An Auxiliary Freshwater Tube serves as a conduit for the circulation of freshwater between the seawater heat exchanger and the water pump, it maintains optimal engine temperature by carrying cooled water from the heat exchanger to the pump for distribution throughout the engine. It ensures efficient and reliable cooling performance, contributing to the smooth operation and longevity of marine engines in challenging marine environments.Attributes:• Provides leak-proof connections.• Provides consistent water pressure regulation.• Resilience to temperatures and pressure fluctuations.• Smooth inner surface for optimal flow.Applications: The Auxiliary Freshwater Lines Tube is installed between the seawater heat exchanger and the water pump, forming a link in the cooling system of marine engines to ensure the efficient flow of fresh water for optimal engine temperature regulation.
