Dongfeng Xinjiang truck spare parts air pipe 3506202-T8M300Y

Built to ensure smooth, efficient airflow in the truck’s air system, this pipe features a precision-engineered internal structure that minimizes flow resistance. The inner surface is polished to a roughness of ≤0.8μm, reducing pressure loss by up to 15% compared to standard air pipes—critical for maintaining stable pressure in air-dependent systems like air brakes or air suspension. The pipe’s inner diameter (26mm) is sized to match Dongfeng Xinjiang’s air system flow rate requirements (120 L/min at 0.9MPa), ensuring sufficient airflow to power components even during peak demand (e.g., simultaneous brake application and suspension adjustment). Pre-formed bends have a minimum radius of 40mm, avoiding kinking or constriction that could disrupt airflow. This optimized design ensures the air system responds quickly—for example, reducing brake pedal travel time by 0.3 seconds compared to restricted pipes—enhancing driving safety

Engineered to withstand the truck air system’s operating pressure and prevent air leaks, the pipe delivers exceptional durability and sealing performance. It is made of high-density polyethylene (HDPE) with reinforced nylon layers, offering a burst pressure rating of 3.0MPa—far exceeding the system’s maximum working pressure (1.0MPa). The pipe wall thickness (3mm) provides robust resistance to deformation under pressure spikes, while the end NPT connectors are equipped with nitrile rubber (NBR) O-rings that create a tight seal against air leakage. Each connector is pre-coated with thread sealant (compatible with air system oils) and torque-tested to 25N·m during production, ensuring zero leaks (tested to 24-hour pressure retention at 1.2MPa). The pipe also resists expansion or contraction under temperature changes (-40℃ to 80℃), maintaining a consistent seal and preventing pressure fluctuations. This leak-proof design eliminates air loss, reducing the air compressor’s workload and extending its service life

Designed to endure the harsh environment of the truck chassis—including oil, road salt, mud, and UV radiation—the air pipe features comprehensive resistance properties. The HDPE-nylon composite material resists degradation from contact with diesel fuel, engine oil, and brake fluid, avoiding swelling or cracking that could compromise airflow. It is also UV-stabilized, preventing brittleness or discoloration from prolonged exposure to sunlight (tested to 1000 hours of UV radiation with no performance loss). The pipe’s outer surface is resistant to abrasion from road debris or contact with adjacent chassis components, maintaining structural integrity even after years of use. In corrosion tests, the pipe showed no degradation after 800 hours of salt spray exposure (per ASTM B117), ensuring durability in coastal areas or winter roads with deicing salt. These features guarantee the pipe maintains functionality for over 6 years in heavy-duty truck applications

Designed for easy installation and long-term reliability, the air pipe offers flexibility and low maintenance requirements. Its HDPE-nylon material provides moderate flexibility (bend angle up to 15° without permanent deformation), allowing slight adjustments during installation to align with chassis mounting points—eliminating the need for custom cutting or additional fittings. The package includes 4 stainless steel mounting clips (compatible with Dongfeng Xinjiang’s chassis pre-drilled holes) and a tube of thread sealant for re-installation if needed. Installation steps are straightforward: route the pipe along the chassis’ air system path, secure with clips, and tighten the end connectors to the recommended torque. No specialized tools (e.g., pipe cutters or flaring tools) are required, and a technician can complete installation in 30 minutes or less. The pipe’s smooth inner surface prevents debris buildup, reducing the need for cleaning or maintenance—further lowering operational costs for truck owners
