Does anyone know the proper o-ring sizes for the 2002 Lancer LS connections at the A/C Compressor High and Low Ports, the Accumulator ports and the Expansion valve ports?
If no does anyone know if there is any info online that details proper o-ring sizes for A/C. Purchased a A/C Compressor kit w/o-rings and having a lot of trouble holding vacuum especially at the Accumulator.

Thanks

 

1/2"(MB946605) and 3/4"(MR117263) at the compressor, i'm pretty sure...the o rings should be on the lines though, not the compressor, did you remove them, or were they damaged?...can't find the spec for the accumulator O-rings, but the part number is MB946604, and there's two.
