Product Description
The Heat Shrink Tubing 5mm Black is a professional-grade insulation and protection accessory designed for electronics work, wiring harnesses, heavier gauge solder joints, and custom cable management. Featuring a 5mm pre-shrink diameter that contracts securely upon the application of heat, this flexible polyolefin tubing provides reliable electrical insulation, mechanical abrasion protection, and robust strain relief for multi-wire bundles and power connections.
Essential for insulating larger splices, protecting terminal connections, and organizing custom robotics or power wiring, this durable heat shrink tubing combines a clean professional finish with easy application.
🔥 Heating Tip: Use a heat gun or a controlled lighter flame moving evenly back and forth along the tubing to shrink it uniformly without scorching or melting the plastic.
Technical & Architectural Highlights
5mm Initial Diameter: Perfectly sized for covering thicker wire splices, multi-wire bundles, ring terminals, or small component housings.
2:1 Shrink Ratio: Contracts securely around wires and components upon heating for a snug, permanent, and insulating fit.
Flexible Polyolefin Material: Provides reliable electrical insulation, flame resistance, and mechanical protection against wear and tear.
Professional Black Finish: Standard black color offers a clean, discreet appearance for finished commercial or DIY electronic assemblies.
