Heat Shrink Tubing Rc 3.0 2:1 Red-Black Set 2 (1 + 1 )

RC Heat Shrink Tube 3.0 mm 2:1 Red-Black Set 2 m

Durable 3 mm 2:1 Heat Shrink Tube for Insulating RC and FPV Cables

Heat shrink tube 3.0 mm (2:1) made of flexible polyolefin ensures effective wire insulation, solder protection, and organization of electrical installations in RC and FPV models. After heating, it shrinks to approximately 1.5 mm, maintaining high mechanical and thermal resistance.

The kit includes 1m of red tubing and 1m of black tubing, ideal for marking polarity.

Key Features and Benefits

• • 2:1 Shrink - when heated, the tubing reduces its diameter by half (from 3.0mm to approx. 1.5mm)

• • Universal 3mm diameter - ideal for 20-24 AWG wires used in FPV and RC electronics

• • 1m of red + 1m of black tubing - allows for polarity marking

• • Chemical resistance - resistant to grease, fuels and oils

• • Environmental resistance - resistant to UV, moisture and variable temperatures

• • Halogen-free material - safe to use

• • High flexibility and durability - protects against abrasion and damage

• • Aesthetic finish of the installation - ideal for organizing cables

• • Easy application - quick shrinking with a heat gun or hot air

• • Operating temperature range: -55°C to +125°C

• • High mechanical resistance - protects cables against abrasion

Frequently asked questions

WHAT IS THE 3 MM HEAT SHRINK TUBE USED FOR?

The 3 mm heat shrink tube is used to insulate wires, protect solders, mark polarity and protect 20-24 AWG cables in FPV and RC.

IS 3MM TUBE SUITABLE FOR FPV DRONES?

Yes, it is a perfect fit for silicone tubing used in FC, ESC, motors and FPV systems.

AT WHAT TEMPERATURE DOES IT SHRINK?

The shrinkage process begins above 90°C and is fully shrunk at 110-120°C.

WHAT IS THE SHRINKAGE RATIO?

2:1 - from 3.0mm to approximately 1.5mm after heating.

Can the heat shrink tubing be cut?

Yes, the tubing can be easily cut to any length. It is recommended to leave a few millimeters extra on each side for a better fit.

IS THIS KIT SUITABLE FOR POLARITY MARKING?

Yes - red tubing is positive, black tubing is negative.
