A/C Coupler O-ring: Service Precautions
O-RINGS AND SEAL WASHERS
NOTE: Use only R-12 Refrigerant oil (mineral) to lubricate O-rings. Use of R-134a (PAG) oil will cause premature corrosion of fitting joints.
Do not lubricate seal washers.
1. Install new Saturn approved service replacement air conditioning O-rings and seal washers whenever a joint or fitting is disassembled, except
when provided on new components. Even though an O-ring and seal washer may look the same, it is extremely important that only recommended
service replacement air conditioning O-rings and seal washers be used or leakage of refrigerant will occur.
2. When replacing O-rings on an air conditioning component or joint connection, the fitting design should be carefully identified to ensure
installation of the correct air conditioning service replacement O-ring. Use a non-metal tool (e.g., plastic pick) to remove O-ring to avoid
damaging the mating surface on the fitting.
3. O-ring should be coated with new R-12 mineral compressor oil prior to installation, but must not be soaked.
4. Prior to installation, verify that both O-rings and fittings have not been nicked or deformed. Deformed or nicked parts must be replaced. Failure to
use the proper service replacement parts and procedures may result in excessive refrigerant leakage.
