A Water Lines 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:• Facilitates the conduction of heat away from engine components, preventing overheating and potential damage• Provide a smooth, uninterrupted flow of refrigerant fluid, minimizing pressure dropApplications:A Water Lines Hose enables the smooth flow of coolant water from the one end of the hose connecting to the water pump core, while the other end connects to the engine cylinder head.
