Frequently Asked Questions
Q: What heat source do I need to shrink the tubing?
A: Any consistent heat source works — a dedicated heat gun is ideal, but a hair dryer set to high heat or even a lighter held at a safe distance will activate the shrink. The polyolefin tubing shrinks quickly and evenly, so the process is fast and straightforward.
Q: What is the shrink ratio of this heat shrink tubing?
A: This set uses a standard 2:1 shrink ratio, meaning each tube will shrink to approximately half its original diameter when heat is applied. This makes it suitable for a wide range of wire gauges and connector sizes within each diameter range.
Q: Is this heat shrink tubing suitable for outdoor or automotive use?
A: Yes. The polyolefin material offers good resistance to moisture, abrasion, and general environmental exposure, making it a solid choice for automotive wiring harnesses, marine applications, and outdoor electrical connections.
Q: How many pieces and sizes are included in the set?
A: The kit contains 127 pieces total across 7 different diameters: 2.0mm, 2.5mm, 3.5mm, 5.0mm, 7.0mm, 10mm, and 13mm — all in black — so you always have the right size on hand for the job.
