XHF 205 PCS Length 3.5" Black 3:1 Heat Shrink Tubing Assortment Kit Large Size Marine Grade Adhesive Lined Waterproof Automotive Electrical Tube, Insulation Sealing

I used this to stabilize the old brittle cloth and rubber insulation in the electrical boxes in my home. The piece of mind is incalculable. It's super easy to use, feels at least as thick/durable as factory wire insulation and it shrinks MORE than 3:1 in diameter without loosing ANY length at the low setting of my heat gun.To address 3 complaints I saw in negative reviews;It does shrink MORE than 3:1. Remeber it contains an interior adhesive layer AND when you shrink the plastic, it doesnt magically dissapear, it collapses on itself, getting thicker... so while the OD (outside diameter) may not appear to do so in one posted image, the ID (inside diameter) which is what matters, shrinks more than 3:1. The 1/4" will shrink tight over a single bare 12 guage wire.The other complaint I noticed was about the case. The case I got is very good quality, of flexible durable and clear plastic with hinged plastic locks (not just fold tabs, I hate fold tab locks) and a hang tab for store display that works great on peg boards. I'm a freak about tool room storage. I dont have a single jar of screws.. everything is separated labeled, i probably spend as much on storage solutions as I do on tools. I'm not even the least bit tempted to replace it. The only issue is that it comes with 8 sizes of sleeve in a container that has 4 compartments, but that's really nitpicking.The last reason I saw for negative reviews was they are too long. This is never a bad thing. It's easy to trim with a scissor to any size you need. Too short and you're out of luck..Too long? Not a problem. Cut what you need and save the rest of the next time.

Nice assortment of sizes, works great!

Great shrink tubing, seals and secures your connection.

This is a good kit and was worth the price I paid. Used to repair and modify Some holiday lights and some t5 led wiring.Only thing to make it better would be more variety of sizes amd they were not very well sorted in the box.

I'm happy with this shrink tubing so far. It does seem to have a 3:1 shrink ratio. And it does have heat-activated adhesive because you can see a little bit ooze out the ends when you shrink the tubing with heat. I needed gasoline-resistant heat shrink tubing, although they do no claim such in the listing. Another reviewer said they used it in a fuel tank application, so I figured I'd give it a try. I have a piece soaking in gasoline and it seems to be holding up OK after a couple of weeks.

works great, I use it for electrical repairs.and model boat building.

I didn't use this as intended but they are great. Great shrink ratio. Just with ir came with more 3/4". Used them to make a nice water proof labels for my hand tools.

Shrink tubing is one of those things that is super expensive when you buy it in small quantities. This box comes with a great selection of sizes. I bought this to use on the arms of my glasses. The arms are very thin and dig into my ears a little. They are now much more comfortable after putting a piece of this tubing in place. I also like having clear tubing for covering some of my electrical connections. You can see if things start to corrode.
