White Heat Shrink Tubing 2:1 — Clean, Reliable Wire Insulation from 13mm to 80mm
Whether you're rewiring a trailer harness, repairing automotive cables, or tidying up a home electrical panel, finding the right white heat shrink tubing in the exact diameter you need can be frustrating. This product is designed for DIYers, electricians, and hobbyists who need a dependable, flame-retardant sleeve that delivers a clean white finish across a wide range of cable sizes.
Each piece is cut from flame-retardant polyolefin tubing with a 2:1 shrink ratio, meaning it shrinks to approximately half its listed diameter when heat is applied. Diameters range from 13mm (≈1/2") to 80mm (≈3-1/8"), and lengths are available from 0.1M (≈4") up to 5M (≈196") — so you only buy what you need. The white color makes it easy to label with a marker or match white-finished enclosures and conduit.
Typical applications include automotive wire harness sleeving, marine cable protection, electrical panel wire management, and DIY electronics repair. The larger diameter options (35mm–80mm) are especially useful for bundling multi-wire looms and cable management in workshops or equipment bays.
🔌
Compatibility: Suitable for copper, aluminum, and stranded wire. Works with standard heat guns (typically 120°C / 248°F for full shrink). Compatible with most automotive, marine, and general electrical wiring applications up to generally 600V.
⚠️
Size tip: Select a diameter 20–30% larger than your cable's outer diameter before shrinking. If you're unsure, contact us to confirm the right fit for your application.
✅ Key Features of These White Heat Shrink Tubes
-
🔥2:1 Shrink Ratio — Shrinks to approximately half its listed diameter, creating a firm, uniform sleeve around wire insulation and cable bundles of varying sizes.
-
🛡️Flame-Retardant Polyolefin — Self-extinguishing material meets standard electrical safety requirements, making it suitable for automotive wiring, panel work, and enclosed installations.
-
📏Wide Diameter Range (13–80mm) — Covers everything from individual wire terminals at 13mm (≈1/2") to large cable loom sleeving at 80mm (≈3-1/8"), reducing the need to stock multiple product lines.
-
✂️Cut-to-Length Flexibility — Available in lengths from 0.1M to 5M so you can order exactly what your project requires without waste — ideal for both spot repairs and full harness builds.
-
🎨Clean White Finish — The white color is easy to write on with a permanent marker for wire labeling, and blends naturally with white conduit, enclosures, and appliance wiring.
-
💧Moisture & Abrasion Resistance — Polyolefin construction provides a protective barrier against moisture ingress and light abrasion, extending the service life of wire insulation in demanding environments.

❓ Frequently Asked Questions
How do I choose the right diameter for my wire or cable?
Measure the outer diameter of the cable or bundle you need to cover, then select a heat shrink size that is generally 20–30% larger than that measurement before shrinking. For example, if your cable is 10mm in diameter, a 13mm (≈1/2") tube will typically provide a snug fit after shrinking. The 2:1 shrink ratio means the tubing will shrink to approximately half its listed diameter.
What shrink temperature is required?
Polyolefin 2:1 heat shrink tubing generally begins to shrink at around 70°C (158°F) and achieves full shrinkage at approximately 120°C (248°F). A heat gun is the recommended tool; an open flame can be used carefully but may cause uneven shrinkage or scorching.
Is this heat shrink tubing suitable for outdoor use?
Standard polyolefin heat shrink tubing provides basic moisture resistance and is generally suitable for light outdoor applications. For prolonged UV exposure or submersion, an adhesive-lined or dual-wall variant is typically recommended for a fully waterproof seal.
What is the voltage rating of this tubing?
Polyolefin 2:1 heat shrink tubing is generally rated for up to 600V in standard electrical applications. For high-voltage or industrial environments, please contact us to confirm suitability for your specific use case.
Is this tubing flame-retardant?
Yes, this tubing is made from flame-retardant polyolefin material, which means it will self-extinguish when the heat source is removed. It meets the requirements of most standard electrical safety applications.
Can I use this for bundling multiple wires together?
Absolutely. The larger diameter options (35mm–80mm) are well-suited for bundling and sleeving wire harnesses, cable looms, or grouped conduit runs. Measure the total outer diameter of the bundle and select a size approximately 20–30% larger for a clean, secure fit.
How do I cut the tubing to length?
Standard scissors or a utility knife work well for cutting polyolefin heat shrink tubing before shrinking. For clean, straight cuts on larger diameters, a sharp pair of shears or a rotary cutter is recommended. Always cut before applying heat.
