The radiator water pipe is the core passage of the cooling system, responsible for transporting coolant, directing engine heat to the radiator for heat dissipation and reflux, and can also be diverted to components such as heaters. High quality water pipes often use TP2 copper pipes with a wall thickness of ≥ 0.8mm. They are tightly adhered to the fins through high-pressure expansion technology, with a pressure resistance of ≥ 1.6MPa and corrosion resistance
