AC compressor O-ring sizes

[BeefyA4]

Hello I grabbed some o rings for the lines to my AC compressor from the dealership but they had a hard time finding which ones they were, I got the lines off today and realized neither of them are correct.
Do any of you know the part numbers or or ring sizes on the lines directly on the compressor? It's a 1999 AEB 1.8t.

According to the diagram above, you will need #15 & 15A to fit your compressor. I would recommend measuring your original o-rings to find the appropriate sizes.

However, several part numbers and sizes are listed for #15 & 15A o-rings :

Number Size P/N
15 11,1X1,8 8E0 260 749 B
(15) 16,7X1,82 X 1H0 820 749 H
(15) 17,2X1,82 X 7H0 820 749
(15) 17X1,8 X 1J0 820 749 B
15A 23,8X2,4 4D0 260 749 A
15A 23,8X2,4 8E0 260 749 C
(15A) 14X1,8 X 8E0 260 749 D

Hope this helps!
