ELECFUN Waterproof Heat Shrink Tubing Kit 365 pcs, 3:1 Dual Wall Tube - Adhesive Lined Heatshrink for Wires - Marine Grade and Industrial Shrinkable Wiring Wrap Fully Insulation Black/Red, 7 Sizes

Bought this kit went to rewired my boat trailer. Everything worked the way it should. It was perfect.

I like the 3 to 1 shrink ratio and the assorted hobby sizes and 2 lengths. These seem to shrink quicker and tighter, needing less heat to get snug than regular 2 to 1. It states for industrial and for marine applications, but I just want a good tight fit to cover red and black bare wire and connections. These are working great and I will purchase more when needed. I would recommend this set for positive/negative color wire and connections. Other sets will have other colors if needed.

I like the shrinks and do a good job.

Worked great, just wish they were about 1/4 inch longer so they go over butt connectors with a little extra length to go up the wire itself

Yes, it does what is stated in the description. I have ordered this particular brand from this particular vendor on at least 3-4-occasions, maybe 1/2-dozen. It is made of surprisingly good quality adhesives and polymers (and whatever else those mad lad chemists come up with, I’ll stick to RF engineering myself). The 3:1 heat shrink tubing walls are thick (thicker than SOME brands I have tried but not all) and the adhesive is surprisingly, well, adhesive. Once the thick adhesive lines tubing cools about 20-30-degrees C, it starts to set, quickly. Once it sets it holds/grips with reassuring authority although you can gently reheat the tubing and adjust (slightly) its position. I use a couple of boxes (of various sizes) of 3:1 adhesive heat shrink tubing every couple of months and this specific kit is one I often reorder. The price is always fair and the performance is just what you would expect from adhesive 3:1 heat shrink tubing and is easy to cut and use.

Lots of sizes and a large quantity of the smaller sizes that are frequently used. Cut into 1 1/2" sections, perfect for splicing wires. Easily shrinks with a lighter and is waterproof when done. The glue also acts as a strain relief to help keep crimped joints intact. I use these on uninsulated butt connectors and have never had a problem.

Work great, use them all the time.

Shrinks well. Adhesive visible when fully shrunk. Good.

Bon produit Qualité/prix

Very happy with the purchase they are amazing. They work really well. They are good quality.

Satisfactory and adequate usage. Thank you.

Needed something for emergency splices at work, the multi pack has every size I could need and melts super easy when heated. I haven't had a problem and some of the repairs have been left for months outside in the elements. Great for the price

Heat shrink tubing works great. Storage case can sometimes have the smaller pieces end up in the wrong compartments, but I purchased for the heat shrink tubing and it's excellent! Have used this tubing in 30+ projects without a single issue
