Шланг расширительного бака, внутренний диаметр 50,8 мм Caterpillar 3665911

An Expansion Tank Hose provides a fluid passage between the cooling circuit and the expansion tank to manage changes in coolant volume caused by temperature variation. As coolant temperature rises, liquid expands, and excess volume moves through the hose into the expansion tank. When the temperature decreases, the coolant contracts and fluid returns through the hose to the primary cooling circuit. This bidirectional flow maintains balanced coolant levels and stabilizes internal pressure conditions.Attributes:• Maintains controlled coolant expansion transfer.• Smooth inner bore supports steady fluid flow.• Secure clamp fit ensures leak resistant sealing.• Flexible structure absorbs engine vibration.• Capable of withstanding 145 kilopascal water pressure.Applications: An Expansion Tank Hose connects the cooling circuit and expansion tank to allow transfer of expanding and contracting coolant for pressure stabilization and temperature regulation during system operation.
