- When installing, replace the O-rings with new ones. Use O-rings suitable for HFG-134a refrigerant (R-134a).
- Apply SP-10 compressor oil to the O-rings when installing.
- Do not allow compressor oil to come into contact with vehicle parts. In case of contact, it must be removed immediately with a detergent and wiped dry.
