XHF UL Listed 1/2 Inch (13mm) 3:1 Waterproof Heat Shrink Tubing Marine Grade Wire Cable Adhesive Lined Tube Insulation Seal Against Moisture Corrosion and Air Leakage, 4 Ft Black

Shrimp down perfectly on a shovel handle I will be ordering more to recover all of my hand, tools. Can’t speak to how long it will last, but it seems to be very sturdy and thick. I think it will last a long time and serve me well.

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

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.

Worked well for my project.

I purchased the XHF UL Listed 1 Inch (25mm) 3:1 Waterproof Heat Shrink Tubing to be used on a submersible pump wire. I used it with a 14 gauge 3 conductor royal type wire. I had already sealed each wire connection (3) with waterproof heat shrink tubing with adhesive, but since the wire will be going in the water, I wanted to insulate all the connections and the wire itself, so I bought the 1" size of the XHF 3:1 waterproof heat shrink tubing so as to slide over all three waterproof connections. It concerned me that the XHF heat shrink tubing would not shrink enough to adhere to the 14 ga. wire itself.....but it did! The XHF heat shrink tubing did a marvelous job of shrinking around the three already insulated connections and then it shrank enough to adhere to the cable insulation itself, oozing out the glue on the ends to confirm it adhered! I am impressed! The XHF heat shrink tubing is not the normal thin heat shrink tubing you use for smaller wires, but is adequately thick too! I was impressed with the thickness and durability of this heat shrink tubing, even once it shrank. It was easy to use, as I just cut off the length I needed to cover the exposed 3 wire connections and and extra couple of inches on each end, to cover the cable itself. I then used a standard heat gun/paint stripper to heat the shrink tubing. It did as advertised.....shrunk enough to provide waterproof insulation with an adhesive. It didn't come with instructions, but if you heat from the center of the tubing (keeping the heat gun moving continuously) outward to each end, you should get the same satisfactory results as I got. I am pleased with this purchase and feel confident that it will provide the results (waterproof and durable) that I was looking for! Yes, I would purchase again!

I purchased the heat shrink tubing for a project I was working on, the heat shrink performed exceptionally well. It was easy to use and looked great when I was finished. The 1 1/2 inch heat shrink fit over the 1 1/4 inch cylinder that had a smaller 3/4 inch lower portion. The heat shrink not only reduced to fit the 1/1/4" section as expected but also shrunk down to tightly fit around the 3/4" lower portion of the cylinder. It shrunk down uniformly over both parts of the cylinder using my heat gun. I would definitely buy this again.

My True treadmill front roller is small diameter (1.75") and had a plastic sleeve on it to increase friction for advancing the belt. In time, this sleeve split and bunched up causing an annoying sound when using the treadmill. The fix for this is to remove the remnant plastic sleeve, clean the roller and cover it with a piece of shrink tube. The 2" variety of XHF tube was selected and delivered in one day by Amazon. A heat gun was sufficient to shrink the tube onto the treadmill roller, although not without a few small ripples in the finished job. After reassembly with the shrink tube covered roller the treadmill is operating perfectly and much quieter than before. The XHF shrink tube worked well for this application and I am very satisfied with the result at low cost. The small ripples noted in the result appear to have no effect on treadmill operation but it would be a neater job without them. Here are some ideas that might help reduce the likelihood of a wrinkle: the shrink tube is delivered flat - introducing creases midway between the existing creases might help the shrink tube fit more uniformly around the roller prior to shrinkage; shrink the tube a little bit at a time over its entire length rather starting in the middle as I did and shrinking that section down tight before moving toward the ends. Edit 1/11/2020 The treadmill developed an annoying sticky-flappy sound again after nine months of quiet. The sleeve previously applied on the treadmill roller with the heat shrink tube was loose and would easily slide up and down the roller - a snug fit still, but no longer fixed tightly to the roller (so much for the ‘adhesive’ properties this heat shrink tubing is supposed to have). This small space between tube and roller must be the cause of the noise. (I missed a trick here: I should have tried to affix the sleeve again by applying heat). I tried unsuccessfully to use shrink tube of initial diameter 1.75 but could not get it on the roller more than a few inches before friction got too great to pull it on further. So back to the original 2” shrink tube. Luckily the length of the roller was less than 24" so I had plenty left over from the initial four foot section to make another roller cover. I sanded the surface of the treadmill roller to make it rougher and cleaned it well with isopropyl alcohol. I tried flattening the tube to set a crease halfway from the initial crease in the using piles of books; that didn't really do much to add a new permanent crease. I did change my shrinking technique a little: starting at one end I concentrated on first shrinking the portions of tube that stuck out most from the roller (caused by the crease from the flattened tubing). After shrinking those portions on opposite sides of the roller, I applied heat to the area in between. By this method I was able to shrink the tube on the roller with practically no remaining ripples or bumps; a big improvement over the first attempt. I used a Dewalt heat gun at 400 degrees F for shrinking and the process took about twenty minutes. This sort of tubing is supposed to shrink at around 210 F but it would be an incredibly slow process. I toyed with the idea of ‘curing’ the tubing even more in my kitchen over but caution won out: one end of the roller has a ridged end cap pressed on for the drive belt pulley and this cap appeared to be made from plastic. I would be majorly sad if the oven curing melted or deformed that cap. So that should be it. Hopefully I won’t be writing about attempt number three in the near future.

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.

Wrong size but Im sure its good stuff. Ad has incorrect size. Its about 2" wide not 1.25 inch.

Corresponds to the description

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