Fastrax 6.4mm Heatshrink Tubing Red Black 10cm Pack of 4 FAST97

Overview

The Fastrax 6.4mm x 10cm Heatshrink Red/Black (4) FAST97 is an essential electrical accessory for RC enthusiasts across the UK who demand professional-quality cable management and protection. Whether you're building a custom RC car, maintaining a brushless RC vehicle, or working on electrical repairs for your RC hobby, heatshrink tubing is an indispensable component in any RC modeller's toolkit. This pack contains four individual pieces of premium heatshrink tubing, each measuring 10 centimetres in length with a 6.4mm internal diameter, making it perfectly suited for protecting and insulating medium-gauge battery connectors, motor leads, and servo cables on everything from RC buggies and RC crawlers to RC trucks and racing vehicles.

Manufactured by Fastrax, a trusted name in RC accessories and spare parts, this heatshrink tubing is available in both vibrant red and professional black colours, giving you versatility for colour-coding your electrical connections or matching your RC model's aesthetic. For anyone building or maintaining electric-powered RC cars and RC vehicles in the UK, having quality heatshrink tubing on hand is a must. The dual-colour pack allows you to organize your battery connections by polarity or functionality, a practice that serious RC competitors and weekend bashers alike appreciate when troubleshooting or upgrading their setups.

Heatshrink tubing serves as both a protective barrier and a professional finishing touch to any electrical installation on RC models. When heated (typically with a heat gun or soldering iron), the material shrinks tightly around your connectors, creating a waterproof seal that protects against dust, moisture, and accidental shorts. This is particularly important for outdoor RC enthusiasts who run their vehicles in challenging terrain or wet conditions. The 6.4mm diameter makes this product ideal for standard XT90, EC3, and similar battery connectors commonly found on modern RC vehicles.

Key Features

• Dual-Colour Design — Each pack includes both red and black heatshrink tubing, allowing you to colour-code positive and negative connections or match your RC model's colour scheme, making electrical work cleaner and more professional-looking.
• 6.4mm Internal Diameter — This size perfectly accommodates standard battery connectors and motor leads used on most electric RC cars, RC buggies, and RC crawler vehicles, ensuring a snug fit that shrinks evenly when heated.
• 10cm Length Per Piece — Each individual length provides ample material for covering connectors with room to spare, and four pieces per pack means you'll have multiple applications covered whether you're working on one vehicle or maintaining several RC models.
• Heat-Activated Shrinking — Simply apply heat from a heat gun, hair dryer, or soldering iron and the tubing contracts tightly around your connections, creating a professional seal that's both aesthetic and functional.
• Reliable Brand Quality — Fastrax is a recognized manufacturer of RC spare parts and accessories, and this heatshrink meets the quality standards expected by RC enthusiasts and professionals across the UK RC hobby community.
• Waterproof and Protective — Once shrunk into place, the tubing creates a protective barrier against moisture, dirt, and accidental contact that could cause electrical shorts or damage to your RC vehicle's electronics.
• Easy to Use — No special tools required beyond a simple heat source; simply slide the tubing over your connector and apply gentle heat until it shrinks into place, making this suitable for beginners and experienced modellers alike.

Technical Performance

The Fastrax 6.4mm x 10cm Heatshrink tubing is engineered from high-quality polymer material that exhibits excellent heat-shrinking characteristics. When exposed to heat (typically between 100-150°C), the tubing contracts uniformly around whatever it's wrapped around, creating a tight, professional seal. The 6.4mm internal diameter before heating makes this product ideal for protecting standard battery connectors found on brushless RC cars, RC crawlers, and electric RC vehicles throughout the UK market. The tubing maintains its integrity and flexibility even after shrinking, meaning your electrical connections won't become brittle or prone to cracking over time. Each piece measures exactly 10 centimetres in length, providing sufficient coverage for single or multiple connector applications. The dual-colour approach (red and black) isn't merely cosmetic; it represents professional electrical practice where different colours indicate different polarities or circuit functions, reducing the risk of wiring mistakes when building or maintaining complex RC setups. For modellers working with LiPo batteries, brushless motors, and modern RC electronics, this heatshrink offers the protection needed to prevent shorts and extend the lifespan of expensive components. The material resists UV degradation and maintains its protective qualities through numerous charge-discharge cycles and outdoor use.

Frequently Asked Questions

• What size battery connectors does 6.4mm heatshrink fit? — The 6.4mm internal diameter is specifically designed to fit standard XT90, EC3, and similar medium-gauge battery connectors commonly used on modern electric RC cars, RC buggies, and brushless RC vehicles. Always measure your connector diameter before use to ensure a proper fit.
• How do I use heatshrink tubing on my RC vehicle? — Slide the heatshrink tubing over your connector or wire, position it where you want it sealed, then apply gentle heat using a heat gun, soldering iron, or even a lighter held at a safe distance. The material will shrink uniformly around your connector within seconds, creating a tight, professional seal. Avoid overheating as this can damage the connector or surrounding components.
• Is heatshrink tubing waterproof? — Once properly shrunk into place, heatshrink tubing creates a protective barrier that resists moisture and dust ingress. However, it is not a complete waterproof solution on its own; it should be used as part of a broader weatherproofing strategy, especially for RC vehicles intended for wet-weather operation.
• What's the difference between red and black heatshrink? — Functionally, both colours perform identically in terms of electrical protection and heat-shrinking properties. The colour difference allows you to colour-code your electrical connections following standard practice where red indicates positive and black indicates negative, making troubleshooting and maintenance easier on your RC model.
• Can I use heatshrink on my RC crawlers and rock crawlers? — Absolutely. Whether you're building a rock crawler, an RC buggy, or any other type of electric RC vehicle, heatshrink tubing provides essential protection for electrical connections, particularly important if your crawler operates in dusty or wet terrain.
• Is this suitable for beginners? — Yes, heatshrink tubing is one of the easiest electrical components to use and is perfect for beginners learning RC vehicle assembly and maintenance. It requires no soldering skills and only needs a basic heat source, making it an ideal starting point for understanding cable protection and professional electrical work on RC models.
• How long does each piece last? — Once properly shrunk and sealed, each piece of heatshrink tubing will last indefinitely as part of your permanent electrical connection. The material is designed to resist UV degradation and environmental wear, making it suitable for both indoor and outdoor RC use.
