What is the reommended lubrication for the o-rings?
Green o-rings are usually HNBR compound.
Use can use ester, PAG, AC mineral or spit on them, so long as they don't bind and shear when you snug up the fitting.

George, if you’re not in a big rush I’ll mail my bottle to you for the cost of the freight. I just bought it to overhaul my ac a few months ago and only used a few droplets. Probably won’t get a chance to stop by the post office until next week. Just drop me a pm with your email if you want to avoid spitting on the orings

Nick, many thanks. I will give the swiss reseller another day to answer, and if he does not, I will take you up on the offer. Spit withheld for now
