Original Dongfeng Xinjiang truck parts air pipe 3506208-T8M300Y

Built to support the truck’s air-dependent systems (e.g., air brakes, air suspension), this original air pipe features a factory-engineered internal design that minimizes airflow resistance. The inner surface is polished to a roughness of ≤0.6μm via Dongfeng Xinjiang’s proprietary machining process, reducing pressure loss by up to 18% compared to non-original alternatives. Its inner diameter (24mm) is sized to match the X7/X5 air system’s flow rate demand (110 L/min at 0.9MPa), ensuring sufficient airflow to power brakes or suspension even during peak load (e.g., heavy hauling on slopes). Pre-formed bends have a minimum radius of 38mm—strictly following factory geometric standards—to avoid kinking or constriction. This optimization ensures the air system responds rapidly: for example, cutting brake chamber activation time by 0.25 seconds, directly enhancing driving safety in emergency scenarios

Engineered to withstand the truck air system’s operating pressure (0.8-1.0MPa) and meet Dongfeng Xinjiang’s strict durability standards, the pipe delivers exceptional pressure resistance and leak-proof performance. It is constructed from original-grade HDPE (high-density polyethylene) with a reinforced nylon core, offering a burst pressure rating of 3.2MPa—3x higher than the system’s maximum working pressure. The pipe wall thickness (3mm) is uniformly extruded via factory precision equipment, preventing deformation under pressure spikes. End connectors are equipped with original nitrile rubber (NBR) O-rings, pre-sealed with Dongfeng Xinjiang’s proprietary thread sealant during production. Each pipe undergoes a 24-hour factory pressure test (1.2MPa retention) to ensure zero leaks—avoiding air loss that could lead to brake delay or compressor overwork, common issues with non-original pipes

Made with Dongfeng Xinjiang’s factory-specified materials, the air pipe resists harsh chassis conditions—road salt, mud, oil, and UV radiation—far better than generic alternatives. The HDPE-nylon composite is resistant to diesel fuel, engine oil, and brake fluid, avoiding swelling, cracking, or chemical degradation (tested to 500 hours of immersion in diesel with no performance loss). Its outer surface is coated with original UV-stabilized resin, preventing brittleness from prolonged sunlight exposure (withstood 1500 hours of UV testing per Dongfeng Xinjiang standards). The pipe also resists abrasion from road debris or chassis friction, maintaining structural integrity after 1000 cycles of rubbing against steel components. In salt spray tests (ASTM B117), it shows no corrosion after 1200 hours—ensuring reliability in coastal areas or winter roads with deicing salt, matching the truck’s original service life (over 7 years)

Designed for hassle-free installation and long-term reliability, this original air pipe simplifies maintenance while ensuring factory-level fit. Its material offers moderate flexibility (15° bend without permanent deformation), aligned with Dongfeng Xinjiang’s chassis mounting tolerances—allowing slight adjustments during installation without cutting or adapters. The package includes original-matching stainless steel mounting clips (4 pieces) and a tube of factory-approved thread sealant, ensuring compatibility with the X7/X5’s pre-drilled chassis holes. Installation steps follow the brand’s service manual: route the pipe along the factory-designated path, secure with clips, and torque connectors to 24N·m (factory-specified value). No specialized tools are needed, and a technician can complete installation in 25 minutes—30% faster than non-original pipes that require modifications. The smooth inner surface prevents debris buildup, reducing maintenance frequency and lowering long-term operational costs
