Oil for Minisplit Flare Nut Threads
I am DIY installing a Fujitsu minisplit (15LZAS) in my basement. The install manual says to use Alkylbenzene oil on the threads of the flare nuts. I can only find alkylbenzene oil available in 1 gallon or larger quantities, which is both expensive and wasteful for just needing to make 4 connections. Google tells me that POE oil should also be comptatible with R410A. Can I use POE oil safely for the threads? Does anyone have an idea of where to find Alkylbenzene oil in smaller quantities?
