- 2:1 Shrink Ratio: Our waterproof heat shrink tubing features a 2:1 shrink ratio, shrinking to one-third of its original size when heat is applied. This ensures enhanced resistance to stretching and vibration, along with increased tensile strength. - Dual-Wall Design: Engineered with two layers, our heat shrink tubing provides reliable and long-lasting protection. The inner layer is adhesive-lined, ensuring a waterproof and sealed connection. - Flame Retardant and Low Smoke: Made from polyolefin material, our heat shrink tubing is flame retardant and produces minimal smoke. The meltable adhesive inner layer withstands temperatures from -67 to 125 °C (-55 to 125 degrees Celsius). - User-Friendly Application: Our heat shrink tubing is designed for ease of use. Simply slide the tubing over the connection point and apply heat. In seconds, achieve professional-grade insulated connections. Applications: - Electrical Insulation: Perfect for insulating electrical wires and connections in automotive, marine, and household applications. - Cable Bundling: Ideal for organizing and protecting bundled cables to prevent wear and tear. - Sealing Connections: Use in plumbing or HVAC applications where waterproof seals are required for durability. Make the smart choice for your insulation and protection needs with our high-performance heat shrink tubing.
