In process of replacing the AC evaporator valve and got the whole o-ring kit (should be enough for the whole AC system.
the problem id that as a part of the kit there are O-rings with ID of 6.8, 7.6, 11.1, 14 and 17.17, but it is missing a very small O-ring that seems to be (measured my old one) about 3.2mm ID.
This is the one on picture below that fits in the fitting circled with red.
Would someone maybe know the Santech part number or at least correct size/thickness; my old one is pretty distorted so worried not to get the right size if I just try measuring mine.
What is strange is that when looking for O-ring listings at any BMW parts vendors here (Pelican Parts, FCP,...) none lists this size O-ring while they list all of the bigger ones.
As well, I bought new evaporator valve but this O-ring was unfortunately not included.
