During vehicle operation, wiring harnesses endure prolonged exposure to high temperatures, insulation challenges, vibrations, low temperatures, and more. Ordinary protective conduits are prone to aging, cracking, and deformation under such conditions, shortening their service life. PP flame-retardant conduit maintains stability within a temperature range of -20°C to 100°C, with customizable flame-retardant ratings. For extended longevity, choose branded products. Harnesses utilizing new modified materials ensure quality, safeguarding circuit safety at the source. This reduces maintenance costs and safety hazards caused by wiring failures. LEINUOER, a premium brand and source manufacturer, offers products certified with RoHS compliance and full product coverage, delivering superior solutions for automotive wiring harness protection.
