PVC Heat Shrink Tubing — Reliable Wire & Battery Pack Protection in 49 Sizes

Whether you're rebuilding an RC battery pack, bundling a wiring harness, or insulating a DIY electronics project, loose or exposed wires create real risks — short circuits, abrasion damage, and failed connections. This PVC heat shrink tubing gives hobbyists, makers, and technicians a clean, secure way to protect and organize cables of virtually any diameter, from a 4mm wire up to a 286mm battery pack.

Each listing covers 1 meter (≈39.4") of tubing in your chosen flat width and color. Flat widths range from 7mm (Φ4mm recovered) all the way to 450mm (Φ286mm recovered), covering 49 distinct sizes. The tubing is made from flexible PVC with a 2:1 shrink ratio — apply heat and it conforms snugly around your component. Colors available include Transparent, Black, White, Blue, Red, Green, Fruit Green, Yellow, Purple, Pink, Orange, and Light Green, making color-coding wiring systems straightforward.

Typical use cases include wrapping LiPo, NiMH, and NiCd RC battery packs to restore or replace worn outer sleeves, insulating wire splices and solder joints on automotive or marine wiring, bundling cable runs in home theater or workshop installations, and protecting copper pipe fittings or conduit ends from corrosion and abrasion.

ℹ️ Compatibility note: The flat width listed is the collapsed (pre-shrink) diameter. The inner diameter after shrinking is shown as Φ in each size option. To wrap a round object, choose a flat width ≥ (object OD × 1.57) + 10% clearance. When in doubt, size up.

✅ Key Features of These PVC Heat Shrink Tubes

📐49 Flat-Width Sizes — From 7mm (Φ4mm) to 450mm (Φ286mm), this range covers everything from thin signal wires to large-format RC battery packs and conduit bundles, eliminating the need to source multiple products.
🎨12 Color Options — Transparent, Black, White, Blue, Red, Green, Fruit Green, Yellow, Purple, Pink, Orange, and Light Green allow color-coded wire identification and a clean finished appearance on battery packs and cable assemblies.
🔥2:1 Shrink Ratio — PVC heat shrink tubing with a 2:1 ratio conforms tightly to irregular shapes when heated to approximately 70–90°C (158–194°F), creating a firm, abrasion-resistant sleeve without adhesive mess.
✂️Cut-to-Length Flexibility — Each 1-meter length can be trimmed to any size before shrinking, making it practical for short wire splice insulation as well as full-length battery pack rewrapping in a single piece.
🔋RC Battery Pack Compatible — Sized specifically to fit LiPo, NiMH, and NiCd battery pack formats commonly used in RC cars, planes, and drones, replacing cracked or peeling factory sleeves cleanly and securely.
🛡️Moisture & Abrasion Resistance — PVC construction provides a protective barrier against light moisture, dust, and mechanical abrasion, helping extend the service life of wire connections and battery pack exteriors in workshop and field environments.

⚠️ Sizing tip: If you are unsure which flat width fits your battery pack or wire bundle, measure the object's outer diameter in mm and multiply by 1.57 to get the minimum flat width required. We recommend selecting the next size up for easy insertion before shrinking.

❓ Frequently Asked Questions

How do I choose the right size heat shrink tubing for my wire or battery pack?

The listed width is the flat (collapsed) diameter. After shrinking, the tubing typically reduces to roughly 50% of its flat width. For a wire or battery pack with a circular cross-section, choose a flat width that is at least 10–20% larger than the object's diameter before shrinking. For example, a 25mm diameter battery pack generally fits well inside a 29.5mm or 31mm flat-width tube. When in doubt, size up — you can always trim excess length.

What is the shrink ratio of this PVC heat shrink tubing?

This PVC tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original flat width when heat is applied. The inner diameter listed (Φ) in each size option represents the approximate recovered diameter after shrinking.

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 recommended. Avoid open flames, as they can scorch or melt the tubing unevenly. Move the heat source steadily along the tube to shrink evenly from one end to the other.

Can this tubing be used outdoors or in wet environments?

PVC heat shrink tubing provides basic moisture resistance and is suitable for general indoor and light outdoor use. However, it is not rated for continuous submersion or prolonged UV exposure. For demanding outdoor, marine, or underground applications, a polyolefin or adhesive-lined tubing is generally a better choice.

Is this tubing compatible with LiPo, NiMH, and NiCd RC battery packs?

Yes. This tubing is widely used to wrap and protect RC battery packs including LiPo, NiMH, and NiCd chemistries. Select the flat width that matches or slightly exceeds your battery pack's circumference divided by π — or simply measure the pack's widest flat dimension and add 10–15% clearance. The Φ (recovered diameter) listed in each size option can also help you verify fit.

How do I calculate which flat width I need for a round object?

Measure the outer diameter of your object in mm, then multiply by 1.57 (π ÷ 2) to get the minimum flat width needed. For example, a 20mm diameter rod needs at least a 31mm flat-width tube. We recommend going one size up for easy insertion before applying heat.

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

Yes. Each roll is 1 meter (≈39.4 inches) long and can be cut to any length with scissors or a utility knife before applying heat. Cut cleanly at a right angle to prevent fraying at the ends.

Does the transparent option provide the same protection as colored versions?

Yes. The transparent variant is made from the same PVC material and offers the same shrink ratio and mechanical protection as the colored options. It is a popular choice when you want to display labels, markings, or the underlying wire color while still providing insulation and abrasion resistance.
