Dual Wall Adhesive Marine Heat Shrink - 10 Ft Roll - 3/8 Inch Diameter - Black

Should be Zero Stars. Came packaged so tightly, that the adhesive had already seized itself, and only the first couple inches was usable, but only after manipulating it apart with a knife and screwdriver. Of course, this didn't come to light until I was doing a submersible pump refurb and needed a couple feet of 3/4" shrink. Totally unusable .. wound into a tight little roll with two tiny voids at the edges. So I had to weave four layers of black gorilla tape on this splice, as I had ordered this "premium" product to replenish my 3/4" stock of shrink. Big mistake. Zero Stars.

Very solid product to create a professional result. They have added glue so when you shrink the tube onto a cable (as an example) you will get a perfect fitting. The product comes in a nice box with the different sizes sorted. The tubes are 90mm long (3.54 inch) so I could use one tube for two fittings. I used it for my RG 8x cable with PL259 connector and UG176 adapter.

The assortment and color selection was good for advertising an actual product was bad . If you look at the general size swordfish that’s being advertised for 3 to 1 ratio the smallest piece that I should’ve had would’ve been roughly a quarter ranch but I have 266 pieces of stuff that if I was in a telecommunication business I could probably use that for 30 awg terminals . Add where is the glue I tried 13 different attempts for sit there and see if any sealant came out of anything and it was weak at best

I ordered the 25' roll because I was tired of only getting a couple of 3" tubes of the 1/2" shrink tubing in a kit. I love having the control of cutting the lengths needed & reducing waste. IF, & that's a big IF, IF there's anything I didn't like, it's miniscule & requires no mention. I will DEFINITELY be ordering more rolls of various sizes from this seller.If you're looking for marine grade shrink tubing, I highly recommend this. It shrunk perfectly & should help to keep my LED installations nice & moisture free.The only thing I don't like concerns Amazon & their codes. I would prefer to stick with certain sellers for specific products (this shrink tubing for example). This way, I can contact them directly for a resupply & deal with them EXCLUSIVELY. But, I'll just order from my previously ordered list to stick with these sellers.

Product works great. It is just as described, and got it in the promised time. Vendor even sent a follow up message to make sure everything was working fine. An unexpected but welcomed gesture. That is good customer care! So here my review.You have to practice a little to apply well. In particular, what worked best for me is to start on one end and make my way to the other, or start in the center. On my first application I just tried to apply heat evenly and the ends closed sooner which resulted in a little air trapped in the middle. So just take the tipn'tAfter a couple of experiments, this is working like a charm! Love it! Rescued a few iphone charging cables already, and a 30pin to lighting converter which is pretty expensive.I only wish the box came with more of the sizes I use most. It has dozens of the smaller diameters that I might never use, and just a few of the mid sizes which are the ones I really need.

I used the 3/4" dual wall material to put over my arc welding cable leads, that had insulation starting to show wear and cracks. The material was coiled tightly, so was flat and stuck together some, which prevented the welding cable to be pushed through it. I tried a wire fish tape, but it was too flexible to push through. I then took a piece of 3/8" rebar I had and made one end more tapered and pushed it through the wrap slowly while squeezing the wrap to unflatten it. I then taped the arc welder wire to the rebar and pulled the wire back through. It shrunk done tight on to the wire and ends when heated with a heat gun. It worked great and should give my arc welder wire another 50 years of service.

Make note that this is adhesive heat shrink rather than normal heat shrink. That means it's going to hold in place far better than normal heat shrink that can get stretched over time and sometimes even start to slide on the wires.These pieces worked PERFECTLY for some custom headphone cables I was creating.Protip: If you're making a custom set of headphone cables and need to make a Y split, measure where you want your split to be, wrap it about 5 times with electrical tape, then slide a piece of this heat shrink (about a half an inch longer than the width of the tape) over the top and give it some heat. The heat shrink will shrink (of course) a little, but should make a beautiful looking Y split with nothing more than electrical tape and heat shrink.

I completely refreshed a small fishing boat and trailer adding electricity to the boat like running lights, bilge pump, trolling motor, and safety lights. To do that, I ran tons of wiring from one end to the other. Needless to say, I need to make sure that the wiring was not only water proof, but that it will not chafe or rub on metal surfaces. I added this tubing to all my wiring and after 7 years of use, including running it in the frame of the trailer (my most recent addition), the tubbing has held up amazingly! Supper easy to sue, just like other shrink tubing, BUT, since it is dual wall, when you heat and shrink it, it also melts the waterproofing 'stuff' further enhancing the water proofing capacities! I love this stuff and have ordered other sizes since!
