Detailed Product Description

This A/C suction and liquid line hose assembly combines aluminum and rubber to balance strength and flexibility, essential for handling refrigerant flow and pressure changes.

Installation Notes and Tips

Ensure the vehicle’s A/C system is fully depressurized before removing the old hose assembly. Verify that the P-nut fitting and flange connections are clean and free of debris to prevent leaks. Use the included gasket and fittings to secure a tight seal. Since this assembly does not include a bracket, confirm that the hose is properly supported during installation to avoid stress or vibration damage. Professional installation is recommended to maintain system integrity and refrigerant handling safety.
