80mm PVC Heat Shrink Tubing — Reliable Insulation for Battery Packs and Cable Bundles

If you've ever finished building a battery pack or wiring harness only to leave it exposed and vulnerable, you know the frustration of sourcing the right sleeve after the fact. DIYers, EV builders, RC hobbyists, and electricians working with large-format battery assemblies need a wide-diameter heat shrink solution that goes on cleanly, shrinks evenly, and stays put. This 80mm PVC heat shrink tubing is stocked specifically for those jobs.

Each order includes a continuous length of PVC heat shrink tubing with an expanded inner diameter of 80mm (≈3.15"). Available in lengths from 1 Meter (≈39.4") up to 30 Meters (≈98.4 ft), and in seven colors — Black, White, Green, Blue, Red, Transparent, and Fruit Green. The tubing is supplied in flat, rolled form and expands to its full 80mm diameter when slid over your workpiece. Upon applying heat, it shrinks to conform tightly around the surface.

Typical use cases include wrapping 18650 or 26650 lithium battery packs for e-bikes and power tools, sleeving thick cable bundles in automotive and marine wiring projects, and color-coding wire harnesses in control panels or DIY electronics builds where clear identification matters.

🔌 Compatibility Note: Designed for battery packs, cable bundles, and wire harnesses with an outer diameter that fits within 80mm (≈3.15"). Verify your bundle diameter before ordering. For smaller diameters, see our other heat shrink tubing sizes.

✅ Key Features of These 80mm PVC Heat Shrink Tubes

📏Wide 80mm Diameter — Expanded inner diameter of 80mm (≈3.15") accommodates large battery packs, thick cable bundles, and multi-conductor wire harnesses that standard heat shrink tubing cannot cover.
🎨7 Color Options — Choose from Black, White, Green, Blue, Red, Transparent, and Fruit Green for easy circuit identification, color-coded battery wrapping, or a clean finished appearance.
📦Flexible Length Selection — Available in 1m, 3m, 5m, 10m, 20m, and 30m cuts so you can order exactly what your project requires — from a single battery sleeve to a bulk wiring job.
🔥Even Heat Shrink Performance — PVC construction responds uniformly to heat gun application, conforming tightly around cylindrical and irregular surfaces without bubbling or splitting when heated correctly.
✂️Easy to Cut and Fit — Cuts cleanly with scissors or a utility knife before shrinking; no fraying or unraveling. Ideal for custom-length battery pack insulation sleeves and cable wrap projects.
🛡️Electrical Insulation and Abrasion Protection — Provides a layer of electrical insulation and surface protection against abrasion, dust, and light moisture — suitable for indoor wiring and light-duty outdoor cable management.

❓ Frequently Asked Questions

How do I choose the right length of heat shrink tubing?

Measure the total length of the cable run or battery pack you need to cover, then add at least 10–15% extra to account for trimming and overlap. For example, a 90cm (≈35.4") battery pack would typically need a 1 Meter length. For longer wiring harnesses or bulk projects, the 5m, 10m, or 20m options offer better value per meter.

What diameter does this tubing shrink down to?

This tubing has a supplied (expanded) inner diameter of approximately 80mm (≈3.15"). PVC heat shrink tubing generally has a shrink ratio of around 2:1, meaning it will typically shrink down to roughly 40mm (≈1.57") in diameter when heat is applied. We recommend confirming the fit against your specific battery or cable bundle before ordering.

How much heat is needed to shrink this tubing?

PVC heat shrink tubing generally activates at temperatures around 70–90°C (158–194°F). A heat gun set to low or medium is the recommended tool. Avoid open flames, as uneven heat can cause bubbling or uneven shrinkage. Move the heat gun steadily along the length of the tubing for an even result.

Is this tubing suitable for outdoor or waterproof applications?

Standard PVC heat shrink tubing provides basic moisture resistance and is suitable for indoor and light-duty outdoor use. It is not a waterproof seal. For fully waterproof applications, consider dual-wall adhesive-lined heat shrink tubing instead. If you need outdoor-rated sleeving, contact us for guidance.

What types of batteries or cables is this compatible with?

The 80mm expanded diameter is well-suited for large-format battery packs (such as 18650 or 26650 cell packs assembled into e-bike or power tool configurations), thick cable bundles, wire harnesses, and conduit wrapping. It is generally compatible with any cylindrical or bundled object that fits within the 80mm opening before shrinking.

Can I cut this tubing to a custom length?

Yes. PVC heat shrink tubing cuts cleanly with standard scissors or a utility knife. Cut to your desired length before applying heat. The tubing will not fray or unravel after cutting, making it straightforward to prepare multiple pieces from a single roll for batch battery pack insulation work.

Which color should I choose for my project?

Color choice is typically based on identification or aesthetics. Black is the most common for general wiring and battery packs. Transparent allows you to see the underlying components — useful for inspection or display builds. Colored options (Red, Blue, Green, White, Fruit Green) are useful for color-coding different circuits or battery configurations in multi-pack assemblies.
