Overview

The LOGIC Heat Shrink (1m Red/1m Black) 8.0mm O-LG-HS08 is an essential accessory for any RC enthusiast in the UK who wants to maintain professional-looking wiring installations. Whether you're building a custom RC car, setting up a brushless motor system, or maintaining your existing RC fleet, quality heat shrink tubing is indispensable for protecting connections and keeping your models looking neat and organised. This versatile twin-pack provides you with both red and black heat shrink tubing, allowing you to colour-code your electrical connections for easy identification of polarity and circuit function—a critical safety feature when working with LiPo batteries, ESCs, and motor connections.

Heat shrink tubing is far more than just a cosmetic upgrade; it's a fundamental protective component that safeguards your RC model's electrical integrity. By creating a durable, insulating sleeve around soldered joints, connector terminals, and cable terminations, heat shrink prevents corrosion, accidental short circuits, and physical damage that could compromise your RC setup. The 8.0mm diameter makes this product ideal for larger gauge wiring, thicker cable bundles, and terminal insulation work on medium to high-powered RC vehicles including RC buggies, RC trucks, and RC cars of all types. If you're serious about maintaining your RC hobby equipment to professional standards, this heat shrink pack belongs in your toolbox.

RC Model Shop stocks the full range of LOGIC Heat Shrink sizes for every application, from fine-gauge 1.5mm tubing for delicate signal wires through to substantial 15mm and larger clear sleeves for major cable runs. The 8.0mm size sits perfectly in the middle of the range, making it one of the most commonly used diameters in RC work. Combined with its flexible, flame-retardant construction and reliable shrink performance, this heat shrink delivers professional results every time.

Key Features

• Dual colour pack — red and black — This twin-pack includes 1 metre of red tubing and 1 metre of black tubing, allowing you to colour-code positive and negative connections or differentiate between different circuit branches, which is essential for safety and troubleshooting in complex RC electrical systems.
• 8.0mm nominal expanded diameter — The expanded diameter of 8.0mm is sized to comfortably fit over 8mm diameter wire and larger cable bundles, making it perfect for main power connections, motor leads, and thick silicone wire installations common in modern brushless RC vehicles.
• Flexible construction — The tubing remains flexible both before and after shrinking, allowing you to install it on pre-assembled wiring harnesses and around tight corners without cracking or splitting, unlike rigid alternatives.
• Flame-retardant properties — Built to resist ignition and limit flame spread, the flame-retardant formula protects against minor electrical arcing and provides an extra layer of safety around high-current connections in your RC car or truck.
• Low smoke if burned — Should the insulation ever be exposed to extreme heat, this material produces minimal smoke, reducing hazardous fume exposure compared to standard heat shrink tubing, a critical safety feature for indoor RC work and flight.
• Wide operating temperature range — With a rated operating range from -45°C to 125°C, this heat shrink remains stable in extreme conditions, protecting your connections whether your RC car is racing in summer heat or stored during cold winter months.
• Professional shrink ratio — The tubing features a 3:1 shrink ratio, meaning an 8.0mm expanded tube will recover to approximately 2.7mm after shrinking, creating a tight seal around your wiring without gaps or loose sections.
• Multiple applications — Ideal for cable and terminal insulation, cable marking and colour identification, mechanical protection of solder joints, and circuit identification on RC models of all types.

Technical Performance

The LOGIC Heat Shrink 8.0mm delivers consistent, reliable performance across all RC applications demanding durable wire insulation and protection. With an un-shrunk expanded diameter of 9.6mm and a shrunk recovered diameter of 3.2mm, this tubing creates a tight, professional seal around 8mm diameter wires and cable bundles typical of brushless motor leads and main battery connections in RC cars, trucks, and aircraft. The lay flat width measurement of 15.1mm indicates the width when the tube is squashed flat, which corresponds to the internal diameter multiplied by approximately 1.57—useful information when calculating how much material you need for complex harness work. The material construction combines flexibility with mechanical strength, resisting brittleness even after multiple heating and cooling cycles, making it ideal for RC models that see frequent assembly and disassembly during maintenance and upgrades. The shrink temperature of 125°C is achieved easily with a standard heat gun or even careful application of a heat source, activating the tubing's molecular memory to grip tightly around whatever it encloses. This performance profile makes the 8.0mm size perfectly suited for work on mid-range and high-power RC setups, from 4WD RC buggies to larger brushless RC trucks and even scaled RC aircraft requiring robust electrical installations.

What's in the Box

• 1 metre of red 8.0mm heat shrink tubing
• 1 metre of black 8.0mm heat shrink tubing

Frequently Asked Questions

• What size wire does 8mm heat shrink fit over? — The 8.0mm nominal expanded diameter is designed to fit comfortably over 8mm diameter wire. The inside diameter is approximately 20% larger than the nominal size, meaning it can accommodate wires up to about 8mm in diameter with a snug fit after shrinking. This makes it ideal for thick silicone power cables used in brushless RC cars and higher-voltage battery connections.
• How much does the heat shrink tube shrink when heated? — The LOGIC Heat Shrink features a 3:1 shrink ratio, so an 8.0mm expanded tube will recover to approximately 2.7mm after being heated to the shrink temperature of 125°C. This dramatic reduction creates an extremely tight seal around your wiring.
• What temperature do I need to heat this tubing to? — The shrink temperature is 125°C, which can be achieved using a standard heat gun available from any tool supplier or hobby shop. A heat gun provides even, controlled heating without damaging the wire insulation underneath. Take care not to overheat as this may damage surrounding components.
• Is this heat shrink suitable for outdoor RC models and waterproofing? — Whilst heat shrink provides excellent mechanical protection and insulation against accidental shorts, it is not a complete waterproofing solution on its own. For truly weatherproof installations on RC boats or outdoor RC vehicles, you may wish to combine heat shrink with silicone conformal coating or potting compound for maximum water resistance.
• Why do I need red and black heat shrink tubing? — The dual-colour pack allows you to colour-code your RC electrical connections for safety and easy identification. Red typically marks positive connections and black marks negative or ground connections, helping you quickly verify polarity when troubleshooting or making repairs to your RC vehicle.
• Can I use this heat shrink on solder joints? — Yes, this is one of the primary applications. The tubing slides over freshly soldered connections before shrinking, encapsulating the joint in a protective, insulating layer that prevents corrosion and accidental contact with adjacent components—essential practice when building custom battery connectors or motor lead extensions for RC models.
• Is this heat shrink suitable for beginners? — Absolutely. Heat shrink tubing is one of the most beginner-friendly ways to improve your RC work. Simply slide it onto your wire before soldering, solder the connection, then use a heat gun to shrink it in place. No special tools or skills required beyond basic RC assembly knowledge.
• What is the difference between this and smaller heat shrink sizes? — The 8.0mm size is significantly larger than the 2.0mm, 3.0mm, 4.0mm, 5.0mm, and 6.0mm options in the LOGIC range. Choose smaller sizes for delicate signal wires and servo leads; use 8.0mm and larger for main power cables, thick battery connectors, and bundle protection on larger RC vehicles.
