ELECFUN Versatile Heat Shrink Tubing

Looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief?

ELECFUN heat shrink tubing is a great solution, which used in automotive, marine electronics, DIY, and home wiring projects. Such as: 1.Electrical insulation (wire repairs, insulating terminals wires, protecting charging cables, car battery cable ends) 2. Environmental seal to protect from moisture, UV, fuel, and chemicals 3. Strain relief for electrical terminals 4. Grouping loose wires (usually in wire end) 5. Creating thermal insulation for heat-sensitive components 6. Protecting surfaces against abrasion, peeling, fuel resistant, and denting...

3:1 Shrink Ratio & Dual Wall

When heating with a heat gun or other heater, the tubing will recover to 1/3 of its original diameter, which makes it possible to repair most damaged cable jackets without removing connectors. The dual wall tube provides better rigidity and abrasion. The double thick polyolefin tubing secures durable safe for projects.

Heat Activated Adhesive Lined

Our waterproof tubing has an internal adhesive layer. When heating, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive becomes visible at the end of the heated tubing. When cooled down, it forms a rigid seal. Heat-activated glue strongly adheres to wires, terminals, or any other surfaces.

Works as advertised. Quick delivery. I used them to slide onto my rifle cleaning rods. This prevents the metal ( Aluminum) edges of the rods from contacting the edges of the barrel or revolver bullet cyclinder

Met my needs with good shrinkage on a car antenna stem. This will last me a long time and I really like the size variety.

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.

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

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

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.

Love the two colors. Can then recognize instantly. Wiring anything that polarity is a must have. The coverage is excellent too. Just seal quick and move on to the next one. By the time you read this, you are already packing your gear.
