Frequently Asked Questions

Q: What sizes of heat shrink tubing are included in this kit?

A: This heat shrink tubing kit includes five sizes: 1mm, 1.5mm, 2.5mm, 3mm, and 4mm supplied internal diameter. Each size comes as a 126cm length, giving you a total of five separate pieces — one per size — in the set.

Q: What tool do I need to shrink this tubing?

A: A standard heat gun is the most reliable tool for shrinking this tubing evenly. Shrinkage begins at +70°C and reaches full shrinkage at around +110°C. You can also use a lighter or soldering iron in a pinch, though a heat gun provides the most consistent results.

Q: Is this heat shrink tubing safe for electrical wiring projects?

A: Yes. This tubing is made from flame-retardant polyolefin, is UL Approved, and has a dielectric strength of 15 kV/mm, making it well-suited for insulating and protecting wire connections, terminals, and plugs in both hobby and general electrical applications.

Q: Can I use this for RC (remote control) battery connectors like T-plugs and banana plugs?

A: Absolutely. The kit is specifically compatible with T-plugs, banana plugs, and power plugs, making it a popular choice for RC drone, car, and aircraft hobbyists who need to insulate solder joints on battery connectors.
