I was surprised at how easily my old AC threaded fittings came apart. When installing new parts is there a lubricant/sealer used on the aluminum threads? 134A if that makes any difference.

Threaded alone parts I like silicone grease and some have used the aluminum colored anti-seize, brush in cap stuff. Nylog, and or mineral oil for rubber most popular. Avoid PAG refrigerant oils for a lube for these things,

Thanks Tom. Now that I think about it, would be difficult to use one thing on O ring and not contaminate it with something else used on threads??

I have mineral oil dripping out of my old evaporator, could I use that for lubing O rings and threads??

When are you coming to Ft Myers to visit? Jim

Lube exactly what you intend with exactly what you want to use. IDK, used real mineral oil really should be fine. Heard of some using baby oil if marked as mineral oil for "O" rings. I still like silicone grease for any of those the alloy threaded things too. Those in particular you said came apart well? Either had been treated before or might have fooled you and look hard if threads just gave out transferring metal such that they aren't really threaded well enough to work again at all?
Keep assorted products OUT of where if can get into refrigerant. The rest is assorted plumbing and sealing methods.


Again - note PAG oils that seem like and are a lube are also able to absorb moisture and change characteristics you don't want so plain don't use that as lube for other than called for inside a system,
