🧩 Product Overview: Our 4:1 Heat Shrink Tubing is available in lengths of 1 meter, 2 meters, and 3 meters, ensuring you have the right amount for your projects. This versatile tubing is ideal for a variety of applications, such as electrical insulation, wire bundling, and components protection. It provides both durability and flexibility, making it a reliable choice for professionals and DIY enthusiasts alike.

🔒 Specifications: The tubing comes in a range of diameters, including 4mm, 6mm, 8mm, 12mm, 16mm, 20mm, 24mm, 32mm, 40mm, and 52mm, with a contraction ratio of 4:1. This means that the tubing will shrink to one-fourth of its original diameter when heat is applied, allowing for a snug and secure fit around various substrates and components.

💍 Design and Material: Crafted from high-quality materials, our heat shrink tubing features a double-wall construction, providing an additional layer of protection. The inner layer includes an adhesive that activates upon heating, ensuring a tight seal that prevents moisture, dust, and other contaminants from entering and damaging your connections. The outer layer is designed to withstand harsh conditions, making it suitable for both indoor and outdoor applications.

🧩 Usage Guidance: When selecting the appropriate size of heat shrink tubing, customers are encouraged to refer to the specified diameter of the tube. It is important to note that the tubing is shipped in a folded state for efficient packaging. Customers should not use the width of the folded product as a reference for the diameter, as this may lead to incorrect sizing for their intended application. Optimal performance is achieved when the tubing is used as intended and sized accordingly.
