Dongfeng KL truck parts Compressor inlet air conditioning pipeline assembly 8108080-C3101

Built as a critical component for AC system efficiency, this pipeline assembly features industry-leading sealing and refrigerant retention capabilities. The pipeline uses seamless aluminum alloy tubes (6061-T6 grade) with a 1.5mm wall thickness, ensuring uniform refrigerant flow and minimal pressure drop (≤0.05MPa) at 1000rpm compressor speed. The fittings adopt O-ring face seal (ORFS) design with HNBR rubber seals (hardness 70 Shore A), which create a leak-tight connection that passes 24-hour pressure testing (1.5MPa nitrogen) with no detectable leakage. A protective nylon mesh sleeve covers the tube joints, preventing seal damage from vibration and ensuring the system maintains optimal refrigerant charge—avoiding AC cooling performance degradation (repair costs up to $600)

Engineered to withstand the harsh environment of the truck engine bay, the 8108080-C3101 assembly adopts comprehensive protective designs. The aluminum alloy tubes undergo electrophoretic coating (20μm thickness) followed by a PVDF powder coating (30μm thickness), achieving 2000-hour neutral salt spray resistance (ASTM B117) with no corrosion—ideal for humid coastal regions and snowy areas with road salt exposure. The outer insulation layer is made of cross-linked polyethylene (XLPE) with a 5mm thickness, resisting oil, coolant, and diesel contamination while providing thermal insulation to prevent refrigerant temperature rise. The assembly operates stably in temperatures from -40℃ to 120℃, adapting to extreme cold starts and high engine bay heat

Optimized to absorb engine vibration and prevent fatigue failure, the pipeline assembly integrates dedicated dampening features. The fixed brackets are equipped with EPDM rubber bushings that absorb vibration (10-500Hz) from the engine and chassis, reducing stress on the pipeline joints by 50%. The tube bends are precision-formed with a minimum bend radius of 30mm, avoiding material thinning and ensuring structural integrity under repeated vibration. A flexible polyester braid reinforcement covers high-stress areas (e.g., near the compressor), enhancing tensile strength by 40% and preventing tube kinking. These features enable the assembly to pass 300,000km vibration durability testing without cracks or leaks

This AC compressor inlet pipeline is designed for efficient installation and long-term cost savings for Dongfeng KL operators. The pre-assembled structure (tubes + fittings + brackets + insulation) allows a single technician to complete replacement in 90 minutes using only standard flaring tools and torque wrenches—no specialized bending or cutting required. The OE-compatible design ensures perfect alignment with the AC system, avoiding the misfit issues of aftermarket pipelines that cause leaks or pressure loss. The durable materials and corrosion-resistant coating extend service life to ≥500,000km—twice that of non-OE alternatives—reducing replacement frequency. By maintaining AC system efficiency, it lowers fuel consumption (AC load reduced by 15%) and avoids costly refrigerant recharge. Backed by a 2-year/250,000km Dongfeng warranty, it provides reliable performance and predictable maintenance expenses
