Dongfeng xinjiang truck parts Engine inlet exhaust hose 1119124-T5XF01Y

Built to maximize airflow efficiency in both intake and exhaust systems, this hose features a smooth inner cavity (Ra ≤ 0.8μm) and optimized structural design. The non-stick inner surface minimizes airflow resistance, reducing pressure loss by 22% compared to standard rubber hoses with rough interiors. Its 76mm inner diameter ensures a maximum intake airflow rate of 380m³/h, matching the air demand of 460-520hp engines, while the flexible elbow design (bend radius ≥ 150mm) avoids airflow turbulence at the turbocharger connection. For exhaust applications, the hose maintains consistent gas flow to the aftertreatment system, reducing backpressure by 15% and enhancing turbocharger response time by 10%. By ensuring efficient air intake and exhaust, the hose improves fuel combustion efficiency by 8%, boosting engine power output and reducing fuel consumption under heavy loads

Engineered to endure the harsh conditions of engine inlet and exhaust systems, the hose integrates a multi-layer composite structure for exceptional temperature and pressure resistance. The inner layer is made of high-temperature silicone rubber (resistant to -40℃ to 260℃), capable of withstanding continuous exhaust gas temperatures and sudden cold starts in frigid climates. The middle layer is a high-strength aramid fiber reinforcement, providing a working pressure rating of 1.5bar (peak pressure: 3.0bar) to resist expansion or burst during turbocharger surges. The outer layer is a heat-resistant EPDM rubber that shields against radiant heat from the engine block (up to 300℃). In durability tests, the hose maintains integrity through 50,000 thermal cycles (-30℃ to 250℃) and 100,000 pressure cycles, far exceeding the service life of standard rubber hoses

Designed to resist the diverse threats of commercial truck operation—including chemical corrosion, UV radiation, and mechanical wear—the hose delivers long-lasting reliability. The outer EPDM layer is resistant to diesel fuel, engine oil, road salt, and cleaning chemicals, preventing swelling or degradation from accidental spills. It passes 2000-hour QUV UV testing with no cracking or brittleness, ensuring durability in sunny desert or high-altitude environments. The integrated stainless steel clamps (304-grade) resist rust and corrosion, maintaining a secure seal even after 1000-hour salt spray testing (ASTM B117). Additionally, the hose’s flexible structure absorbs engine vibrations (5-2000Hz, compliant with ISO 16750-3), reducing wear on connection points and extending the service life of adjacent components (e.g., turbocharger, intake manifold). This comprehensive durability ensures the hose functions reliably for over 6 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, eliminating the need for specialized crimping tools. The hose’s flexible structure (minimum bend radius 120mm) allows easy routing around engine bay components, even in tight spaces. Installation steps are straightforward: slide the hose over the inlet/exhaust flanges, align the mounting holes, and tighten the clamps with a standard socket wrench (recommended torque: 12-15N·m). The package includes 4 M6×16 galvanized bolts and a high-temperature gasket (resistant to 300℃) for a leak-proof seal. Clear labeling (“INLET SIDE” and “EXHAUST SIDE”) prevents incorrect installation, and a single technician can complete the replacement in 20 minutes or less—minimizing truck downtime and reducing maintenance costs for fleet operators
