Review: Great product at a great price. Work well. - Great product and works well. When the heat gun I got was actually working without smoking it wrapped my wires perfectly. The only problem I had is my wires are the same I am shrink wrapping and there are only so many of those for those wires in this kit. The rest are either too small or too large. But maybe who knows in the future. These different sizes will come in handy.
Review: Better quality than most. - Good quality tubes with glue inside. Nice selection of sizes. Wish they were a bit longer, but you can use two and overlap them for a great seal.

## Questions & Answers

**Q: Is the diameter on each tube the original size (pre-shrinking)?**
A: Yes.Size is before shrinking,3/32 shrinks to 0.8mm. 1/8 shrinks to 1.1mm. 3/16 shrinks to 1.6mm. 1/4 shrinks to 2.1mm. 3/8 shrinks to 3.2mm. 1/2 shrinks to 4.2mm. 3/4 shrinks to 6.0mm

**Q: Can this be used to join two tubes together? Does the glue just seal the ends or the entire tube?**
A: If the tubes and the heat shrink tubes fit snugly after heating them I'm sure it would work well. This is very durable heat shrink, thicker than most. Keep in mind also, it's 3:1 shrink. Glue throughout the tubing.

**Q: What is the max temperature on these heat shrink tubes? Can I put it in the car engine bay?**
A: Operating temperature: -55℃～125℃.They can be used in an engine bay.

**Q: where is this made ?**
A: Our heat shrink tubing kits are produced in China,but I can say after using these on a number of projects and boat rewiring they don't leak or seem to be affected by oil/gas/saltwater,and they've held up over time which is all that matters.

*by A***V on January 31, 2026*

This is an absolute must if you do any sort of wiring. These work great. Easy to shrink wrap. I love the glue that is internal and actually seals everything up from the elements. Definitely a must-have for any mechanic. Definitely would recommend.
