Durability that Outlasts the Road
Shanghai Yida employs advanced robotic welding and leak-detection systems. Each pipe assembly is coated with an anti-corrosion layer that resists salt, moisture, and road debris.
The WG1642821072_2 model has been tested under continuous vibration and thermal cycling, ensuring that it maintains structural integrity even on the roughest terrains.
Installation & Maintenance Tips
Fitting the expansion valve connecting pipe assembly is straightforward. Clean the mating surfaces, apply a thin layer of refrigerant oil to the O-rings, and torque the fittings to 25–30 N·m.
For best results, replace the drier receiver and expand the system vacuum before recharging. Regular inspection of the pipe’s surface for abrasion is recommended every 30,000 km.
Performance Advantages
15% faster cabin cool-down
Reduced compressor strain
Fuel efficiency improvement
Zero leakage guaranteed
By optimizing the expansion valve’s response, the connecting pipe assembly reduces pressure drops and ensures that the evaporator receives a steady refrigerant supply.
Drivers experience consistent air conditioning output, while the system operates with lower noise and vibration levels.
