Refrigerant Circuit Pipes And Hoses

WARNING: This page does not describe the selected car, but rather 9 other vehicles, including the 2015 Audi S7, 2015 Audi RS 7, 2015 Audi A7 Quattro, 2014 Audi S7, and 2014 Audi RS 7. However, it is still accessible from the selected car via links, so may be relevant.

The mixture of refrigerant oil and refrigerant R134a corrodes certain metals (such as copper) and alloys and dissolves some hose materials. Therefore use original replacement parts only.

Pipes and hoses are joined by threaded connections or special plug connectors.

NOTE:

Observe specified torque for threaded connections, use appropriate release tools for plug connectors.
