Hose/Line HVAC: Procedures
Connections Of Refrigerant Lines To The Components (different Versions)
NOTE:
-
In January 2003, the connections between the refrigerant lines and the various components (condenser, evaporator etc.) were converted from
radial/axial sealing to radial sealing (gradual introduction). A further few thousand vehicles were still installed with the old type of connection in
April/May 2003.
-
It is only permissible to combine components with the same type of seal and the corresponding O-rings (different versions).
-
Reliable sealing of the joints cannot be ensured if components with different forms of sealing are installed.
-
Joints with radial/axial seal (installed up to January 2003, gradually discontinued)
-
Component -A- (e.g. condenser) with connection for radial/axial seal
-
O-ring - B - for connection with radial/axial seal
-
Refrigerant line - C- with connection with radial/axial seal
-
Joints with radial seal (as of January 2003, gradual introduction)
-
Component -A- (e.g. condenser) with connection for radial seal
-
O-ring - B - for connection with radial seal
-
Refrigerant line - C - with connection with radial seal
-
Guide sleeve - D - (plastic) at connection with radial seal
