What is the shrink ratio of this PVC tubing?

PVC heat shrink tubing typically has a 2:1 shrink ratio, meaning the 120mm flat-width tube shrinks down to approximately 60mm in diameter after applying heat. Always verify your battery or cable diameter before ordering.

Which color should I choose for my application?

Black is the most common choice for electrical and battery applications due to its UV resistance and professional appearance. Transparent is useful when you need to see labels or cell markings through the sleeve. Colored options (Green, Blue, White, Fruit Green) are popular for color-coding cable runs or adding a custom look to DIY builds.

120mm PVC Heat Shrink Tubing — Reliable Insulation for Battery Packs & Cable Wrapping

If you've ever finished building a battery pack or wiring harness only to find the insulation sleeve splitting, sliding off, or leaving bare conductors exposed, you know how critical the right heat shrink tubing is. This 120mm wide PVC heat shrink tubing is built for DIY builders, EV hobbyists, electricians, and workshop technicians who need a consistent, snug sleeve that stays put after shrinking.

Each order is a continuous length of flat-width PVC heat shrink tubing measuring 120mm (≈4.7") wide before shrinking. Available in lengths from 1 meter (≈3.3 ft) up to 20 meters (≈65.6 ft), and in six colors — Black, Green, Blue, Transparent, White, and Fruit Green — so you can match your project or color-code your cable runs. The tubing features a typical 2:1 shrink ratio, contracting to approximately 60mm (≈2.4") in diameter when heat is applied.

Typical use cases include wrapping multi-cell lithium battery packs for e-bikes and power tools, sleeving large-gauge wire bundles and cable looms in automotive or marine wiring, and protecting bus bars or terminal connections in solar and off-grid power systems. The transparent variant is especially useful when you need to keep cell labels or polarity markings visible through the sleeve.

🔌 Compatibility: Designed for large-format battery assemblies, multi-cell packs, prismatic cells, and grouped cylindrical cell arrays. Flat width 120mm (≈4.7") shrinks to approx. 60mm (≈2.4") diameter. Confirm your pack circumference before ordering.

✅ Key Features of These 120mm PVC Heat Shrink Tubing Sleeves

📏Wide 120mm Flat Width — Covers large battery packs and thick cable bundles that standard narrow tubing can't reach, shrinking to approximately 60mm diameter for a firm, conforming fit.
🎨Six Color Options — Choose from Black, Green, Blue, Transparent, White, or Fruit Green to color-code wiring harnesses or maintain a clean, organized build.
📐Flexible Length Selection — Available from 1 meter (≈3.3 ft) to 20 meters (≈65.6 ft), so you can order exactly what your battery pack wrapping or cable sleeving project requires without waste.
🔥Low Activation Temperature — PVC formulation typically activates at 70–90°C (158–194°F), compatible with standard heat guns for even, controlled shrinking without scorching.
✂️Easy to Cut & Reposition — Cuts cleanly with scissors before shrinking; slides freely over components for precise positioning before heat is applied, reducing installation errors.
🛡️Moisture-Resistant Insulation — Forms a tight, moisture-resistant sleeve around terminals, bus bars, and cable joints, helping protect connections from dust, humidity, and incidental contact.

⚠️ Sizing Note: Measure the circumference of your battery pack or cable bundle and confirm it falls within the recovered diameter range before ordering. When in doubt, size up — a slightly looser fit before shrinking is easier to work with than a sleeve that won't slide on.

❓ Frequently Asked Questions

What length of heat shrink tubing do I need for my battery pack?

Measure the total length of the battery cells or cable run you need to cover, then add at least 10–15% extra for overlap and trimming. For a single row of cells, 1 meter is typically sufficient. Longer packs or full cable runs generally call for 2–5 meters. For workshop or production use, the 8–20 meter options offer the best value per meter. As a reference: 1 meter ≈ 3.3 ft, 5 meters ≈ 16.4 ft, 10 meters ≈ 32.8 ft.

What is the shrink ratio, and how small will it get after heating?

PVC heat shrink tubing typically has a 2:1 shrink ratio. Starting at 120mm (≈4.7") flat width, the tubing generally recovers to approximately 60mm (≈2.4") in diameter after applying heat. Always verify your battery pack or cable bundle circumference against this recovered diameter before ordering.

Can this tubing be used outdoors or in wet environments?

This PVC heat shrink tubing provides a moisture-resistant sleeve that is generally suitable for indoor and light outdoor use — protecting against dust, humidity, and incidental splashing. For fully waterproof or submersion-rated applications, a dual-wall adhesive-lined heat shrink is typically recommended instead. Contact us to confirm suitability for your specific environment.

Is this compatible with 18650, 21700, or other cylindrical battery cells?

At 120mm flat width, this tubing is designed for larger battery assemblies — multi-cell packs, prismatic cells, or grouped cylindrical cell arrays — rather than individual 18650 or 21700 cells. Individual cylindrical cells typically require much narrower tubing (18–30mm flat width). Contact us to confirm fit for your specific pack dimensions.

What temperature and tool do I need to shrink this tubing?

PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). A standard heat gun set to low or medium is the most reliable method — move it steadily along the tubing to shrink evenly. Avoid open flames or excessive heat concentration, which can scorch or unevenly shrink the material.

Which color should I choose for my project?

Black is the most common choice for electrical and battery applications — it offers a professional appearance and is generally more UV-stable than lighter colors. Transparent is ideal when you need to keep cell labels, polarity markings, or serial numbers visible through the sleeve. Colored options (Green, Blue, White, Fruit Green) are popular for color-coding cable runs in multi-circuit wiring harnesses or adding a custom look to DIY builds.

Can I cut this tubing to a custom length before shrinking?

Yes. PVC heat shrink tubing cuts cleanly with scissors or a utility knife before heat is applied. Cut to your desired length, slide the tube over the component, position it carefully, then apply heat. Any unused portion can be stored flat and reused for future projects.
