XHF UL Listed 1/2 Inch 10Ft 3:1 Waterproof Heat Shrink Tubing Roll Marine Grade Adhesive Lined Heat Shrink Tube, Insulation Sealing Oil-Proof Wear-Resistant Black

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!

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 really want to give this 5 stars because it is great tubing, but knocking one off because the 2" clear does not have any glue as stated. As it turns out, this was better for my application and the clear is a bit more cushy/flexible than the color are, so all is well. The only clear I've ever used was very small diameter and it was known glueless tubing...maybe it's normal with clear and the XHF normal colored tubing has glue like usual. But this is good stuff. Longitudinal shrink is almost zero, which is great. It does do a full 3:1 shrink but you'll need a heat gun, not just a hair dryer (or god forbid, a lighter) - you can do those methods with smaller 2:1 tubing but if you want the full shrink on 3:1 and in medium to larger sizes, you need better heat application. In the photo is some 1.5" black 3:1 from TEMCo and this 2" clear from XHF. Fully shrunk it's around 11/16" diameter with a good thick wall (almost like PEX pipe but softer...stiffer than PVC/vinyl tubing). It's noticeably softer than any black/red tubing I've used but it's till rigid enough to support and protect - grabs more dust than the colors and may be more prone to abrasion but this is still soft shrink tubing, not a jacket. I guess heed the glue warning if that's important to you, but otherwise highly recommended and I'll buy some other sizes from XHF in the future. Some of the 3:1 tubing out there isn't very good or just so-so, but this brand and the TEMCo are both excellent.

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!

The power pole Spikes on my boat were starting to get a little splintered from the sun. After my buddies kid got some fiber glass stuck in his legs, I decided to give this a shot. Works like a charm! Also made them look nice again. Once roll did 2 with extra material left over. I assume this should hold up for a long time.

Incredible definitely works as should

This is truly a good product. I used it to repair a severed and nicked up outdoor extension cord that was run over by a tractor lawnmower. I used the 3/4 inch diameter. The material is plenty thick for protection and the glue slightly oozes out when finished. I would definitely buy this again.

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

Corresponds to the description

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