A Water Line Elbow helps to regulate the flow and temperature of coolant which is connected to the expansion tank and heat exchanger. It is made from durable material such as gray iron allowing coolant to flow between them and facilitate this pressure release which allows the coolant to flow back into the heat exchanger when the pressure subsides. Attributes:• Withstands water pressure of 240 kPa which is resistant to failure or leakage• Helps prevent damage to the cooling unit components due to excessive pressure buildupApplications:A Water Line Elbow enables the return of coolant from the expansion tank back into the heat exchanger and ensures a continuous flow of coolant through the heat exchanger, promoting efficient heat transfer and cooling of the engine.
