Overview

The LOGIC Heat Shrink (1m Red/1m Black) 5.0mm O-LG-HS05 is an essential accessory for any RC enthusiast working with electrical connections and wiring projects. Whether you're building a brushless RC car, setting up a new RC truck, or maintaining your existing RC models, this heat shrink tubing provides a professional, neat finish to your electrical work. Heat shrink is indispensable for protecting cable connections, insulating terminals, and creating clear colour-coded identification systems across your RC wiring—making it a must-have item in every RC modeller's workshop.

This convenient pack supplies two generous 1-metre lengths of heat shrink tubing in vibrant red and classic black, sized perfectly to fit over 5mm diameter wire. The dual-colour option means you can colour-code your electrical connections for easy identification during builds and repairs, a practice beloved by RC car UK enthusiasts and professional RC modellers alike. Whether you're working on brushless motor installations, speed controller connections, or general electrical protection on your RC buggy, truck, or aircraft, this heat shrink delivers reliable performance at an affordable price.

Manufactured to professional standards with flexible, flame-retardant materials, the LOGIC Heat Shrink meets the demands of serious RC hobbyists. The tubing features low-smoke characteristics if burned, making it safer to use in indoor workshop environments. With an impressive operating temperature range from -45°C to 125°C and a shrink temperature of 125°C, this heat shrink remains stable across the full spectrum of RC applications and environmental conditions you might encounter during outdoor bashing or indoor flying.

Key Features

• Dual Colour Pack — This pack includes 1 metre of red heat shrink and 1 metre of black heat shrink, allowing you to create colour-coded electrical systems that make circuit identification quick and easy during assembly, troubleshooting and repairs on your RC models.
• Perfect for 5mm Wire — The 5.0mm nominal diameter is engineered to fit securely over 5mm diameter wire with approximately 20% extra internal clearance when unexpanded, ensuring smooth application without forcing or bunching the material.
• 3:1 Shrink Ratio — This industry-standard shrink ratio means the 6mm expanded diameter recovers to approximately 2mm when heated, providing excellent coverage and a tight, professional seal around your connections and terminals.
• Flexible and Durable — The tubing remains flexible even after shrinking, allowing it to accommodate slight movements and vibrations common in RC applications without cracking or splitting, which is particularly important for dynamic RC vehicles subject to constant movement.
• Flame Retardant Construction — The flame-retardant properties make this heat shrink suitable for use near high-temperature components such as speed controllers and brushless motors, whilst the low-smoke formulation keeps your workshop environment safer when applying heat.
• Wide Temperature Range — Operating reliably from -45°C to 125°C, this heat shrink maintains its protective qualities in everything from frozen winter RC flying sessions to hot summer track days or bashing in the garden, making it suitable for year-round RC car UK use.
• Easy Application — Simply slide the tubing over your connection or wire, then apply heat using a heat gun, lighter, or hot air tool until the material shrinks snugly around the component—no special tools or training required.

Technical Performance

The LOGIC Heat Shrink is engineered with precision dimensions and material properties that meet the rigorous demands of RC electronics and wiring work. The un-shrunk expanded diameter measures exactly 6mm, providing comfortable clearance over 5mm diameter wire whilst remaining slim enough for tight spaces in compact RC chassis. Once heated to the activation temperature of 125°C, the tubing recovers to approximately 2mm internal diameter, creating a tight, protective seal that won't slip or rotate on your connections. The lay-flat width of 9.4mm indicates the tubing's width when compressed flat, useful for calculating space requirements when heat shrinking in confined areas. The material composition features flexible polymers that maintain their elasticity even after shrinking, preventing brittleness that could occur with inferior heat shrink products. The flame-retardant rating ensures safe use near high-temperature components common in RC speed controllers and brushless motor installations, whilst the low-smoke formulation makes it suitable for indoor workshops and sensitive environments. Quality control standards ensure consistent shrink temperatures and ratios across every metre of tubing supplied, so you can rely on predictable, professional results every single time you use this product in your RC car UK projects.

What's in the Box

• 1 metre of red heat shrink tubing, 5.0mm nominal diameter
• 1 metre of black heat shrink tubing, 5.0mm nominal diameter

Frequently Asked Questions

• What size heat shrink do I need for my RC wiring? — The LOGIC Heat Shrink sizing system quotes nominal expanded dimensions, meaning the inside diameter is approximately 20% larger than the stated size. This 5.0mm heat shrink can comfortably fit over wire up to 6mm in diameter, making it ideal for medium-gauge connections. The manufacturer provides a comprehensive sizing guide to help you select the correct diameter for your specific application—if you need it for thinner or thicker wire, the range extends from 1.5mm through to 90mm options.
• How much does heat shrink shrink down? — The LOGIC Heat Shrink features a standard 3:1 shrink ratio, meaning a 5.0mm tube will recover to approximately 2mm when heated to activation temperature, providing a very tight, secure seal around your connections that won't slip or move.
• Can I use this heat shrink near my brushless motor? — Yes, absolutely. The flame-retardant construction and wide operating temperature range from -45°C to 125°C make this heat shrink suitable for use near high-temperature components including brushless motors and speed controllers. The activation temperature of 125°C is hot enough to properly shrink the material but safe to work with using standard heat guns or lighters available in any RC workshop.
• Is this suitable for RC car wiring and cable protection? — This is an excellent choice for protecting and colour-coding cables and connections on any RC car, truck, or vehicle. The red and black colour options let you identify positive and negative circuits quickly, whilst the flexible, durable material withstands the vibrations and movements of active RC bashing and racing.
• What heat source should I use to activate this tubing? — Any standard heat source works well—a heat gun is ideal for professional results, but RC modellers commonly use cigarette lighters, match flames, or even careful use of a hot air soldering station. Apply heat evenly and gradually until the material shrinks snugly around the component, being careful not to overheat and damage nearby plastic components.
• Can I use this heat shrink in wet conditions or for waterproofing? — Whilst heat shrink provides excellent mechanical protection and insulation, it is not intended as a primary waterproofing solution. For waterproofing applications, use dedicated waterproof potting compounds or conformal coatings in conjunction with heat shrink for best results on submersible RC boats or waterproofed electronics.
• Will this heat shrink work on motor leads and esc connections? — Yes, this is one of the most common applications for heat shrink in RC hobbies. It provides excellent insulation and mechanical protection for motor lead connections and speed controller terminals, helping to prevent accidental short circuits and protecting against corrosion and vibration damage.
• How does this compare to other heat shrink products? — The LOGIC brand is recognised for consistent quality and reliable performance across the RC hobby community. This product offers professional-grade specifications including flame-retardant construction, low-smoke formulation, and a wide temperature operating range, all at an accessible price point that makes restocking your workshop inventory affordable.
