Product Description: Immerse yourself in the world of advanced engineering with our 3:1, 4:1 double-walled tubing, meticulously crafted from a double-layered, halogen-free flame-retardant polyolefin and a robust hot melt adhesive. The exterior polyolefin layer boasts insulation, is halogen-free, and highly flame-resistant, while the interior hot melt adhesive layer excels in absorbing mechanical strain and ensures an impermeable seal. This exceptional product offers multiple functionalities including sealing, waterproofing, corrosion resistance, leakage prevention, multi-strand wiring harness support, and insulation. Ideally suited for an array of applications, it is perfect for wiring harnesses, marine wires, and metal pipes requiring superior sealing, insulation, bundling, and fixation. Features include a flame-retardant, UV-resistant, and wear-resistant outer layer, a reliable 3:1 shrink ratio, compliance with RoHS and REACH environmental protection standards, and customization options in black, orange, red, yellow, transparent, and more.
