Dongfeng Xinjiang truck parts air pipe 3506206-TCM302Y in stocked

Built to maximize airflow efficiency in the truck’s air-dependent systems, this pipe features a precision-engineered structure that minimizes flow resistance. The inner surface is polished to a roughness of ≤0.6μm, reducing pressure loss by up to 20% compared to standard air pipes—critical for maintaining consistent pressure in time-sensitive systems like air brakes. The inner diameter (22mm) is sized to match Dongfeng Xinjiang’s air flow rate requirements (100 L/min at 0.9MPa), ensuring rapid airflow delivery to components during peak demand (e.g., emergency braking or heavy clutch engagement). Pre-formed bends have a minimum radius of 35mm, avoiding kinking or constriction that could disrupt airflow velocity (maintained at 8-10 m/s for optimal performance). This optimized design shortens the air system’s response time—for example, reducing brake chamber activation delay by 0.2 seconds compared to restricted pipes—directly enhancing driving safety and operational efficiency

Engineered to withstand the truck air system’s operating pressure and prevent costly air leaks, the pipe delivers exceptional durability and sealing performance. It is constructed from a reinforced ethylene propylene diene monomer (EPDM) rubber composite with a polyester fiber mesh layer, offering a burst pressure rating of 3.5MPa—far exceeding the system’s maximum working pressure (1.0MPa). The pipe wall thickness (3mm) provides robust resistance to deformation under pressure spikes (e.g., during rapid brake application), while the end BSP connectors are equipped with dual-lip fluororubber (FKM) seals that create an airtight barrier. Each connector is pre-lubricated with air-system-compatible grease and torque-tested to 22N·m during production, ensuring zero leaks (verified via 24-hour pressure retention testing at 1.2MPa). The pipe also maintains its shape and seal integrity across extreme temperatures (-40℃ to 100℃), preventing pressure fluctuations caused by thermal expansion or contraction

Designed to endure the harsh conditions of the truck chassis—including road salt, mud, oil, and UV radiation—the air pipe features comprehensive resistance properties. The EPDM rubber composite resists degradation from contact with diesel fuel, engine oil, and brake fluid, avoiding swelling, hardening, or cracking that could compromise airflow. The outer surface is coated with a wear-resistant polyurethane layer, protecting against abrasion from road debris or friction with adjacent chassis components (tested to 500 cycles of rubbing against steel with no visible damage). It is also UV-stabilized, preventing brittleness or discoloration from prolonged sunlight exposure (withstood 1200 hours of UV testing without performance loss). In corrosion tests, the pipe showed no degradation after 1000 hours of salt spray exposure (per ASTM B117), ensuring reliability in coastal areas or winter roads with deicing salt. These features guarantee a service life of over 7 years in heavy-duty truck applications

Designed for hassle-free installation and long-term reliability, the air pipe offers flexibility and minimal maintenance needs. Its EPDM rubber material provides excellent flexibility (can bend up to 25° without permanent deformation), allowing slight adjustments during installation to align with chassis mounting points—eliminating the need for custom cutting or additional adapters. The package includes 6 stainless steel mounting clamps (compatible with Dongfeng Xinjiang’s chassis pre-drilled holes) and a tube of thread sealant for re-installation if required. Installation steps are straightforward: route the pipe along the chassis’ designated air system path, secure with clamps, and tighten the end connectors to the recommended torque. No specialized tools (e.g., pipe cutters or flaring tools) are needed, and a professional technician can complete installation in 25 minutes or less. The pipe’s smooth inner surface prevents debris buildup, reducing the need for cleaning or maintenance—lowering operational costs for fleet owners and truck operators
