Marine Grade 3:1 Waterproof Heat Shrink Tubing Wire Cable Adhesive Lined Tube Insulation Seal, 1 Inch (25mm)

jb: My Cushcraft A4 trap end caps had rotted out (again). This stuff fits perfectly and shrinks enough to seal nicely to the smaller tubing.

Yes, there's adhesive unlike what some reviewers have posted. There's a technique involved to keep it from all leaking out however.

Great stuff and very sturdy . Time will tell how UV resistant it is.

mmsj666: Most people would probably complain but I was full of happiness and joy. I ordered 1" but I actually received 1.25". I don't know if there are allowances to take into consideration when selecting size with this product but I double checked and even found it on the label. I won't be using this particular item on anything electrical. I like to use this stuff for other applications. Like softening tool handles or over sharp tool jaws so not to scratch chrome or plated finishes.

Matt Alexander: Honestly, this is the best heat shrink tubing I have ever used.
I have used many different brands, and this being an online purchase I wasn't sure what I would get.
This tubing shrunk well, I used a heat gun since this was large. I don't think a torch or lighter would have been easy for a large piece.
It is very robust! Not thin and flimsy.
If you need the finished product to be flexible this might be too firm, but wire this large isn't very flexible anyway.
Genuinely very pleased with this purchase!

BIG MACK WINOOSKI: Finally I found the best heat shrink tubing, with thick walls. I work on sewage pump stations and wire nuts are a joke in that environment. When I do a job I do not want to go back, with wire nuts that's not the case. I found 3:1 shrink tubing in the past but the walls were too thin and sometimes will rip, then I found this one. Also I have had my share of non insulated butt connectors and found the best one that has thick walls too and the brand is Airic that is sold on Amazon. Due to the electrical current going through the wires things will heat up, that's where this heat shrink tubing and Airic come to save the day.

J OsborneJ Osborne: 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...

Murrz Goldn: Fits larger and shrinks extra small. Great for most bigger electrical ends.
