Dongfeng xinjiang truck parts Connect the compressor outlet air conditioning pipe assembly 8108010-KDS601Y

Built to maximize air conditioning performance, this pipe assembly features a smooth internal structure and precision-formed bends that minimize refrigerant flow resistance. The inner surface of the aluminum pipe is polished to a roughness of ≤0.8μm, reducing pressure drop by up to 15% compared to generic pipes—ensuring efficient transfer of high-pressure refrigerant from the compressor to the condenser. The pre-formed bends are designed with a minimum radius of 30mm, preventing kinking or constriction that could hinder flow. Additionally, the pipe’s length and diameter are calibrated to match the compressor’s displacement, maintaining optimal refrigerant velocity (1.2-1.5m/s) for heat exchange efficiency. This optimized flow ensures the AC system cools the cab quickly (reaching 24℃ from 38℃ in 8 minutes) and maintains stable temperature even during long-haul driving in high-temperature environments

Engineered to withstand the extreme pressure of truck AC systems, the pipe assembly features a high-strength aluminum alloy (6061-T6) structure with a burst pressure rating of 35MPa—exceeding the system’s maximum working pressure (18-22MPa for R134a). The pipe wall thickness (2mm) provides robust resistance to deformation under pressure spikes, while the flared O-ring fittings are equipped with nitrile rubber (NBR) seals that offer excellent refrigerant resistance. Each fitting is torque-tested to 25N·m during production, ensuring a tight seal that prevents refrigerant leaks (tested to 24-hour pressure retention at 25MPa). The assembly also includes a protective sleeve at the compressor connection point, reducing vibration-induced wear on the fitting. This leak-proof and pressure-resistant design eliminates AC performance loss and avoids costly refrigerant refills

Designed to endure the harsh conditions of truck engine bays (heat, oil mist, humidity, road debris), the pipe assembly features comprehensive protective treatments. The aluminum pipe undergoes a multi-layer coating process: a chromate conversion layer (5μm) for corrosion resistance, followed by a powder coating (80μm) that resists scratches, oil, and UV radiation. This coating system passes 800-hour salt spray testing (ASTM B117) with no corrosion, ensuring durability in coastal areas or winter roads with deicing salt. The external protective sleeve (EPDM rubber) shields the pipe from abrasion against adjacent components and insulates it from engine heat (operating temperature range: -40℃ to 150℃). All metal fittings are zinc-plated to prevent rust, and the assembly is tested for resistance to engine oil and coolant spills—guaranteeing a service life of over 6 years

Designed for efficient installation, the pipe assembly undergoes CNC bending and precision machining to achieve strict dimensional accuracy. The pre-formed bends and fixed length eliminate on-site adjustments, while the flared fittings are pre-lubricated for easy connection. The package includes 2 stainless steel lock nuts, 4 flat washers, and a tube of thread sealant that matches the factory specifications. Installation steps are straightforward: align the pipe’s fittings with the compressor outlet and condenser inlet, hand-tighten the lock nuts, then torque to 22-25N·m with a torque wrench. No specialized tools (e.g., pipe benders) are required, and a professional technician can complete installation in 30 minutes or less. The assembly’s lightweight design (1.8kg) simplifies handling, and the compact bends ensure easy access in tight engine bays. This user-friendly design reduces labor costs and minimizes truck downtime—critical for commercial operators relying on functional AC for driver comfort
