Anybody know if the AC o-ring assortment kits at Napa have the right size O-rings for these cars?

I need to replace the condenser in my 95 Legacy. The o-ring on the compressor discharge hose on the left side was leaking because it was corroded underneath, and the bottom corner of the condenser is corrode through and leaking. So if I have to replace 2 I might as well do them all while I have the system open.

So rather than pulling all of the o-rings out and trying to match them I'm wondering if I got one of those assortment kits of that would have all the sizes I need. It's like $5 and has about a dozen o-rings.

I usually get them out of the assorted kits I have left overs of in my tool box. Anything from honda to che vy kits they seem to be pretty common sizes so I would say you will probably be fine. I just dig out what ever matches the best and err to the bigger side.

I have found the "Asian import" o-ring kit has everything I've needed.  I'm not sure what Napa carries specifically.

Yeah they have two kits I was thinking of trying. One is a generic kit which I guess covers most cars, the other is some generic metric kit that has about 25 o-rings, but its $15 vs $5 for the smaller kit.

Ill probably replace the accumulator too since its $14 new, and those usually come with o-rings. So I really only need the 2 on the compressor and the 2 on the condenser.

yes and no.

 

i've used the kits to seal complete systems but it's not ideal and might want to tweak it.  and i'm sure kits vary, i've bought a number of kits over the years that populate my A/C tool kit/boxes.

 

the compressor orings are always an easy fit.  the condensor is usually fine.  after that they get smaller and trickier.

 

note - the "actual size" drawings depicted on the back of some packages aren't accurate.

 

the tiny orings through the system are much harder to match.  the ID will be right but not the thickness or the OD will be right but not he thickness or the thickness is right but not ID.  end up stretching one really thin to fit or having a loose one that you hope seals.

 

the old orings have always been in good shape that i've pulled so i don't know if there was a net gain in replacing them with incorrect sizes.

 

if i wanted  to do one right for the long haul i'd probably plan on matching the compressor and mic'ing the rest or just mic them all. they're usually in great shape and should be easy to measure unlike the compressor orings which are often compromised.
