PVC Heat Shrink Tubing 40mm Flat Width — Reliable Insulation for AA Batteries & Wire Bundles

Whether you're rebuilding a battery pack, color-coding wire harnesses, or protecting exposed terminals, finding tubing that actually fits without guesswork is half the battle. This PVC heat shrink tubing is sized specifically for No.5 / AA batteries and similarly dimensioned cylindrical components, so you spend less time hunting for the right fit and more time finishing the job.

Each roll is made from flexible PVC with a flat width of 40mm (≈1.57") and an expanded inner diameter of approximately 25.5mm (≈1"). Available in lengths of 1m (≈3.3 ft), 3m (≈9.8 ft), 5m (≈16.4 ft), 20m (≈65.6 ft), and 100m (≈328 ft), and offered in 9 colors — Black, White, Yellow, Green, Blue, Red, Transparent, Fruit Green, and Light Green — so you can match your project or build a color-coding system from a single source.

Typical applications include DIY battery pack wrapping for 18650 and AA cells, electrical wire insulation and bundling in automotive and home wiring projects, and component labeling in electronics repair shops where color-coded heat shrink tubing for wire identification keeps assemblies organized and traceable.

🔵 Compatibility: Designed to fit No.5 / AA batteries (Ø~14.5mm) and cylindrical objects up to approximately 25.5mm (≈1") in diameter before shrinking. Verify your component diameter against the expanded inner diameter before ordering.

✅ Key Features of These 40mm PVC Heat Shrink Tubes

  • 🎨9 Color Options — Black, White, Yellow, Green, Blue, Red, Transparent, Fruit Green, and Light Green let you build a complete color-coded heat shrink tubing system for wire identification in a single order.
  • 📏Precise 40mm Flat Width — Engineered to match the diameter of No.5 / AA batteries and 18650 cells, eliminating the trial-and-error of sizing up generic tubing rolls.
  • ⚡Electrical Insulation — PVC construction provides a reliable insulating layer over terminals, solder joints, and wire splices, reducing the risk of shorts in battery packs and wiring harnesses.
  • ✂️Easy to Cut & Apply — Cuts cleanly with scissors or a utility knife; shrinks evenly with a heat gun for a snug, wrinkle-free finish on battery wrapping and wire bundling tasks.
  • 📦Flexible Quantity Options — From 1m sample rolls to 100m bulk spools, you can match your purchase to the project scale — whether it's a one-off repair or ongoing production use.
  • 🔄~2:1 Shrink Ratio — Typically shrinks to approximately half its expanded diameter, conforming closely to the underlying surface for a clean, professional appearance on finished assemblies.

❓ Frequently Asked Questions

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

Measure the total length of the area you need to cover, then add 10–15% extra for overlap and shrinkage. For single batteries or short wire runs, 1m is typically sufficient. For production runs or bulk wiring projects, the 20m or 100m rolls offer the best value per meter. As a reference: 1m ≈ 3.3 ft, 5m ≈ 16.4 ft, 20m ≈ 65.6 ft.

What is the shrink ratio, and how much will the tubing tighten down?

PVC heat shrink tubing generally has a shrink ratio of approximately 2:1, meaning it shrinks to roughly half its expanded diameter when heat is applied. The flat width of 40mm (≈1.57") corresponds to an expanded inner diameter of approximately 25.5mm (≈1"). After shrinking, the tubing will conform closely to the surface of the object.

Can this tubing be used outdoors or in wet environments?

Standard PVC heat shrink tubing is generally suitable for indoor use and light moisture exposure. For prolonged outdoor use, UV exposure, or submersion, a dual-wall adhesive-lined heat shrink tubing is typically recommended for a watertight seal. If outdoor durability is a priority, contact us to confirm the best option for your application.

What objects does the 40mm flat width fit?

With a 40mm flat width and approximately 25.5mm expanded inner diameter, this tubing is designed to fit No.5 (AA) batteries and similarly sized cylindrical objects — including 18650 lithium cells, small capacitors, and wire bundles of comparable diameter. Always verify your component's outer diameter before ordering.

What tool do I use to shrink this tubing?

A heat gun is the most reliable tool for even, controlled shrinking. In a pinch, a lighter or hair dryer can work for small sections, but a heat gun provides a cleaner finish. Move the heat source steadily along the tubing to avoid hot spots. Avoid direct open flame contact with the tubing surface to prevent scorching.

Is this tubing safe for battery pack rebuilding and DIY electronics?

Yes. PVC heat shrink tubing is commonly used for battery pack wrapping and cell insulation in DIY electronics projects. It provides electrical insulation and a clean, professional appearance. Always ensure the tubing is fully shrunk and free of gaps before use in any electrical application. For high-current or high-temperature environments, contact us to confirm suitability.

Can I cut this tubing to custom lengths?

Absolutely. PVC heat shrink tubing cuts cleanly with scissors or a utility knife. Cut to your desired length before applying heat, as the material becomes less flexible once shrunk. For very short pieces, a sharp blade gives the cleanest edge.
