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 tubing is quite a bit thicker than I expected and does a fantastic job. I normally can easily "snip" similar tubing with regular scissors. This stuff was significantly tougher! The 3:1 shrink ratio allowed me to slide it over connectors. It fit tightly around the wire with great adhesion after heating. It remained quite clear. I plan to buy more of this.

1/2 inch 3:1 Black...First rate product, thick walled and durable. I used on 8 awg wire and it shrunk tightly against both the wire and terminal fitting with glue oozing out of both ends as intended. It's nice to see such a quality product available.

Nice and thick. Great quality! Glad I ordered more than I need for the current project so I’ll have more when needed in the future.

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.

Works as it should. Shrinks perfectly and premium quality.

I’ve used many brands of heat shrink with my electrical hobbies and this is by far some of the best stuff I’ve used. I’ve used plenty of “high end” shrink tubing in my day.By far the best. Tough as nails. Nice and thick and strong. I’ve mainly been using for 2 AWG wire and it’s great. I used a temperature controlled heat shrink gun that has various sized nozzles for precision work. For me I have found 650F to be the sweet spot for working with this stuff. Shrinks slowly but not too slow at this temp. You can see the tubing start to get of a glossy sheen when it’s done (others do this too). You get a good amount of glue for a waterproof seal though I would never use this is a submerged environment personally.I sometimes double up and use two cuts for an even tougher protection. However this does make it much thicker if space is an issue. Honestly it’s overkill but I sometimes do it.Buy with confidence this stuff is awesome.

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 1/11/2020The 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.
