Dongfeng xinjiang truck parts intercooler Exhaust hose 1119124-T5GF01Y

Built to maximize the efficiency of the intercooler’s exhaust (cooled air delivery) to the engine, this hose features a precision-engineered inner structure. The ultra-smooth inner surface (Ra ≤ 0.6μm) minimizes airflow resistance, reducing pressure loss by 25% compared to aftermarket hoses with rough interiors. Its 80mm inner diameter ensures a maximum airflow rate of 420m³/h, perfectly matching the air demand of Dongfeng Xinjiang’s 480hp and 550hp engines. The 120° flexible bend is designed with a gradual curvature (radius 180mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.15bar pressure drop at full load). By delivering dense, cooled air to the combustion chamber, the hose enhances fuel combustion efficiency by 10%, boosting engine power output by 6-9% and reducing fuel consumption by 4-6% under heavy-haul conditions, while also lowering exhaust emissions

Engineered to endure the harsh operating conditions of intercooler systems—fluctuating temperatures and turbocharged pressure—the hose integrates a multi-layer composite structure for exceptional durability. The inner layer is made of high-performance fluorosilicone rubber, resistant to continuous temperatures of -45℃ to 280℃, capable of withstanding sudden cold starts in frigid regions and high-temperature airflow from the intercooler. The middle layer is a reinforced aramid fiber mesh, providing a working pressure rating of 1.8bar (peak pressure: 3.5bar) to resist expansion or burst during turbocharger surges. The outer layer is a heat-insulating EPDM rubber that reduces radiant heat transfer by 40%, protecting adjacent engine components from high-temperature damage. In durability tests, the hose maintains integrity through 60,000 thermal cycles (-35℃ to 260℃) and 120,000 pressure cycles, far exceeding standard rubber hose lifespans

Designed to resist the diverse threats of commercial truck operation—chemical corrosion, UV radiation, and mechanical wear—the hose delivers long-lasting reliability. The outer EPDM layer is impervious to diesel fuel, engine oil, road salt, and cleaning agents, preventing swelling, cracking, or degradation from accidental spills. It passes 2500-hour QUV UV testing with no surface brittleness or color fading, ensuring performance in sunny desert or high-altitude environments. The integrated stainless steel end rings and clamps (304-grade) resist rust and corrosion, maintaining a secure seal even after 1200-hour salt spray testing (ASTM B117). Additionally, the hose’s flexible structure absorbs engine and road vibrations (5-2500Hz, compliant with ISO 16750-3), reducing wear on intercooler and turbocharger connection points. This comprehensive protection ensures the hose functions reliably for over 7 years of heavy-duty use

Optimized for efficient maintenance in truck fleet operations, the hose features a user-friendly design that simplifies installation and replacement. It comes pre-assembled with adjustable stainless steel clamps and pre-coated high-temperature sealant (resistant to 300℃), eliminating the need for specialized crimping tools or additional sealants. The hose’s flexible structure (minimum bend radius 140mm) allows easy routing around engine bay components, even in tight spaces between the intercooler and turbocharger. Installation steps are straightforward: slide the hose over the intercooler and turbocharger flanges, align the mounting holes, and tighten the clamps with a standard socket wrench (recommended torque: 14-18N·m). The package includes 4 M8×20 galvanized bolts and a replacement gasket, while clear labeling (“INTERCOOLER END” and “TURBOCHARGER END”) prevents incorrect installation. A single technician can complete the replacement in 25 minutes or less, minimizing truck downtime and reducing maintenance costs for fleet operators
