Length and purpose: Length 5M. This inner line sponge tube measures 1.5m/5.0ft and is designed to meet your needs for sound absorption and ease of use. Compatibility: Suitable for tubes, brake tubes, and fuel pipes with an outer diameter of 6mm/24 inches. Material and hardness: Made from density sponge material, providing sufficient hardness with strong folding resistance and durability for longlasting performance. Flexibility: Flexible frame shell lets the tube bend in any direction without deformation, enabling adaptability for various installations. Use scenario 1: In automotive applications, install on brake lines or nearby tubing to dampen noise and reduce movement in the engine bay. Use scenario 2: For tight routing of fuel pipes or other smalldiameter lines in compact vehicles or machinery, providing routing flexibility and vibration absorption. Use scenario 3: In custom builds or DIY projects where tubing must navigate multiple bends while maintaining structural integrity and sound absorption.
