    R134a is the best long term alternative refrigerant to replace R12.
    under no circumstances we should reuse R12 as it's ozone deplating refrigerant .any amount of R12 should be recovered for final disposal. I guess your system was manufactured before 1990.

    Best replacement

    What is the best replacement chain for the 93 1000F? If I remember correctly, OEM is 530 O-ring. However, Im thinking of replacing it with X-ring from RK or DID. Any comments?
