Heat Shrink Tubing Roll — Reliable Wire Insulation for Every Project
Whether you're rewiring a car stereo, repairing frayed cables, or organizing a control panel, exposed wire ends and loose connections are a constant hazard. DIYers, electricians, and hobbyists all face the same problem: finding heat shrink tubing that comes in the right diameter, the right color, and enough length to last through multiple jobs without running out mid-project.
Each roll of this heat shrink tubing is sold as a single continuous roll — available in lengths of 100m (≈328 ft) or 200m (≈656 ft) per roll, and in diameters from 1mm (≈3/64") up to 10mm (≈3/8"). The tubing is made from polyolefin, a material known for its flexibility, consistent wall thickness, and clean shrink performance. Seven color options — Black, White, Red, Green, Blue, Transparent, and Yellow — make color-coded wiring straightforward.
This heat shrink tubing roll is well suited for automotive wiring harness repair, electronics prototyping and PCB wire management, home electrical projects, and marine or outdoor cable bundling where a clean, insulated finish is needed. The generous roll length makes it practical for workshops, service vans, and anyone who works with wire regularly.
🔌
Compatibility: Fits standard wire gauges AWG 26 down to AWG 6 depending on diameter selected. Works with copper, aluminum, and stranded wire. Suitable for 12V automotive, low-voltage electronics, and general-purpose electrical applications. Verify your wire OD against the expanded diameter before ordering.
✅ Key Features of These Heat Shrink Tubing Rolls
-
📏Wide Diameter Range — Available in 12 sizes from 1mm to 10mm, covering thin signal wires through heavier cable bundles for automotive and electronics heat shrink applications.
-
🎨7 Color Options — Black, White, Red, Green, Blue, Transparent, and Yellow allow color-coded wire identification in wiring harnesses, control panels, and DIY electrical projects.
-
🔥Clean 2:1 Shrink Ratio — Polyolefin construction delivers a consistent, even shrink that conforms tightly to irregular shapes without cracking or leaving gaps around connectors.
-
📦Bulk Roll Format — 100m or 200m per roll means you cut exactly what you need for each job, reducing waste and keeping your workshop stocked for ongoing wire insulation and cable repair work.
-
⚡Electrical Insulation Performance — Polyolefin tubing provides solid dielectric insulation, protecting connections from short circuits, abrasion, and moisture ingress in low-voltage wiring applications.
-
✂️Easy to Cut and Apply — Cuts cleanly with scissors or a utility knife; shrinks with a standard heat gun, soldering iron tip, or carefully applied flame. No special tools required for most applications.

Size Check Reminder: Always measure the outer diameter of your wire or connector before selecting a tubing size. The expanded diameter listed is the size before heat is applied. After shrinking, the tubing will recover to approximately half that diameter.
❓ Frequently Asked Questions
How do I choose the right diameter heat shrink tubing?
Select a diameter that is slightly larger than the widest part of the object you need to cover before shrinking. For example, if your wire bundle measures 2mm across, choose the 2.5mm or 3mm tubing. After heat is applied, the tubing typically shrinks to roughly half its original diameter (2:1 ratio), so the recovered size should be smaller than your component. When in doubt, size up — you can always apply more heat, but you cannot reverse over-shrinking.
What shrink ratio does this tubing use?
This heat shrink tubing generally uses a 2:1 shrink ratio, meaning it shrinks to approximately half its expanded diameter when heat is applied. For example, the 4mm tubing will typically recover to around 2mm. Exact recovered diameter may vary slightly by color and batch — contact us to confirm if tight tolerances are required.
Can this heat shrink tubing be used outdoors?
This tubing is generally suitable for light outdoor use where it will not be continuously submerged or exposed to prolonged UV radiation. For harsh outdoor environments — such as marine wiring, underground burial, or direct sunlight exposure — we recommend a dual-wall adhesive-lined heat shrink tubing for added moisture and UV resistance. Contact us to confirm suitability for your specific application.
What temperature is needed to shrink this tubing?
This tubing typically begins to shrink at around 70–90°C (158–194°F) and fully recovers at approximately 120°C (248°F). A standard heat gun set to low or medium is the recommended tool. A lighter or match can work in a pinch but may cause uneven shrinkage or scorching — use with caution.
Is this tubing compatible with standard wire gauges?
Yes. The diameter range of 1mm–10mm covers most common wire gauges used in automotive, electronics, and home wiring projects. As a general guide: 1–2mm suits thin signal wires (AWG 26–20), 3–5mm suits medium wires (AWG 18–14), and 6–10mm suits heavier cables or small wire bundles. Always measure your wire or connector before selecting a size.
How much tubing do I get per roll, and can I cut it to length?
Each roll contains either 100m (≈328 ft) or 200m (≈656 ft) of tubing depending on the variant selected. The tubing can be cut to any length with standard scissors or a utility knife before or after shrinking. Buying by the roll is significantly more economical than pre-cut pieces for ongoing projects.
Does the color affect the electrical or thermal performance?
In most cases, color is purely cosmetic and does not affect the electrical insulation or shrink performance of the tubing. All color variants in this listing are made from the same base polyolefin material. Color-coding is commonly used in wiring harnesses to identify circuits — for example, red for positive, black for negative, and green or yellow for ground in some standards.
