Large Diameter PVC Heat Shrink Tubing — Reliable Insulation & Protection for Battery Packs and Wiring

If you've ever struggled to find heat shrink tubing wide enough to cover a battery pack, a thick cable bundle, or a large-diameter wire harness, you know how frustrating the search can be. This large diameter PVC heat shrink tubing is designed for DIY builders, EV hobbyists, electricians, and makers who need dependable insulation and a clean finish on oversized applications — without hunting through specialty suppliers.

Each roll is made from flexible PVC material and is available in outer widths from 70mm (≈2.76") to 103mm (≈4.06"), with inner diameters ranging from Ø44mm (≈1.73") to Ø65mm (≈2.56"). Lengths are available in 1M (≈39.4"), 2M (≈78.7"), 5M (≈196.9"), and 10M (≈393.7") rolls. Ten colors are offered — Black, White, Green, Yellow, Blue, Red, Clear, Fruit Green, Silver Grey, and Purple — so you can color-code your builds or match your project's aesthetic.

Common use cases include wrapping 18650 and 21700 lithium battery packs for e-bikes and power tools, sleeving thick cable looms in automotive and marine wiring projects, and protecting copper bus bars or terminal connections in DIY power storage systems. The wide size range makes this large diameter heat shrink tubing a go-to solution for any project where standard narrow tubing simply won't fit.

ℹ️ Compatibility Note: Before ordering, measure the outer diameter of your battery pack, cable bundle, or component. Select a tubing width whose inner diameter (Ø) is slightly larger than your measured dimension. This tubing typically shrinks to approximately 50% of its supplied inner diameter when heat is applied.

✅ Key Features of These Large Diameter PVC Heat Shrink Tubes

📏Wide Size Range — Nine width options from 70mm (Ø44mm) to 103mm (Ø65mm) cover everything from individual 18650 cells to large multi-cell battery packs and thick cable bundles.
🎨10 Color Options — Choose from Black, White, Green, Yellow, Blue, Red, Clear, Fruit Green, Silver Grey, and Purple to color-code circuits, match your build, or improve visual identification at a glance.
🔥Even Heat Shrink Performance — PVC material responds uniformly to a standard heat gun, conforming snugly around irregular shapes and providing a smooth, wrinkle-free finish on battery wraps and wire sleeves.
⚡Electrical Insulation — Provides a protective insulating layer over exposed conductors, terminals, and solder joints, reducing the risk of short circuits in battery pack builds and wiring harnesses.
✂️Cut-to-Length Flexibility — Available in 1M, 2M, 5M, and 10M rolls so you can buy exactly what your project needs — whether it's a single battery wrap or a full wiring harness job.
🏠Versatile Application — Suitable for DIY battery pack assembly, e-bike builds, automotive cable management, marine wiring, and workshop organization where large diameter heat shrink tubing is required.

⚠️ Sizing Tip: The width listed (e.g., 70mm) is the flat width of the tubing before shrinking. The inner diameter (Ø44mm for the 70mm width) is the usable opening. Always confirm your component's outer diameter before selecting a size.

❓ Frequently Asked Questions

How do I choose the right diameter for my application?

Measure the outer diameter of the object you want to cover. The tubing's inner diameter (Ø) should be slightly larger than your object before shrinking. For example, if your battery pack measures 42mm across, the 70mm width (Ø44mm inner diameter) is typically a good fit. After heat is applied, PVC heat shrink tubing generally shrinks to roughly 50% of its original inner diameter.

What shrink ratio does this PVC tubing have?

This PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its supplied inner diameter when heat is applied evenly with a heat gun or similar tool.

Can I use this tubing outdoors or in wet environments?

Standard PVC heat shrink tubing provides basic moisture resistance and is suitable for light indoor and outdoor use. For fully waterproof or submersion applications, an adhesive-lined heat shrink tubing is typically recommended instead.

What temperature is needed to shrink this tubing?

PVC heat shrink tubing generally begins to shrink at around 70–90°C (158–194°F). A standard heat gun set to low or medium is typically sufficient. Avoid open flames, as uneven heat can scorch or deform the tubing.

Is this tubing compatible with 18650 and 21700 battery cells?

Yes. The 70mm width (Ø44mm inner diameter) is commonly used for wrapping individual 18650 cells or small battery packs. Larger widths such as 80mm or 85mm are generally suited for 21700 cells or multi-cell packs. Always verify your pack's outer diameter before ordering.

How much length do I need for my project?

For a single 18650 cell (typically about 65mm / ≈2.6" long), a 1M (≈39.4") roll provides enough material for many wraps. For larger battery packs or cable harness projects, the 5M (≈196.9") or 10M (≈393.7") options offer better value per meter.

What colors are available and do they affect performance?

This tubing is available in Black, White, Green, Yellow, Blue, Red, Clear, Fruit Green, Silver Grey, and Purple. Color is purely cosmetic and does not affect the electrical or thermal performance of the tubing.
