Frequently Asked Questions

Q: What sizes of heat shrink tubing are available in this listing?

A: This listing offers seven inner diameter options: 1.0mm, 1.5mm, 2.0mm, 2.5mm, 3.0mm, 3.5mm, and 4.0mm. Each roll is 5 meters long and black in color, so simply choose the size that best matches your wire or cable diameter.

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

A: A standard heat gun is recommended for the most even and consistent results. A hair dryer set to high heat can also work for smaller diameters. The tubing begins to shrink at +70°C and reaches full shrinkage at approximately +110°C.

Q: Is this heat shrink tubing safe for automotive and outdoor wiring?

A: Yes. The polyolefin material is flame retardant and UL approved, with an operating temperature range of -55°C to +125°C. It provides reliable insulation with a dielectric strength of 15 kV/mm, making it well-suited for automotive, marine, outdoor, and general electrical applications.

Q: How do I cut the heat shrink tubing to the right length?

A: Simply use a pair of scissors or a sharp utility knife to cut the tubing to your desired length before applying heat. Always slide the tubing over the wire or connection before shrinking, as it cannot be removed easily once applied.
