Dongfeng Xinjiang truck parts intercooler intake hose 1119121-T5KE03Y

Built to maximize the efficiency of heated turbocharged air delivery to the intercooler, this hose features a precision-optimized internal structure. The inner surface undergoes a nano-coating treatment, achieving a roughness of Ra ≤ 0.5μm to minimize airflow resistance—reducing pressure loss by 24% compared to aftermarket hoses with rough, unprocessed interiors. Its 73mm inner diameter ensures a maximum airflow rate of 370m³/h, perfectly matching the air demand of 520-560hp high-performance engines. The 110° elbow is designed with a gradual curvature (radius 170mm) to avoid airflow turbulence, maintaining consistent pressure (≤0.14bar pressure drop at full load). By delivering unobstructed, high-volume air to the intercooler, the hose enhances heat dissipation efficiency by 13%, ensuring intake air temperature is reduced to 45-55℃ (from 180-220℃ post-turbo), boosting fuel combustion efficiency by 9% and reducing fuel consumption by 4-6% under heavy-haul conditions

Engineered to endure the harsh operating conditions of turbocharged intercooler systems—fluctuating high temperatures and boosted pressure—the hose integrates a four-layer composite structure for exceptional durability. The inner layer is made of high-purity fluorosilicone rubber, resistant to continuous temperatures of -45℃ to 280℃, capable of withstanding sudden cold starts in -35℃ northeast China winters and high-temperature airflow from the turbocharger. The second layer is a high-strength aramid fiber braid (24×24 weaving density), providing a working pressure rating of 1.7bar (peak pressure: 3.4bar) to resist expansion or burst during turbocharger surges (common in mountain climbing scenarios). The third layer is a heat-insulating ceramic fiber mat that reduces radiant heat transfer by 50%, while the outer layer is a flame-retardant EPDM rubber (UL94 V-0 rating) that shields against engine bay heat. In durability tests, the hose maintains integrity through 60,000 thermal cycles (-30℃ to 260℃) and 120,000 pressure cycles (0-1.8bar), far exceeding the 30,000-cycle lifespan of standard rubber hoses

Designed to resist the diverse threats of commercial truck operation—chemical corrosion, UV radiation, and mechanical wear—the hose delivers long-lasting reliability for over 7 years of heavy-duty use. The outer EPDM layer is impervious to diesel fuel, engine oil, road salt, and cleaning agents (e.g., alkaline washer fluid), preventing swelling (volume change ≤3% after 72-hour immersion) or cracking. It passes 2500-hour QUV UV testing (ASTM G154) with no surface brittleness, color fading, or loss of flexibility, ensuring performance in sunny desert regions (e.g., Taklamakan) or high-altitude areas (Qinghai-Tibet Plateau). The integrated stainless steel end collars and clamps (304-grade) resist rust and corrosion, maintaining a secure seal even after 1200-hour salt spray testing (ASTM B117) with no red rust formation. Additionally, the hose’s flexible structure absorbs engine and road vibrations (5-2500Hz, compliant with ISO 16750-3), reducing wear on turbocharger and intercooler connection points by 60%

Optimized for efficient maintenance in truck fleet operations, the hose features a user-friendly pre-assembled design that reduces installation time by 40%. It comes with pre-installed adjustable stainless steel V-band clamps and a pre-applied layer of high-temperature butyl rubber sealant (resistant to 300℃), eliminating the need for on-site sealant application or specialized crimping tools. The hose’s flexible structure (minimum bend radius 135mm) allows easy routing around engine bay components, even in tight spaces between the turbocharger and intercooler. Installation follows three simple steps: remove the old hose and clean flanges, slide the new hose over the turbocharger and intercooler outlets, and tighten the V-band clamps to 15-18N·m with a standard torque wrench. The package includes 4 M8×22 galvanized bolts, a replacement gasket, and clear labeling (“TURBO SIDE” and “INTERCOOLER SIDE”) to prevent incorrect installation. A single technician can complete the entire replacement process in 20 minutes or less, minimizing truck downtime and reducing maintenance costs for fleet operators
