Wireless accessory for battery assembly that provides reliable insulation and mechanical protection: Hoggy Heat Shrink Tubing. Confidence for hobbyists and technicians who need neat, secure 18650 or 26650 packs. Is the 2 metres of 230mm x 0.15mm tubing the right fit for your builds?
⚡ At a Glance
- • Shrink Performance: Shrinks by at least 48% when heated to 80°C for a tight fit
- • Best for: Building and insulating 18650 or 26650 battery packs
- • Not ideal for: Very fine cable insulation or applications needing different shrink ratios
Two metres of 230mm PVC heat shrink tubing achieves ≥48% shrinkage at 80°C. Offers robust mechanical protection and acts as an electrical insulator for battery packs.
Secure, snug seals – thanks to ≥48% shrinkage at 80°C
A shrinkage ratio of at least 48% at a target temperature of 80°C reduces the cross-sectional size significantly when heated. The high shrink ratio forces the tubing to conform tightly around cylindrical cells and joins.
Tightly fitting sleeves hold cells and joints firmly in place, reducing movement during handling and transport.
Mechanical robustness – with 0.15mm PVC wall
PVC construction with a 0.15mm wall thickness provides a balance of flexibility and physical protection. The material resists abrasion and adds structural support around cell assemblies.
Added durability helps prevent knocks and scuffs from chafing battery surfaces, prolonging the life of pack assemblies.
Reliable electrical insulation – with PVC insulating properties
PVC is a recognised electrical insulator that prevents conductive contact between cells and external metalwork. The tubing’s material properties reduce the risk of shorts when properly applied.
Clear insulation reduces the chance of short circuits and makes handling safer during assembly and maintenance.
✨ The 4 Key Reasons for Hoggy Heat Shrink Tubing
- 2 metres total length – Enough tubing for several battery pack assemblies before replacement
- 230mm diameter – Covers larger cylindrical cells such as 18650 and 26650 packs neatly
- ≥48% shrinkage at 80°C – Creates a tight seal that secures cells during heat-shrinking
- PVC electrical insulation – Reduces short-circuit risk while adding durable mechanical protection

❓ Frequently Asked Questions
Q: What size and length does the tubing come in?
A: The tubing is supplied as 2 metres of PVC labelled 230mm x 0.15mm. Those dimensions are given in the product description.
Q: What temperature is required to shrink the tubing?
A: Heat to around 80°C for shrinkage, at which point the tubing will reduce in size by at least 48%.
Q: Is the tubing suitable for 18650 or 26650 battery packs?
A: Yes, the description specifies the tubing is for making 18650 or 26650 battery packs.
🏆 Our Verdict
Suitable for hobbyists and technicians assembling cylindrical cell battery packs, particularly 18650 and 26650 formats. High shrink ratio at 80°C, 0.15mm PVC construction and a generous 2-metre length deliver tight seals, mechanical robustness and reliable electrical insulation. Clear specifications and durable material make the tubing a practical, long-lasting choice for routine battery-building tasks.
