A Coolant Lines Hose is constructed from durable materials. The material offers excellent resistance to refrigerant chemicals, temperature extremes, and mechanical stresses. The selected material ensures flexibility and compatibility with the specific coolant fluid in the cooling system.Attributes:• Withstands minimum vacuum pressure of 10 kPa at 125 degrees Celsius• Inner diameter increases from 49.87mm to 55.3mmApplications:A Coolant Lines Hose is used to conduct coolant between the radiator hydraulic oil cooler and the engine's cylinder head. It allows coolant to circulate, transferring heat away from the engine and assisting in maintaining optimal operating temperatures.
