XHF 205 PCS Length 3.5" White 3:1 Waterproof Automotive Electrical Heat Shrink Tubing Assortment Kit Large Size Marine Grade Adhesive Lined 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.

Work great and I love the internal siliconeMake for a water tight seal

You can write on them before shrinking them and the letters stay clear and readable.

I'm a radio broadcast engineer and find myself making cables for various equipment as parts are either no longer manufactured or are just difficult to get due to the idiotic supply chain issues. So I bought some cable here on Amazon, bought the end cable lugs, again here on Amazon, and also got this set of shrink tubing to dress up the cable ends.It's a nice set with a great variety of sizes. The plastic carry cause is good enough quality where it does not come apart after a couple of uses. I've uses different sizes for various projects so far and the tubing shrinks up evenly when heat is applied. I've done 3 transmitter repairs and did a home cabling project and so far so good.It's a good value set.

Spliced and wrapped 2 low voltage wires then those together. Ended up using 3 sizes and they shrunk down snug. The white matched my wiring and looks great on under cabinet lights.
