This ensures a snug, secure fit around most common wire gauges within the 3mm–6mm size range.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What tool do I use to shrink the tubing?\u003c\/h4\u003e\n\u003cp\u003eA: A standard heat gun is the most recommended tool for even, controlled shrinking. In a pinch, a lighter or match can be used carefully — keep the flame moving to avoid scorching the tubing. Avoid direct sustained flame contact.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Are all four sizes included in one purchase?\u003c\/h4\u003e\n\u003cp\u003eA: Yes! Each pack contains four separate 1-metre lengths — one each of 3mm, 4mm, 5mm, and 6mm black PE heat shrink tubing — giving you a total of 4 metres across the four diameters.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Can this heat shrink tubing be used in automotive wiring?\u003c\/h4\u003e\n\u003cp\u003eA: Absolutely.
