Flexible Glue Lined Heat Shrink Tube 3:1 4:1

The Volsun Flexible Glue Lined Heat Shrink Tube is a reliable and easy-to-use solution for protecting and insulating wires and cables. It comes in two shrink ratios: 3:1 and 4:1, which means the tube will shrink down to one-third or one-quarter of its original size when heated. This makes it perfect for fitting over connectors, joints, and cables of different sizes, providing a tight and secure seal.

Made with a special glue-lined inside, the Volsun heat shrink tube offers excellent waterproof and airtight protection. When heated, the glue melts and sticks firmly to the wires and cables, keeping out moisture, dust, and dirt. This not only protects the electrical connections but also helps to prevent corrosion and damage caused by water or other elements. The glue lining also helps improve the strength and durability of the tube, making it less likely to crack or break over time.

The tube is very flexible, which makes it easy to work with even in tight spaces or on curved surfaces. It bends easily without losing its shape or protective qualities, making it a great choice for automotive, marine, electronics, and home DIY projects. Whether you need to protect wires in a car engine, repair cables on a boat, or organize wiring in your home, Volsun’s heat shrink tubes provide a neat and professional finish.

To use the Volsun Flexible Glue Lined Heat Shrink Tube, simply slide it over the area you want to protect and apply heat with a heat gun or lighter. The tube will shrink tightly around the cable or connection, and the glue lining will bond to the surface, creating a strong seal. The high-quality material ensures fast and even shrinking without burning or melting, so you get a clean and smooth result every time.

The Volsun heat shrink tubes are available in various sizes to fit different cable diameters, making it easy to find the right tube for your project. They are also resistant to chemicals, abrasion, and extreme temperatures, ensuring long-lasting protection in harsh environments.

The Volsun Flexible Glue Lined Heat Shrink Tube 3:1 and 4:1 is a practical and trustworthy product for anyone needing to protect and insulate wires and cables. Its strong glue lining, flexible design, and wide size range make it a must-have tool for electrical work and repairs
