I've been using this stuff to wire up several car projects. Including currently working on wiring a kit car from scratch. First off, amazon is the best shrink tube shipper I've found. Instead of a baggie with some shrink tube all folded over itself, or coiled into a box, they ship the stuff straight, in a box that fits the tube with no bends or kinks. These have been a pleasure to work with -- the glue is easy to activate when shrinking the tube. The sleeve seems to last well -- one of our race cars is about 3 seasons old now, and the shrink tubing looks as good as new. I have been using mostly the 1/4" tube -- it works nicely with #14-18 wire, and fits snugly over the blue crimps, but still shrinks fine over the red ones. For the yellow crimps and bigger wire, I have to go up to 3/8" (I wish that ancor made this in 5/16, because that does fit a bit nicer over the yellow crimps). I was using mostly the 4' sticks of the stuff...I just finished off two this weekend. The 4' sticks have a sticker flag at one end -- I'm not sure if that is inside or outside of the 4', but it takes up 2" of shrink tube at the end. The sticker is hard to get off, though if you remove the bulk of it, and the plastic outer layer, the rest of the sticker will come off easily under the heat gun while you shrink it onto the wires. Also, I discovered that this is cheaper in the 10x 1' pieces than as 1x 4' piece. i guess it's easier to ship that way. Anyways,this time I ordered a few of the 10x 1' sets, partially for slightly cheaper, and partially because I was able to add oneday shipping for it but couldn't for the 4' pieces.

This is high quality marine heat shrink. The price is a little steep, but you get what you pay for. The heat shrink that I received was black, not colored, if that matters to any potential customers. Marine heat shrink is different from regular heat shrink because it is adhesive lined, and offers better corrosion protection to wire splices. I purchased a boat last season that I rewired, and this stuff worked great! I recommend using this shrink wrap as opposed to electrical tape because shrink wrap is much more permanent, it makes for a very clean install, it won't come undone overtime, and it protects wire connections from moisture (and thus, corrosion) much better than electrical tape. I find that with an adequate splice and shrink wrap, solder is usually unnecessary in most automotive and marine applications. Hope this helps.

Ancor products are simply awesome. I do a lot of marine wiring in my line of work and on hobby projects and I refuse to use anything other than Ancor Adhesive lined heat shrink. I primarily use the 3/4" size for 2/0 battery cable and use smaller sizes as well. When you use this stuff, you can be confident that your connections will be waterproof. Make sure to research the size you need for your application, my below table is what I use (you may have different results) to pick sizes of heatshrink (Ancor heatshrink and Ancor wire): 1" - 2 - 4/0 AWG 3/4" - 6 - 2/0 AWG (Most versitile size for any battery cable work, and can sneak it onto 8 AWG at times) 1/2" - 8 - 4 AWG 3/8" - 12 - 8 AWG 1/4" - 16 - 10 AWG 3/16" - 20 - 14 AWG 1/8" - 26 - 18 AWG (Some 26 AWG Wires are too small for any heatshrink at times)

This heat shrink is excellent, but Amazon covers it in stickers that leave gummy residue all over it. They seem to inventory it without any kind of packaging, so they put all the inventory labels directly onto the product. For the 48" length I purchased, this resulted in about 40% of it being unusable. The Ancor heat shrink itself is some of the best dual wall adhesive lined heat shrink I have used. It's long lasting and resistant to heat and weather. I have used this heat shrink for battery cables in car engine bays and it works great. The half inch size is perfect for 4 gauge battery cable.

I have heard mixed reviews about shrink tube with the adhesive inside. Buying this product has completely opened my eyes!!!! I bought the 3/4 size and used it on some 2 gauge wire that had an outer jacket that was about 3/8 it shrunk very well and got very tight, after it shrinks fully you can see the adhesive ooze out the end a tiny bit. The only slight down side is any bumps or nicks on the inserted part will easily show through a light colored tubing. So for the perfectionist like me be sure to smooth your part before shrink tubing it. VERY happy with this product! I will definitely be buying more.

This heat shrink tubing has worked extremely well for me--it seems expensive (ok it IS expensive) when you look at the first time price but when you consider when you use this you will most likely not have to redo the work the cost goes down. I have used the heat shrink for repairs to two trucks, two trailers and a golf cart and the results are the same in each case. In south Texas we have not only the heat (ten days over 100 degrees and counting this month) but we also have heavy rain storms and not one repair has failed.
