Replacing O-Ring Seals

NOTICE: Use only R-12 Refrigerant oil (mineral) to lubricate O-rings. Use of R-134a (PAG) oil will cause premature corrosion of fitting joints.

1. Install new Saturn approved service replacement air conditioning O-rings whenever a joint or fitting is disassembled, except when provided on new components. Even though an O-ring may look the same, it is extremely important that only recommended service replacement air conditioning O-rings 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 (eg., 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.
