Refrigerant Circuit Pipes And Hoses

In the right state refrigerant R1234yf is chemically stable and does not damage iron, aluminum and corresponding developed and suitable plastic. Mixing refrigerant oil and refrigerant R1234yf can damage specific metals (for example alloys with copper) and can damage and dissolve specific hose materials and plastics. For this reason use only original parts. Refer to the Parts Information.
Make exclusive use of components which are resistant to refrigerant R1234yf and the related refrigerant oils. Do not use any components (such as seals and hoses that are made of plastic) which were not clearly assigned. Refer to the Parts Information.
The pipes and the hoses are held together with bolts or by special connections. Refer to the appropriate information (REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT ) (vehicle-specific repair information).
Replace the sealing components (for example seals) between the components. Refer to the Parts Information.
Note the tightening specification on threaded connections, for connectors use the corresponding release tools. Refer to REFRIGERANT LINES, DISCONNECTING FROM QUICK-RELEASE COUPLINGS AND CONNECTING or the appropriate information (REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT / REFRIGERANT CIRCUIT ) (vehicle-specific repair informations.
