Red Heat Shrink Tubing 2:1

2:1 Heat shrink – reliable insulation for crimp terminals and cable ends

Our heat shrink tubing is designed to provide extra protection, stability, and sealing for cable ends and crimp connections.
It insulates and reinforces crimped terminals by covering both the cable and the terminal lug, ensuring a secure, moisture-resistant, and professional-grade finish.

Ideal for use in automotive, marine, and industrial electrical systems, this tubing combines excellent electrical and mechanical properties with outstanding resistance to acids, corrosion, and abrasion.
It produces very little smoke and contains no halogens or cadmium, ensuring a safer and more environmentally friendly installation.

Key Benefits:

Reliable insulation and strain relief for crimped connections and cable ends
Easy to use – shrinks quickly and evenly with a heat gun
Excellent chemical and mechanical resistance – protects against acids and corrosion
Low smoke and halogen-free – safe for confined or sensitive environments
Ideal for marine and automotive electrical systems – durable and long-lasting

How to Use

Place the heat shrink tubing over the cable and crimp terminal.
Make sure the contact surface of the terminal is clean and free from debris.
Apply heat evenly with a heat gun until the tubing shrinks tightly and the adhesive activates, creating a strong and sealed insulation.

This 2:1 heat shrink tubing provides excellent electrical insulation and mechanical protection in electrical systems.
Its halogen-free, flame-retardant construction makes it especially suitable for marine, automotive, and industrial wiring applications where long-term safety and reliability are essential.
