Review: Good variety included - Good value
Review: Poor quality - The products advertised well not that good to be quite honest it seems more more stuff I’m buying off desertcart is becoming lesser and lesser quality

## Features

- High-Quality Tinned Copper Core- The heat shrinking connector copper core uses tinned copper, which is easier to flatten and grasp the wires, to enhance electrical conductivity.
- Polyolene Pipes- The connector shell is made of high-quality polyolefine and will not break the insulation layer when being pressed. They are resistant to corrosion and chemical erosion.
- Sufficient Hot Melt Adhesive- The connector contains sufficient hot melt adhesive, which generates more adhesive to wrap the wires during use, so the wires will not be easily detached.
- Easy to Use- Compared with other connectors, the heat shrinking connector has a larger selection of fitting tools and is easier to operate in the compressing process, suitable for DIY.

## Questions & Answers

**Q: why do you crimp the connector 3x?  One for each wire, what is the 3rd?**
A: I’m not sure why you have to crimp 3x’s unless their tool is designed that way? I only crimped  twice in my engine compartment of my pickup and have had no issues.

**Q: Will these work for 10/2 wire at 230V and 20 amps?**
A: You should be able to use on 230 volt 20 amp.  The yellow should handle 30 amp minimum. Usually if the wires fit in it. It will work

**Q: Do you have the Butt connectors that are 12-10 on one end and 16-14 on the other**
A: No, they are the same on each end. The colors indicate the size, as well they are labeled.

**Q: Can these be submerged? I want to use them for a bilge pump.**
A: Yes you can, the discription of the product says they are Marine Grade Waterproof Wire Connectors.

*by B***Z on 22 November 2021*

Al principio creí que no funcionaba el plástico termoretráctil porque lo estaba intentando encoger con un encendedor. Normalmente el tubín termoretráctil(heat shrink) sí se encoge con un encededor común, pero este es más grueso, entonces al hacerlo con encendedor no funciona, no se encoge y se empieza a derretir y quemar antes de encogerse. Pero ahora que compré una pistola de calor, funciona excelente. :D
