5mm Black Polyolefin Heat Shrink Tubing 6M 19.7ft for Electrical Wire Insulation and Flexible Sealing

Heat Shrinkable Tube made from polyolefin for reliable electrical insulation and cable protection. Designed for general wiring, cable , and connector sealing where a 2 to 1 shrink ratio is required. Key benefits Secure insulation for wires and splices, reducing exposure of bare conductors and preventing short circuits. Compact, tight fit after shrinking to protect connections from moisture, abrasion, and mechanical strain. Long continuous length reduces the need for multiple pieces when working on wiring harnesses or long runs. What makes it stand out Material: Polyolefin for flexible, durable performance. rated voltage: Suitable for systems up to 660V. temperature tolerance: Rated to 125C for demanding thermal environments. Precise shrink ratio: 2 to 1 for predictable sizing from original diameter to finished diameter. Long length: Approximately 6 m for multiple uses from a single supply. Key specifications Product name: Heat Shrinkable Tube Material: Polyolefin Rated voltage: 660V Temperature level: 125C Flammability: VW1 Shrink ratio: 2 to 1 Diameter before shrinking: 5 mm / 0.196 inches Diameter after shrinking: 2.5 mm / 0.098 inches Length approximate: 6 m / 236.2 inches / 19.7 feet Color: Black Typical applications Electrical wiring and cable : Insulate splices and restore protective covering after soldering or crimping. Automotive and marine installations: Protect sensors, connectors, and exposed wiring from abrasion and moisture in vehicles and boats. Electronics and DIY projects: Bundle wires, secure strain relief, and insulate connectors on hobby and professional assemblies. Usage tips Cut to length before heating to accommodate overlap at joints. Heat evenly with a heat gun or controlled flame source suitable for polyolefin until the tube shrinks uniformly to the final diameter. Allow to cool before handling to ensure a secure fit. Compatibility and performance notes Use on cables and connectors where the final diameter after shrinking is at or below 2.5 mm. Suitable for systems with voltages up to 660V and continuous temperatures up to 125C. Black color provides a neutral, professional appearance and UV resistance in many applications. This heat shrinkable tube offers a practical, durable solution for insulating and protecting electrical connections and cables in a wide range of applications.
