A/C Refrigerant System Component Description
A/C System Hoses and Lines
The mixture of refrigerant oil (PAG oil) and refrigerant R-134a attacks some metals and alloys (for example, copper) and breaks down certain hose
material. Use only hoses and lines that are identified with a green mark (stripe) or the lettering "R-134a".
Hoses and lines are fastened together with threaded couplings/fittings and are retained (to bodywork or components) with specially isolated hose
clamps.
‹› During servicing, all couplings, fittings and related fasteners must be torqued to specifications => [ A/C Refrigerant System Component Overview
] See: Service and Repair/Removal and Replacement/A/C Refrigerant System Component Overview.
‹› Ensure that only special tools (as specified) are used while servicing.
