Radiator Outlet Hose (also known as Downpipe or Lower Radiator Hose) is a critical circulation component of the engine cooling system, responsible for conveying the low-temperature coolant (typically 60-80°C) cooled at the bottom of the radiator back to the inlet of the engine water pump. It forms a complete coolant circulation loop together with the upper hose.

Core Advantages

• Safety Redundancy Design: The bursting pressure is four times the rated pressure, eliminating the risk of rupture during operation.
• Long-term Resistance to Aging: After optimization of the EPDM formula, the actual service life can reach 80,000 to 100,000 kilometers.
• Flow Resistance Optimization: With a surface roughness (Ra) ≤ 1.6μm on the inner surface, pump power consumption is reduced by 2-3%.
• Environmental Compliance: Complies with RoHS 2.0 and REACH regulations, with a material recyclability rate ≥ 95%.
