Application And Function
The pipe is part of the vehicle air conditioning refrigerant circuit. It conveys refrigerant between system components (such as condenser, evaporator, dryer/receiver or compressor, depending on the specific routing) while maintaining system pressure and preventing leaks. A compromised pipe causes loss of refrigerant, reduced cooling capacity and can allow moisture and contaminants into the system.
Installation Recommendations
For safe and reliable replacement follow standard A/C service procedures:
– Recover refrigerant using certified recovery equipment in accordance with local regulations before starting work.
– Replace all associated O-rings/seals with new ones of the correct material and lubricate with the manufacturer-recommended PAG oil.
– Use proper fittings, clamps and torque values to ensure leak-free joints.
– Evacuate the system with a vacuum pump to remove moisture and verify system tightness.
– Recharge the system to the manufacturer-specified refrigerant charge and oil quantity.
– Perform a leak check and verify cooling performance after installation.
Common Failure Causes
– Corrosion from road salts and moisture leading to pinhole leaks.
– Mechanical damage from road debris, impacts or improper previous repairs.
– Deterioration of connection seals and O-rings over time, especially after multiple service events.
– Fatigue at bends or crimp points caused by vibration and thermal cycling.
Notes For Buyers
