## Description

Are you looking to fix a damaged wire, seal out moisture, or provide enhanced strain relief ? Wirefy adhesive heat shrink tubing is an easy to use solution for insulating and protecting wires, cables, connections and components. It can be used in a variety of of applications: marine and automotive wiring, outdoor and home repairs, RC hobbies, or giving your phone charging cable a second life.This is a moderately stiff dual wall heat shrink tubing with the internal adhesive layer. It is 4:1 shrink ratio tubing, which allows it to be used in significantly more applications compared to 2:1 and 3:1 shrink ratio tubing. When heat is applied, shrink tubing recovers and the internal adhesive layer melts. A small fillet of clear adhesive (about 1 mm wide) becomes visible at the end of the heated tubing. When cooled down it forms a rigid seal. Heat activated glue strongly adheres to wires or any other surface. This heat shrink tubing assortment comes organized in individual compartments to keep things neat and tidy.This electrical shrink tubing is UL listed and compliant with all relevant electrical standards: SGS, RoHS, Reach, and ISO9001.

Review: Awesome product - Big fan of wirefy products. Affordable but good quality
Review: I ordered this product after research and reviews. Was not disappointed it’s really great stuff I’m a newbie in doing van electrics and solar install and wanted the wiring to be safely protected some may think it’s overboard but I wanted good coverage and sealing. This 4:1 heat shrink was so easy to use I did procrastinate on what size trying to work that out initially but once I got going it was fine I used a heat gun and then welding gloves to protect my hands. Anyway the result was just what I was hoping for and has given my cables of various thickness a really good wrap. Swift delivery and would have no hesitation in re ordering from this seller, many thanks.

## Questions & Answers

**Q: Are the dimensions listed the recovered or unrecovered size?**
A: Hi,

The 4:1 shrink ratio simply means that it recovers to 1/4 of its original diameter.

I hope this helps! You can contact us directly if you need more info.

**Q: Can it be used with self regulating heat cable**
A: Hi,

We do not recommend it because it will generally be kept at a higher temperature, up to 120℃, occasionally as high as 175℃.

**Q: Can this be used to cover banana plugs in use with speaker wire?**
A: Thank you for your question. Yes, it can be used to cover banana plugs in use with speaker wire.

**Q: Can these be used to reinforce the wire leading to earbuds? The rubber has ripped exposing a small window of the wires.**
A: You could if you are very careful as the heat needed to use for these could very easily melt the wires for your ear buds. You may be better off using liquid tape.

Queste fascette termorestringenti sono veramente OTTIME. Valgono ogni centesimo. Robuste, ottimo assortimento, si restringono veramente sino a 4 volte. Prodotto davvero di qualità. L'unico appunto che potrei avanzare riguarda la scatola di plastica in cui sono contenute: Le cerniere posteriori non tengono e la scatola tende ad aprirsi. Un elastico ed il problema è risolto. Soddisfattissimo.
