Whether you're an automotive technician, marine electrician, or serious DIYer tackling a home wiring project, you need insulation that stays put, seals out moisture, and won't crack under heat cycles. This 60mm 2:1 heat shrink tubing is built for exactly those situations.\u003c\/p\u003e\n    \u003cp\u003eEach order includes a continuous length of polyolefin heat shrink tubing in your chosen color and length (1 Meter \/ 2 Meter \/ 3 Meter \/ 4 Meter \/ 5 Meter). The tubing has a flat-width of 60mm — corresponding to an inner diameter of approximately 38mm before shrinking — and shrinks to roughly half that diameter (≈30mm) at a 2:1 ratio when heat is applied. Available in seven colors: Black, White, Red, Green, Yellow, Blue, and Transparent.\u003c\/p\u003e\n    \u003cp\u003eTypical use cases include insulating large wire harness bundles in automotive and marine wiring, protecting battery terminal connections and bus bars, covering pipe joints and conduit ends for light moisture protection, and color-coding multi-conductor cable assemblies in industrial or workshop settings.\u003c\/p\u003e\n  \u003c\/div\u003e\n\n  \u003cdiv class=\"hdiy-compat\"\u003e\n    \u003cspan class=\"hdiy-compat-icon\"\u003e🔌\u003c\/span\u003e\n    \u003cstrong\u003eCompatibility:\u003c\/strong\u003e Fits cables and bundles with an outer diameter up to approximately 38mm (≈1.5\").
