2 Times Black Heat Shrink Tube Kit: Flame Retardant and Waterproof Cable Repair

Whether you are repairing a damaged USB cable, insulating electrical connections, or organising home wiring, this 2 Times Black Heat Shrink Tube Kit offers a practical, reliable solution. Made from flame-retardant and waterproof polyolefin, these tubes shrink to half their original diameter, creating a snug, protective layer around cables and wires. The kit includes round and flat profiles to suit various cable shapes, providing flexibility for hobbyists, electricians, and DIY enthusiasts alike. With UL certification and ISO9001 manufacturing, it meets recognised safety and quality standards.

Features and Construction

Each tube in this kit is engineered for effective insulation and protection. The 2:1 shrink ratio ensures a tight fit, while the material properties deliver both electrical safety and physical durability.

Material and Build

The tubing is made from polyolefin, a material chosen for its excellent electrical insulation and resistance to heat. It is flame-retardant and waterproof, reducing fire risk and protecting against moisture. The dielectric strength of 15KV/mm and compressive strength of 10.4 MPa confirm its suitability for insulating live connections and withstanding moderate pressure.

Size and Practical Fit

The tubes shrink at a minimum temperature of 84°C and a maximum of 120°C, requiring only a standard heat gun or hair dryer. They operate across a broad temperature range of -55°C to 125°C, making them usable in cold environments and near hot components. With both round and flat profiles, they can adapt to cylindrical cables or ribbon-style wires.

Uses and Placement

This heat shrink tubing is designed for a wide range of electrical and cable-related tasks, from simple repairs to organised installations.

Event or Professional Use

Electricians and technicians can use this kit for on-site cable repairs, splicing, or terminations. The UL certification adds confidence for professional environments where safety standards are required. The flat profile is particularly useful for repairing or insulating microphone cables, USB leads, or other multi-conductor wires.

Everyday Home Use

Home users will find it ideal for fixing frayed charging cables, computer wires, or appliance cords. The black colour blends in with most cables, keeping repairs tidy. The kit includes enough tubing for multiple small projects, though exact quantities and sizes are not specified, so users should assess their needs beforehand.

Benefits and Buying Value

This kit offers practical advantages that save time and materials while ensuring safety.

Reuse and Low Maintenance

Once shrunk, the tubing stays firmly in place without adhesives or tape, reducing the need for future maintenance. The waterproof and flame-retardant properties mean it can handle occasional exposure to moisture or heat without degrading.

Why Choose This Product

You get a UL-certified, ISO9001-manufactured product with clear technical specifications. The 2:1 shrink ratio and wide temperature range cover most standard cable repairs. The combination of round and flat profiles increases versatility without having to buy separate kits.
