3:1 heat shrink tubing - Ø 7.9 mm and length 4 m, heat shrink tubing per meter, waterproof insulating tape and heat shrink tubing for joining electrical cables, 7 diameter options (

General Description: This 3:1 heat shrink tubing, 7.9 mm in diameter and 4 m long, provides effective protection for electrical cable connections. Thanks to its 3:1 shrink ratio, it reduces to three times its original diameter, ensuring a perfect seal. Made from high-quality, flame-retardant polyolefin, this tubing offers excellent electrical insulation, corrosion resistance, and increased durability. Specifications: Diameter: 7.9 mm, Length: 4 m, Shrink Ratio: 3:1, Material: Flame-retardant polyolefin. Compatibility and Accessories: Available in 7 different diameters: 3.2 mm, 7.9 mm, 9.5 mm, 15 mm, 19.1 mm, 30 mm, and 39 mm. Available lengths: 2 m, 4 m, and 6 m. Installation: To apply the heat shrink tubing, simply wrap the exposed wire section with the tubing and heat it with a soldering iron or heat gun. This ensures the internal adhesive bonds securely to the cable, creating a watertight seal. This tubing is ideal for protecting electrical cable connections, providing waterproof and moisture-resistant insulation. It is easy to apply and shrinks in seconds.
