Product Overview
The 3076418 upper radiator hose is built for the Hitachi EX400-5 excavator, carrying heated coolant from the engine toward the radiator for cooling. Constructed with high-grade, heat-resistant rubber, this hose remains stable under continuous thermal load and high flow rates typical of large-frame excavators.
Its molded curvature ensures proper routing through the upper section of the cooling system, preventing contact with moving components and maintaining efficient coolant transfer.
