Dongfeng xinjiang truck parts Connect the compressor and condenser air conditioning pipe assembly 8108010-KXR602Y

Built to enhance air conditioning performance, this pipe assembly features a precision-engineered structure that minimizes refrigerant flow resistance. The inner surface of the 6061-T6 aluminum pipe is polished to a roughness of ≤0.6μm, reducing pressure drop by up to 20% compared to generic pipes—ensuring efficient transfer of high-pressure refrigerant from the compressor to the condenser. The pre-formed bends have a minimum radius of 35mm, preventing kinking or constriction that could disrupt flow velocity (maintained at 1.3-1.6m/s, the optimal range for heat exchange). Additionally, the pipe’s length and diameter are matched to the compressor’s displacement (e.g., 12cc/rev for X7 models), avoiding refrigerant stagnation and ensuring rapid heat dissipation in the condenser. This optimized flow enables the AC system to cool the cab from 40℃ to 25℃ in 7 minutes and maintain stable temperature even during idle or heavy-haul operations

Engineered to withstand the extreme pressure of truck AC systems, the pipe assembly delivers exceptional pressure resistance and sealing performance. The 6061-T6 aluminum pipe (wall thickness: 2mm) has a burst pressure rating of 40MPa—far exceeding the system’s maximum working pressure (20-24MPa for R134a). The flared O-ring fittings are equipped with fluororubber (FKM) seals, which offer superior resistance to refrigerant, oil, and high temperatures (up to 200℃) compared to standard NBR seals. Each fitting undergoes a 24-hour pressure retention test at 28MPa during production, ensuring zero refrigerant leakage. The assembly also includes a vibration-damping sleeve at the compressor connection, reducing wear on the fitting from engine vibration and preventing seal degradation over time. This robust design eliminates AC performance loss, avoids costly refrigerant refills, and extends the system’s service life

Designed to endure the harsh conditions of truck engine bays (heat, oil mist, humidity, road debris), the pipe assembly features a multi-layer protective system. The aluminum pipe undergoes a chromate conversion coating (8μm) for base corrosion resistance, followed by a high-temperature epoxy powder coating (90μm) that resists scratches, oil, and UV radiation. This coating system passes 1000-hour salt spray testing (per ASTM B117) with no red rust, ensuring durability in coastal areas or winter roads with deicing salt. The external EPDM rubber sleeve insulates the pipe from engine heat (operating temperature range: -45℃ to 160℃) and protects it from abrasion against adjacent components. All metal fittings are zinc-nickel plated (10μm thickness) to prevent rust, and the assembly is tested for resistance to engine coolant and lubricating oil spills—guaranteeing a service life of over 7 years

Designed for efficient installation, the pipe assembly undergoes CNC bending and precision machining to achieve strict dimensional accuracy (length tolerance: ±2mm, bend angle tolerance: ±1°). The pre-formed bends and fixed length eliminate on-site pipe modification, while the fittings are pre-lubricated with refrigerant-compatible grease for easy connection. The package includes 2 stainless steel lock nuts, 4 spring washers, and a tube of high-temperature thread sealant (matching Dongfeng Xinjiang’s OE specification). Installation steps are straightforward: align the pipe’s fittings with the compressor outlet and condenser inlet, hand-tighten the lock nuts, then torque to 26-28N·m with a torque wrench. No specialized tools (e.g., pipe benders or flaring tools) are required, and a professional technician can complete installation in 25 minutes or less. The assembly’s lightweight design (2.1kg) simplifies handling, and the compact bends ensure easy access in tight engine bays—reducing labor costs and minimizing truck downtime for commercial operators
