XHF UL Listed 3/4 Inch 10Ft 3:1 Waterproof Heat Shrink Tubing Roll Marine Grade Adhesive Lined Heat Shrink Tube, Insulation Sealing Oil-Proof Wear-Resistant Black

I bought this for the same Sporty Forty style coil I built for my ham radio antenna. After winding the coil with 14 gauge magnet wire, I wanted something to cover everything up and give it a clean finished look. This worked perfect. The 2 inch size fit over my coil and it shrunk down nice and tight. The adhesive inside also gives it a good solid feel once everything cools down. Honestly this was what took the project from looking homemade to looking like something I could’ve bought. Once I was finished, the coil looked just as good as something that came from the factory. The coil works great with my 17-foot whip and gets me on 40 meters, and this was the finishing touch that made the whole thing look professional. Very happy with it and I still have plenty left for the next thing I decide to build.

This heatshrink is legit! Very durable, thick and shrinks very well. Glue sealant inside works well. A bit of info though. 1- 1/4" measurement is diameter of tubing. The width (flat measurement) is almost 2 inches wide FYI. I am using it to seal XT90 connectors for Electric RC boat. Tubing shrinks down to around a 1/2" diameter. See pics

Came in a nice roll! Love it works as it should. Would totally buy again!

These work pretty well for hermetically sealing up electrical connections. The adhesive lining works well. If anyone doesn't see some adhesive starting to ooze out of the ends, that means you're not heating it up hot enough or long enough. Use a heat gun (not a hair dryer). But one thing I discovered through testing is that the adhesive is not really very "fuel resistant". To test it against fuel I shrank some pieces of this around some stainless steel rod. Then I placed those in a jar of gasoline. After only a few hours, the black plastic (polyolefin?) outer part looked okay, but the adhesive had swelled up and oozed out like a big spongy white blob. So I wouldn't count on these holding up long term to fuel. Probably okay for a quick splash of fuel protection though like on the exterior fuel tank sender connections. I used these for some automotive wiring under the car, and I think they'll work great to keep the connections water tight. I wouldn't use them for something like inside of a fuel tank on the fuel sender though. For the price, it's a nice selection of sizes, and a convenient way to store eveything.

I needed to repair a rubber handle on my cast drop forged hatchet. The rubber handle headed deteriorated and I was able to bond it back with contact cement,but I wanted something more to strengthen it up. This did the trick! I purchased 1.5 inch diameter thick wall heat shrink tubing with adhesive. I just took it slow and easy on the low setting of my heat gun and it turned out perfect.

This is a very well made product. I needed something that could shrink at least 2-1/2 times and this 3x stuff did the trick. It is tight gripping and the adhesive liner adds to that feature. Now, I am using this in an outdoor application, so it will take some time for me to assess how durable it is. For now I am very pleased.

I had almost given up on tubing but this stuff is great! Heavy duty! Heat it until the waterproofing goo comes out of the ends. So much better than the old school thin stuff!

Shrunk down, adhesive at both ends. Used on 10 mm pipe so cannot say if 3 to 1, However same stuff 1 inch shrank to 10 mm with adhesive both ends, so this probably does too. Bought both just in case some review said shrink was less than 3 to 1. I used a proper heat gun for these results

Works great for grip on picks

Used it to seal and waterproof a marine antenna that was previously cracked. Used epoxy and fibreglass to repair it. Then used the 1” shrink tubing to seal it. Worked great and the colour matched the colour of the antenna.

Should have ought this type a long time ago. It has adhesive on the inside and guarantees waterproofing it is all thicker material and shrinkage is very good goes down to a small size

Work as intended I got the clear ones perfect .. the fold doesn't impact the product
