Heat Shrink Tubing 5.0 mm 2:1 red + black set 2 m

Durable 5 mm heat shrink tubing for RC and FPV cable insulation and solder protection

The 5.0 mm (2:1) heat shrink tubing made of high-quality polyolefin provides reliable insulation, solder joint protection and clean wire organization in RC and FPV electronics. When heated, it shrinks down to approximately 2.5 mm, creating a strong and flexible protective layer. The set includes 1 m red and 1 m black tubing for easy polarity marking.

Key features and benefits

  • • 2:1 shrink ratio — from 5 mm down to approx. 2.5 mm
  • • Suitable for 14–18 AWG wires
  • • Includes 1 m red + 1 m black tubing for polarity identification
  • • Chemical resistance to oils, greases and fuels
  • • Environmental resistance — UV, moisture and temperature variations
  • • Halogen-free material — safe for electronics and handling
  • • High flexibility and mechanical durability
  • • Clean and professional wire routing
  • • Easy to apply with a heat gun or hot-air
  • • Working range: –55°C to +125°C
  • • Strong abrasion resistance

Applications

  • • Insulating 14–18 AWG silicone wires
  • • Protecting XT30 / XT60 solder joints
  • • Securing motor and power leads
  • • Polarity marking (red = positive, black = negative)
  • • Cable organization in FPV and RC models

How to use

  • • Cut the tubing to the required length
  • • Slide it over the wire or solder joint
  • • Apply even heat (heat gun or hot-air)
  • • The tubing shrinks to approx. 2.5 mm
  • • Allow it to cool before handling


How to choose the correct size

5.0 mm tubing is ideal for wires with an outer diameter of 2.6–4.0 mm, such as:

  • • 14–18 AWG silicone wires
  • • servo wires and power leads
  • • wiring in larger RC models

In the box

  • • 1 m red 5.0 mm heat shrink tubing
  • • 1 m black 5.0 mm heat shrink tubing
