PVC Heat Shrink Tubing 55mm Flat Width — Clean, Durable Battery Pack Wrapping

If you've ever finished building a custom battery pack only to have it look rough, unprotected, or prone to short circuits from exposed cells, you know how important the final wrap is. DIY electronics builders, RC hobbyists, and e-bike battery assemblers rely on PVC heat shrink tubing to give their packs a professional, insulated finish that holds up in real use.

This listing is for PVC heat shrink tubing with a 55mm flat width, which expands to an inner diameter of approximately Ø35mm (≈1-3/8") before shrinking. It is sold by the meter in rolls of 1m, 3m, 5m, 20m, and 100m, and is available in 10 colors: Black, White, Yellow, Green, Blue, Red, Transparent, Orange-Red, Orange, and Light Yellow. The tubing features a typical 2:1 shrink ratio, recovering to approximately 17–18mm inner diameter after heat is applied.

Typical use cases include wrapping custom AAA and AA battery packs for RC vehicles and power tools, insulating wire harness bundles in automotive and marine wiring projects, and providing a color-coded sleeve over cable splices and electrical connections in home automation and DIY electronics builds.

ℹ️ Compatibility Note: This tubing fits cylindrical battery packs or wire bundles up to approximately 33mm in diameter before shrinking. Flat width 55mm = expanded Ø≈35mm. Verify your pack diameter before ordering.

✅ Key Features of These PVC Heat Shrink Tubing Wraps

  • 🔋Battery Pack Ready — 55mm flat width (Ø35mm expanded) is sized specifically for AAA, AA, and small cylindrical cell battery pack wrapping, giving packs a clean, insulated finish.
  • 🎨10 Color Options — Available in Black, White, Yellow, Green, Blue, Red, Transparent, Orange-Red, Orange, and Light Yellow for color-coded wiring, polarity identification, or aesthetic customization.
  • ⚡Electrical Insulation — PVC construction provides low-voltage electrical insulation, generally rated up to 600V, protecting exposed conductors and battery cell contacts from accidental shorts.
  • 🔥2:1 Shrink Ratio — Activates at typically 70°C–110°C (158°F–230°F) with a standard heat gun; shrinks uniformly around irregular shapes without cracking or splitting.
  • 📏Flexible Length Options — Order exactly what you need: 1m for single-pack jobs, 3m or 5m for small production runs, or 20m and 100m rolls for workshop stock and bulk battery assembly projects.
  • ✂️Easy to Cut and Apply — Cuts cleanly with standard scissors; slides over battery packs and wire bundles without adhesive, then conforms tightly when heat is applied for a snag-free, professional result.

❓ Frequently Asked Questions

What does 55mm flat width mean, and what diameter wire or battery pack will it fit?

Flat width is the measurement of the tubing when laid flat. This product has a 55mm flat width, which corresponds to an expanded inner diameter of approximately Ø35mm (≈1-3/8"). After shrinking, the recovered diameter is typically around 17–18mm. It is generally suited for cylindrical battery packs or wire bundles up to about 33mm in diameter before shrinking.

What is the shrink ratio, and how much will it tighten around my pack?

PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning it shrinks to approximately half its expanded diameter when heat is applied. For this 55mm flat-width tubing, the recovered inner diameter is generally around 17–18mm. It will conform snugly around battery packs and wire bundles within that range.

What temperature do I need to shrink this tubing, and can I use a heat gun?

PVC heat shrink tubing generally activates at 70°C–110°C (158°F–230°F). A heat gun set to low or medium is the recommended tool. Move the heat gun evenly along the tubing to avoid hot spots. Avoid open flames — PVC can scorch or release fumes if overheated.

Can this tubing be used outdoors or in wet/damp environments?

PVC heat shrink tubing provides basic moisture resistance and is suitable for light indoor and sheltered outdoor use. For prolonged outdoor exposure, UV resistance, or submersion, a dual-wall adhesive-lined heat shrink tubing is generally recommended instead. Contact us if you need guidance on the right product for your environment.

Is this compatible with lithium-ion, NiMH, and NiCd battery packs?

Yes. This tubing is commonly used to wrap custom lithium-ion, NiMH, and NiCd battery packs. It provides electrical insulation and a clean finished appearance. Always verify the expanded diameter fits your pack before shrinking — the pack must be smaller than Ø35mm to slide the tubing on.

How do I choose the right length for my project?

Measure the total length of the battery pack or wire bundle you need to cover, then add 10–15% for overlap and trimming. For example, a single AAA battery pack is typically about 44mm (≈1-3/4") long — 1m is generally more than sufficient for multiple packs. For larger projects or production runs, the 20m or 100m rolls offer better value per meter.

Does the color affect shrink performance or insulation properties?

No. Color is purely cosmetic and does not affect shrink ratio, insulation properties, or heat activation temperature. All 10 colors — Black, White, Yellow, Green, Blue, Red, Transparent, Orange-Red, Orange, and Light Yellow — perform identically. Color-coding is useful for polarity identification or circuit organization in multi-wire harness projects.

What is the voltage rating, and is this suitable for automotive or marine wiring?

PVC heat shrink tubing of this type is generally rated for low-voltage applications up to 600V, making it suitable for automotive 12V/24V systems, marine wiring, and DIY electronics. For high-voltage or industrial electrical applications, please contact us to confirm suitability before ordering.
