Dongfeng Xinjiang truck parts Turbocharger intake hose 1119123-T5XF01Y

Built to maximize airflow efficiency from the air filter to the turbocharger, this hose features a precision-engineered inner structure. The ultra-smooth inner surface (Ra ≤ 0.7μm) minimizes airflow resistance, reducing pressure loss by 23% compared to aftermarket hoses with rough interiors. Its 70mm inner diameter ensures a maximum airflow rate of 350m³/h, perfectly matching the air demand of 460-520hp turbocharged engines. The 100° flexible bend is designed with a gradual curvature (radius 160mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.16bar pressure drop at full load). By delivering unobstructed, high-volume air to the turbocharger, the hose enhances compressor efficiency by 11%, boosting turbo response time by 9% and ensuring denser air enters the combustion chamber to improve power output and fuel economy

Engineered to endure the harsh operating conditions of turbocharger intake systems—fluctuating temperatures and boosted pressure—the hose integrates a multi-layer composite structure. The inner layer is made of high-performance fluorosilicone rubber, resistant to continuous temperatures of -42℃ to 270℃, capable of withstanding cold starts in frigid regions and high-temperature airflow from the engine bay. The middle layer is a reinforced aramid fiber mesh, providing a working pressure rating of 1.6bar (peak pressure: 3.2bar) to resist expansion or burst during turbocharger surges. The outer layer is a heat-insulating EPDM rubber that reduces radiant heat absorption by 45%, protecting the hose from engine block heat. In durability tests, it maintains integrity through 55,000 thermal cycles (-35℃ to 260℃) and 110,000 pressure cycles

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 2200-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 1100-hour salt spray testing (ASTM B117). Additionally, the hose’s flexible structure absorbs engine and road vibrations (5-2200Hz, compliant with ISO 16750-3), reducing wear on turbocharger and air filter connection points, ensuring 7+ years of heavy-duty use

Optimized for efficient maintenance in truck fleet operations, the hose features a user-friendly design. 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 130mm) allows easy routing around engine bay components, even in tight spaces between the air filter and turbocharger. Installation steps: slide the hose over the flanges, align mounting holes, and tighten clamps with a standard socket wrench (13-16N·m torque). The package includes 4 M7×18 galvanized bolts and a replacement gasket. Clear labeling (“AIR FILTER END”/“TURBO END”) prevents misinstallation, and a single technician can complete replacement in 22 minutes or less, minimizing truck downtime
