In the delivery of engine cooling water, the role of the hose is crucial. It is responsible for connecting various components of the cooling system to ensure smooth circulation of cooling water. At the same time, the hose can absorb engine vibration, play a role in shock absorption and buffering, and protect the stable operation of the cooling system. Due to the complex layout of the engine room, the hose needs to adapt to different installation environments to ensure that the cooling water reaches the required parts. In addition, the hose must have good sealing performance to prevent cooling water leakage.
Material of engine cooling water delivery hose
EPDM hose
This is a common rubber material. It is widely used in engine cooling water hoses due to its excellent heat resistance, cold resistance, ozone resistance, UV resistance, water resistance and chemical stability. It also has excellent elasticity and aging resistance. Therefore, it can ensure that the hose maintains good flexibility and sealing during long-term use.
Polyolefin hose
This type of material usually has good heat resistance, chemical corrosion resistance and mechanical properties. Polyolefin hoses are stable under high pressure and high temperature environments. Therefore, they are suitable for cooling systems that need to withstand large pressures and temperature changes.
PU hose
Hoses made of polyurethane materials have good wear resistance, elasticity and tear resistance. They are usually used in occasions that need to withstand large mechanical stress. Such as areas with complex layouts in the engine compartment.
