A Water Heater Tube Assembly is used in the cooling unit of an internal combustion engine. The tube facilitates the regulation of engine temperature by controlling the flow of heated coolant through the engine block. The assembly includes an O Ring Seal Sleeve, and Swivel nut on both ends to ensure a secure and leak-free connection.Attributes:• Allows for precise regulation of engine temperature• Ensures efficient coolant flowApplications:A Water Heater Tube Assembly serves as a conduit for the flow of coolant through the tube, it absorbs heat from engine components, helping to regulate their temperature.
