Does anyone know the correct size for the 2 o-rings used on the lines to the a/c condenser? Or the Jag part number? Jaguar parts catalog does not show a breakdown with o-rings, just the line sets. Both rings are the same size.

Completely frustrated that I did not have a correct size replacement o-ring while in the middle of my condenser replacement, even though I have a box set of ac o-rings and I bought a bag of o-rings supposedly for this vehicle (none of those looked even remotely close to fitting anyplace on the Jag). Had to put back the originals. Expecting those to leak.

Thanks,

To answer my own question, the original Jag part number is C2N1185 for the condenser o-rings on the x350 XJ. However, they are approx $7 each and have to be ordered. I found part number XR83775 is the condenser o-ring for the S-Type, XF, XK, and the X Type for models from the early 2000s through 2010s. At only $1-change I've ordered 2 of these. From looking at the condensers themselves, it appears they will be the same. I will post back to confirm.

 

To follow up, C2N1185 is the correct o-ring for the condenser lines. The later part (XR83775) is too small. The dimensions of the correct o-rings are 10 mm ID, 2 mm CS. They are black colored o-rings just like the factory ones on the car, which surprised me. Usually HNBR are green, but that's just dye added for identification purposes. I would not use a plain rubber o-ring on the a/c system.

 

Try a local bearing shop if you have one..
Otherwise since you now have the sizes.
The internet should provide a source.
Ebay with Pay Pal seems to work for me,finding stuff.

 

Now that I have measurements they're a dime a dozen. Problem was I didn't want to take the system apart and leave it open to atmosphere while I dissected the original o-rings. Hopefully this is of some help to someone else in the future.

 

Yes me!

Thank you
