PVC Heat Shrink Tubing 23mm — Reliable Insulation for Battery Packs & Cable Sleeving

Whether you're rebuilding a lithium battery pack, tidying up a wiring harness, or protecting exposed terminals in an electronics project, finding heat shrink tubing that fits cleanly and shrinks evenly can be surprisingly frustrating. Loose fits, inconsistent shrinkage, and limited color options waste time and compromise the finished look. This 23mm PVC heat shrink tubing is designed for hobbyists, makers, and small-shop technicians who need a dependable, color-coded sleeving solution that works the first time.

Each roll consists of flat PVC heat shrink tubing with a pre-shrink width of 23mm and an inner diameter of approximately φ14.5mm (≈0.57"). The 2:1 shrink ratio means it contracts to roughly half its original diameter when heat is applied, conforming snugly around the covered component. Available in four roll lengths — 1M (≈39.4"), 3M (≈9.8 ft), 5M (≈16.4 ft), and 10M (≈32.8 ft) — and 15 distinct colors including Black, White, Red, Blue, Green, Yellow, Clear, and more.

Typical applications include wrapping 18650 lithium battery cell holders and battery pack assemblies, color-coding wire bundles in automotive and RC vehicle builds, and providing abrasion-resistant sleeving for exposed cable runs in workshop or garage environments.

ℹ️ Compatibility Note: Pre-shrink inner diameter is approximately φ14.5mm (≈0.57"). Fits cables and battery packs up to ~14mm in diameter. Measure your bundle before ordering. Shrink temperature: typically 70–90°C (158–194°F) — a heat gun is recommended.

✅ Key Features of These 23mm PVC Heat Shrink Tubing Rolls

  • 🔥2:1 Shrink Ratio — Contracts from 23mm down to approximately φ14.5mm, creating a firm, gap-free fit around battery packs, wire bundles, and cable terminations.
  • 🎨15 Color Options — Black, White, Red, Blue, Green, Yellow, Clear, Grey, Pink, Purple, Orange, Orange Red, Fruit Green, Dark Green, and Clear Gold for easy color-coded wire identification.
  • 📏Four Roll Lengths — Choose 1M, 3M, 5M, or 10M to match your project scale, from a single battery pack wrap to bulk cable sleeving for a full wiring job.
  • ✂️Clean-Cut PVC Material — Cuts smoothly with scissors or a utility knife before shrinking; the flat-tube format lays flat for easy storage and precise pre-cut sizing.
  • 🔋Battery Pack Ready — The 23mm width is well-suited for standard 18650 cell holders and single-row lithium battery pack assemblies commonly used in DIY power tools and RC builds.
  • 🛡️Insulation & Abrasion Protection — Provides electrical insulation and basic mechanical protection for exposed wire joints, terminals, and cable runs in workshop and electronics applications.

❓ Frequently Asked Questions

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

Measure the total length of wire, cable, or component you need to cover, then add 10–15% extra for overlap and trimming. For example, a 1-meter (≈39.4") roll typically covers a single battery pack connection or a short wiring harness. Choose 3M, 5M, or 10M rolls for larger projects or bulk wiring jobs.

What does 2:1 shrink ratio mean?

A 2:1 ratio means the tubing shrinks to approximately half its original diameter when heat is applied. This tubing starts at 23mm (≈0.91") and shrinks down to roughly φ14.5mm (≈0.57") inner diameter, conforming snugly around the covered component.

Can this heat shrink tubing be used outdoors?

PVC heat shrink tubing generally provides basic moisture and abrasion resistance suitable for indoor and sheltered outdoor use. For prolonged UV exposure or harsh outdoor environments, an adhesive-lined or polyolefin-based tubing is typically recommended. Please confirm suitability with your specific application requirements.

What wire or cable sizes fit inside this tubing?

With a pre-shrink inner diameter of approximately φ14.5mm (≈0.57"), this tubing generally fits cables, battery packs, or bundled wires up to about 14mm in diameter. After shrinking, it conforms tightly to the covered object. Always measure your cable bundle diameter before ordering.

What temperature is needed to shrink this tubing?

PVC heat shrink tubing typically activates at around 70–90°C (158–194°F). A heat gun set to low or medium is the most reliable tool. A lighter or hair dryer may work for small sections, but a heat gun provides the most even shrinkage. Avoid overheating, which can cause discoloration or cracking.

Is this tubing compatible with lithium battery packs?

Yes, this 23mm heat shrink tubing is commonly used to wrap and insulate lithium battery packs, 18650 cell holders, and similar assemblies. The 23mm pre-shrink width accommodates most standard single-row battery pack configurations. Confirm your pack dimensions before purchasing.

Can I cut the tubing to a custom length?

Absolutely. PVC heat shrink tubing cuts cleanly with scissors or a utility knife. Cut your desired length before applying heat — once shrunk, trimming is more difficult. The rolls come in 1M, 3M, 5M, and 10M options so you can choose the most economical size for your project.
