*** No discussion or comments, goal is one thread with A/C oring sizes compiled for easy access.

I'll edit this thread with any updates as long as I'm allowed.

 

The compressor orings are notorious for degrading faster than the others, they are usually hard/brittle and the rest in the system are still fine.  I've never seen the other orings be that way so they're not that important but list them if you do them.

 

Year, Model, Engine, A/C compressor brand:

 

1999 Impreza 2.2, ZEXEL:

Compressor:  17.8mm x 2.5mm

Compressor:  10.8mm x 2.4mm

Drivers side condensor:  10.8mm x 2.4mm

 

 

2003 3.0 H6 OBW (stock OEM compressor)

Top-rear Compressor:  17.8mm x 2.5mm
Left ('high') side Compressor:  10.8mm x 2.4mm

I usually end up taking them to the dealer and matching them.  Even the dealer books are not so good.

2003 3.0 H6 OBW (stock OEM compressor)

 

 

 

top-rear Compressor:  17.8mm x 2.5mm


left ('high') side Compressor:  10.8mm x 2.4mm

 

used the blue/green w'ever 'variety pack' o-rings from O'reilly's

 

 

used some wire to hold the throttle and CC cables 'up-and-back'. i also
pulled the electrical connection and tucked it under out of the way.
Used a rag/paper towels to clean up around the areas. I pulled the top-rear fitting
and used a toothpick to get the old o-ring off. It was much less
flexible than the replacements and deformed/flattened. The large o-ring
mentioned was a good fit. I lubed it with a little oil that was sitting
inside the compressor. Then I did the same on the left-side fitting
(high side). The o-ring was a little more difficult to remove. It was
also stiff and deformed/flattened. I think the 10.8mm x 2.4mm is the
best fit here.
