sizes, Black)

As a retired automotive repair technician, I am pretty anal when it comes to electrical repairs. I believe in doing it ONCE for the lifetime of the wire being repaired. The only way to ensure this is to provide a WATERPROOF connection. This shrink tubing is exactly the same as the tubing I used professionally. It shrinks tight and seals with the hot glue that lines the inside of the tube. It also remains somewhat flexible after cooling - a quality I look for because cheap tubing will cool hard and brittle, and will crack open if any sideways force is applied to it.

There's not enough of the bigger pieces to make this kit worth anything. Even the "large diameter" kit doesn't have enough pieces to make it worth the asking price. Aliexpress has better deals with the same quality.To the seller, seriously consider reducing your price to $6 for the "small diameter" kit and $7 for the "large diameter" kit to give consumers an actual value price.

These definitely make a good seal and the adhesive easily flows with a heat gun. Tried these with both a heat gun and a butane torch, both with good results. Once sealed, the adhesive provides a very nice water barrier. Be careful using them on fairly over crimped connectors. They may not seal completely on the actual crimp part, which will allow water to still get inside the connection. I used a fairly cheap hydraulic crimp tool, so my results could have been better.Pros:Nice selection of heat shrink for various wire widthsStill slightly flexible after shrinkingThickness is decent, even after heatGood water tight adhesive sealCons:Seems to be more like 2:1 shrinking ratioWould buy again!

This "dual wall" is hands down the biggest PIA. It doesn't fit over any of the connections you want to use it on. And if it does, you have to mash it on there.Good luck trying to use it with insulated connectors. What I mean by that is you will have to find a tube size that will go over the insulation and also shrink enough to wrap the wire tightly. It's not going to happen....I was so determined to use this stuff I bought non insulated connectors. And guess what, it still ain't worth a crap.I have no idea why it's such a PIA to use. I trashed the entire thing. I do alot of crimping with restoration on the cars I work on, and alot of that involved running new wires fixing broken wires etc. I have everything from a hydraulic lug crimpers, ratcheting crimpers with die sets. I love high quality splicing and crimping tools. And this heat shrink tubing is hands down the worst I have ever come across. It's not sized right

There is not much that can go wrong with shrink tubing... so I purchased this kit with little thought. The first time I used the kit I realized that while the product seems to be good, I would be wasting more of it compared to kits with longer tubing.If you use the tubes in the length provided then you are fine, but if you need to cut them down to shorter length then you will end up with lots of tiny bits that you might as well throw away. I use the tubing for electronics projects so I most often need very short tubes. My previous kit had tubes that were the length of the short side of the box of this kit so I could get many short tubes out of one long tube with much less wasted material. Not a big deal but the next kit I buy will likely be with longer tubes again.Other than the issue above, this kit is working fine and the product seems of good quality.

There is the shrink wrap that just shrinks to the wire/connector, then there is the kind like this one, that also glues itself in place! It appears to be made out of a quality material, with a good amount of thickness to do the job. All you gotta do is select the right size you need, slip it on there, then turn on the heat gun, and within seconds, it shrinks down.Some people use a lighter or torch to shrink wrap, I don't recommend that, as you could burn the wire in the process. It is better to use a heat gun, then you can get more even distribution of heat, without damaging the wire. I've used a couple different sizes so far, and its been working out great for me. The glue seems to make a good seal, which should improve water proofing. Highly recommended. 5 out of 5 stars!

I do a lot of work on all terrain vehicles, trailers, and snowmobiles and these are my "go to" tubed heat shrink. It does take a little extra time to start the shrinking process but once it sticks its sticks and creates a nice watertight seal. The seal holds up in the most extreme conditions I could think to put it through.The various sizes included in the packaging are very helpful because I can move from project to project and not worry about having to purchase a different gauge of tube. Almost all of what I use is included in this box.

I am restoring a few old linear power supplies. After cleaning and replacing some of the internal wires, I decided to purchase this dual wall adhesive hear shrink tubing kit to properly isolate adjacent wires soldered to terminal posts, and to shrink wrapped exposed solder lugs carrying AC voltages. Also I used this dual wall adhesive shrink tuning to isolate the exposed ends of copper ring lugs after crimping from one another. This Dual Wall Adhesive Heat Shrink Tubing is working for me, I hope this kit is considered by other Amazon customers. Thank you.
