2nd Gen Non-Engine/Transmission A/C low pressure switch o-ring

[JRS]

Replaced the low pressure switch on my A/C. Much to my chagrin, the new switch (from dealer) did not come with new o-ring. No part number shown for o-ring. Purchased A/C o-ring assortment at auto parts store, and of course it came with EVERY A/C o-ring one would ever need, except the one I needed. Local Carquest had individual o-rings close to the right size, but nothing exact. Ended up re-using the old one and of course, it leaks. Where can I find one the correct size?

Every low pressure switch that I ever bought came with a new Oring. Take it back to the dealer and either return it or have them give you an Oring. If they have another on the shelf, it will most likely have a new Oring in the box. Someone may have needed an extra. If they won't be decent about it, just return it and get one from the parts store.
