Dongfeng Renault Engine parts Air compressor inlet hose assembly D5010477313

Crafted from a premium EPDM (Ethylene Propylene Diene Monomer) rubber compound reinforced with a high-tensile polyester cord layer, this inlet hose assembly delivers exceptional durability and resistance to harsh engine environments. The EPDM rubber withstands extreme temperatures ranging from -40°C to 120°C, making it suitable for engines operating in cold winter climates or hot summer conditions without hardening, cracking, or softening. The polyester cord reinforcement enhances the hose’s tensile strength and pressure resistance, allowing it to handle the air compressor’s inlet pressure (up to 15 psi) without bulging or splitting. Additionally, the rubber compound is resistant to oil, grease, and engine coolant—common contaminants in engine compartments—ensuring the hose maintains its structural integrity and flexibility for over 100,000 kilometers of use

Engineered with a smooth inner lumen and consistent diameter (free from kinks or narrow sections), the D5010477313 inlet hose assembly maximizes airflow to the air compressor, directly improving the compressor’s efficiency and performance. The smooth inner surface minimizes air turbulence and pressure loss, ensuring the compressor receives a steady, high-volume supply of filtered air—critical for maintaining optimal air pressure in the vehicle’s braking system, suspension, or other pneumatic components. Computational Fluid Dynamics (CFD) simulations were used during design to validate airflow efficiency, confirming that the hose delivers up to 98% of the required air volume to the compressor. This optimized airflow not only reduces the compressor’s workload (lowering fuel consumption indirectly) but also prevents overheating and premature wear of the compressor’s internal parts

Equipped with precision-molded rubber end fittings and stainless steel hose clamps, the inlet hose assembly ensures a tight, leak-proof seal at both the air compressor inlet port and the air filter housing (or air intake manifold). The end fittings feature a ribbed design that grips the mating ports tightly, while the stainless steel clamps (included with the assembly) provide uniform pressure to lock the hose in place—preventing air leaks that could reduce compressor output or introduce unfiltered air into the system. Additionally, the hose is designed with a protective outer sleeve (on select models) that shields it from damage by hot engine parts, moving components, or road debris. This dual protection (sealing + physical shielding) ensures the hose remains functional even in high-vibration engine compartments, avoiding costly repairs caused by air leaks or hose damage

Designed for hassle-free installation, the D5010477313 inlet hose assembly comes with pre-marked alignment indicators that help technicians quickly position the hose correctly—matching the original mounting points and routing path. The included stainless steel clamps are pre-sized to fit the hose’s end fittings and the engine’s mating ports, eliminating the need for measuring or selecting additional hardware. No special tools are required; a standard screwdriver or socket wrench is sufficient to tighten the clamps. Once installed, the hose requires minimal maintenance: regular visual inspections (to check for cracks, bulges, or loose clamps) are all that is needed, as the durable EPDM rubber and corrosion-resistant clamps resist wear and degradation. This easy installation and low maintenance design reduces vehicle downtime during repairs and lowers long-term maintenance costs for fleet managers or vehicle owners
