The radiator water pipe is a critical channel in the engine cooling system, with the core function of transporting coolant, taking away engine heat to the radiator for cooling, and diverting coolant to components such as the heating core. High quality water pipes are made of anti-aging rubber or TP2 copper, with a uniform wall thickness of ≥ 0.8mm, tightly sealed interfaces, pressure resistance of ≥ 1.6MPa, resistance to high and low temperature impacts, and corrosion resistance.
