A Radiator Upper Hose is constructed from materials resistant to the fluid being conducted. The inner diameter of a hose refers to the measurement of the hollow hose's internal opening. It determines the flow rate and volume capacity of the hose. The outer diameter of a hose refers to the measurement of the hose's external circumference.Attributes:• Withstands vacuum pressure of 7 kPa at 120 degrees Celsius • Manufactured to precise specifications and are built for durability, and reliabilityApplications:A Radiator Upper Hose is used to facilitate the flow of hot coolant from the engine block to the radiator inlet. The hose allows the coolant to circulate, absorbing heat from the coolant, and again conducting the cooled coolant to the engine.
