PVC Heat Shrink Tubing 45–120mm — Reliable Insulation for Battery Packs & Wire Bundles

Whether you're rebuilding a lithium-ion battery pack, organizing a wiring harness, or protecting bare conductors on a DIY electronics project, finding tubing that actually fits — and stays put — is half the battle. Loose sleeves slip, undersized tubing won't close, and the wrong material can crack under heat. This PVC heat shrink tubing is sized to cover the full range of common battery cells and wire bundles, so you can stop guessing and start building.

Each roll is made from flexible PVC with a 2:1 shrink ratio. Flat widths run from 45mm (≈1.77") to 120mm (≈4.72"), covering diameters typically from about 25mm up to 75mm when fully shrunk. Lengths are available in 1m (≈3.3 ft) for single-use jobs and 5m (≈16.4 ft) for workshop stock. Thirteen color options — including Black, White, Red, Blue, Yellow, Green, Transparent, Silver Gray, Purple, Fruit Green, Orange, Orange Red, and Light Yellow — make color-coding wire gauges or battery types straightforward.

Typical use cases include wrapping 18650 and 21700 lithium-ion cells for e-bike and power tool battery packs, sleeving automotive wire splices and trailer harnesses, bundling low-voltage DC cables in home automation setups, and protecting copper bus bars in DIY solar battery banks. The wide flat-width range means one product line covers most heat shrink tubing for battery packs needs without ordering from multiple suppliers.

🔌 Compatibility Note: Flat width determines fit — not the finished diameter. Measure your object's diameter and multiply by ~1.57 to find the minimum flat width required. See the FAQ below for a step-by-step guide.

✅ Key Features of These PVC Heat Shrink Tubing Rolls

  • 📐Wide Size Range — Flat widths from 45mm to 120mm in 17 increments cover battery cells, wire bundles, and tubing across a broad diameter range without needing multiple product lines.
  • 🎨13 Color Options — From classic Black and White to Transparent and Silver Gray, color-coding wire gauges or battery types helps reduce wiring errors in complex DIY electronics builds.
  • 🔥Low Activation Temperature — PVC heat shrink tubing typically begins shrinking at around 70–90°C, so a standard heat gun on low setting is all you need — no specialized equipment required.
  • ⚡Flexible PVC Construction — Remains pliable after shrinking, making it well-suited for battery pack wrapping where slight flex is needed to avoid cracking on curved cell surfaces.
  • 📏Two Length Options — The 1m roll suits single repairs or prototyping; the 5m roll provides better value per meter for workshop stock or batch production of heat shrink tubing for wire insulation projects.
  • 🛡️Moisture-Resistant Sleeve — Provides a protective barrier against light moisture, dust, and abrasion, helping extend the service life of wrapped battery terminals and wire splices in indoor and light outdoor environments.

⚠️ Sizing Tip: If you are between two flat widths, size up — tubing that is slightly oversized before shrinking will still conform tightly. Tubing that is undersized cannot be stretched to fit.

❓ Frequently Asked Questions

How do I choose the right flat width for my application?

Measure the diameter of the object you want to cover, then multiply by approximately 1.57 to get the minimum flat width needed. For example, a 25mm diameter battery cell typically requires a flat width of at least 40mm — so the 45mm option would be the closest fit. This product covers flat widths from 45mm (≈1.77") to 120mm (≈4.72"), accommodating most common battery pack and wire bundle diameters. When in doubt, size up by one increment.

What shrink ratio does this PVC tubing have?

PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to roughly half its original flat width when heat is applied. This is generally sufficient for snug coverage on cylindrical battery cells, wire harnesses, and similar objects. If you need a tighter grip or a higher shrink ratio, polyolefin tubing may be a better fit for your project.

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 heat gun set to low or medium is the most common and recommended tool. Move the heat gun steadily along the tubing to avoid hot spots. A lighter can work for very short sections, but a heat gun gives the most even, controlled result — especially on wider widths like 80mm or 120mm.

Can this tubing be used outdoors or in wet environments?

PVC heat shrink tubing provides a degree of moisture resistance and is suitable for light indoor and outdoor use — for example, protecting wire splices in a garage or under a vehicle hood. It is not rated for continuous submersion or prolonged UV exposure. For demanding outdoor, waterproof, or marine applications, adhesive-lined polyolefin tubing is generally a better choice.

Is this tubing compatible with lithium-ion battery packs?

Yes. PVC heat shrink tubing is widely used for wrapping 18650, 21700, and other cylindrical lithium-ion cells, as well as assembled battery packs for e-bikes, power tools, and DIY energy storage. The flat widths available (45–120mm) cover most common cell and pack sizes. Always confirm the flat width matches your pack's outer diameter before ordering — use the formula: flat width needed ≈ pack diameter × 1.57.

How much length do I need — 1m or 5m?

The 1m (≈3.3 ft) roll is ideal for small repairs, wrapping a single battery cell, or one-off prototyping. The 5m (≈16.4 ft) roll offers better value per meter and is suited for workshop stock, batch production, or anyone who regularly wraps wire bundles or battery packs. Both lengths are cut from the same tubing stock and have identical material properties.

Does the color affect performance or shrink behavior?

No — all 13 color variants share the same material properties and shrink characteristics. Color choice is purely for identification, organization, or aesthetics. Using different colors for different wire gauges, voltage levels, or battery types is a common practice in DIY electronics, automotive wiring, and solar installations. Transparent tubing is useful when you want to keep labels or markings visible after shrinking.
