Product Description: Meticulously crafted, our 3:1 and 4:1 double-walled pipes boast a sophisticated structure composed of a dual-layer, halogen-free flame-retardant polyolefin with a robust hot melt adhesive. The exterior polyolefin layer is exquisitely insulating, halogen-free, and resists flames with ease. Inside, the hot melt adhesive adheres beautifully to buffer mechanical strain and ensures an impeccable seal. Experience multifunctional excellence with capabilities in sealing, waterproofing, corrosion prevention, and leakage resistance, while effortlessly managing multi-strand wiring harnesses and insulation needs. Ideal for a diverse range of applications, including marine wires and metal pipes requiring sealing, bundling, and fastening. Features: The outer layer is not just flame-retardant but also UV-resistant and wear-proof. Shrink ratio: A perfect 3:1. Adheres to stringent environmental protection standards: RoHS, REACH. Available in an array of colors: black, orange, red, yellow, transparent, and customizable options.
