Heat Shrink Tubing 3.0 mm 2:1 red + black set 2 m

Durable 3 mm 2:1 heat shrink tubing for RC and FPV wiring

The 3.0 mm (2:1) heat shrink tubing made of flexible polyolefin provides reliable insulation, solder joint protection and cable management in RC and FPV electronics. After heating it shrinks to approx. 1.5 mm, offering excellent thermal and mechanical durability. The set includes 1 m red and 1 m black tubing for polarity marking.

Key features and benefits

  • • 2:1 shrink ratio — reduces from 3.0 mm to approx. 1.5 mm when heated
  • • Universal 3 mm size — suitable for 20–24 AWG wires used in RC and FPV
  • • Includes 1 m red + 1 m black tubing — ideal for polarity marking
  • • Chemical resistance — withstands oils, greases and model fuels
  • • Environmental resistance — resistant to moisture, UV and temperature changes
  • • Halogen-free material — safe for electronics and users
  • • High flexibility and durability — protects against abrasion and wear
  • • Clean and professional cable management
  • • Easy to apply — shrinks quickly with a heat gun or hot-air
  • • Operating temperature: –55°C to +125°C
  • • Strong mechanical protection — prevents cable damage

Technical specifications
