PVC Heat Shrink Tubing — Reliable Wire Insulation for RC Batteries & DIY Electronics
Loose wires, exposed solder joints, and unprotected battery packs are a constant headache for RC hobbyists, electronics builders, and DIY repair enthusiasts. One slip during a run can mean a short circuit, a damaged pack, or a failed project. This PVC heat shrink tubing gives you a clean, secure, and color-coded solution that goes on fast and stays put.
Each order includes your chosen length of PVC heat shrink tubing — available in 1m (≈39"), 2m (≈79"), 3m (≈118"), or 5m (≈197") cuts — with outer diameters ranging from 7mm (≈9/32") up to 130mm (≈5-1/8") and inner diameters from Ø4mm to Ø83mm. The tubing is made from flexible PVC with a 2:1 shrink ratio and is available in 30+ colors including Black, White, Blue, Red, Green, Yellow, Transparent, and specialty finishes like Tyrant Gold and Transparent Gold.
Typical use cases include wrapping RC LiPo, NiMH, and NiCd battery packs to hold cells together and provide electrical insulation; protecting soldered wire joints and connector terminals in automotive and hobby wiring; and color-coding cable harnesses in electronics assembly and DIY repair projects.
🔌
Compatibility: Suitable for RC battery packs (LiPo, NiMH, NiCd), wire harnesses, connector insulation, and general electrical DIY. Select the diameter whose inner Ø is slightly larger than your component before shrinking.
✅ Key Features of These PVC Heat Shrink Tubes
-
📐Wide Size Range — Outer diameters from 7mm to 130mm (inner Ø4mm–Ø83mm) cover everything from thin signal wires to large RC battery packs in a single product line.
-
🎨30+ Color Options — From standard Black, White, Blue, and Red to specialty finishes like Transparent Gold and Tyrant Gold, making color-coded wire management straightforward and consistent.

Size Note: The "Width(Dia)" shown in the variant selector is the outer diameter of the tubing before shrinking. The inner diameter (Ø) is listed in parentheses — e.g., "17mm (Ø10.8mm)" means the tubing is 17mm wide with a 10.8mm inner bore. Always match the inner Ø to your component size.
❓ Frequently Asked Questions
How do I choose the right diameter of PVC heat shrink tubing?
Select a tubing whose inner diameter (Ø) is slightly larger than the widest part of the object you need to cover. For example, a 7mm wide tube has an inner diameter of Ø4mm — suitable for thin wires or small connectors. PVC heat shrink tubing typically shrinks to roughly half its supplied diameter when heat is applied, so always measure your component first and choose the next size up. If you are between sizes, size up rather than down.
What shrink ratio does this PVC heat shrink tubing have?
PVC heat shrink tubing generally has a 2:1 shrink ratio, meaning it shrinks to approximately half its original inner diameter when heated. The exact ratio can vary slightly by size — contact us to confirm for a specific variant.
Can I use this tubing outdoors or in wet environments?
PVC heat shrink tubing provides basic moisture resistance and is generally suitable for indoor and light outdoor use. For prolonged outdoor exposure, UV-heavy environments, or submersion, an adhesive-lined or polyolefin tubing is typically recommended. Contact us if you need guidance for a specific application.
Is this tubing compatible with LiPo, NiMH, and NiCd battery packs?
Yes. This PVC heat shrink tubing is widely used to wrap and insulate RC battery packs including LiPo, NiMH, and NiCd cells. Choose a diameter that fits snugly over your battery pack. The tubing provides electrical insulation and helps hold cells together during use.
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, which can scorch or melt the material unevenly. Always apply heat evenly along the length of the tubing.
How do I select the right length for my project?
This tubing is sold by the meter (1m, 2m, 3m, or 5m per order). Measure the total length of wire, battery, or component you need to cover, then add a small margin for overlap at each end. For battery packs, generally 1–2m is sufficient for most RC applications; larger packs or multiple wraps may require 3m or more.
Can this tubing be used for electrical wire insulation and cable management?
Yes. In addition to battery wrapping, this PVC heat shrink tubing is commonly used for wire insulation, cable bundling, connector protection, and color-coding wiring harnesses in automotive, hobby, and DIY electronics projects.
