This comes up occasionally. Could someone put all the info into one thread and make it a sticky.
This thread is NPT fittings. Consensus seems to be 1.5-2 turns past lightly snug taking clocking into account.
Then there's flare fittings. Aluminum to aluminum, aluminum to steel, steel to aluminum, steel to steel, staninless to aluminum, stainless to steel, yada, yada. What are the torque values or is it flats? What radio station should be on? Rock, Country, Jazz, Blues? Seriously. One thread with some common sense postings or tables that are easy to understand would be greatly appreciated. Military Spec seem to enjoy confusion. Look at what they did to AN part numbers.
Heck, I would be happy to compile something to a spreadsheet if I had the data. Tabs for each material maybe.
Common folks. Lets help each other. Isn't that why we do this crazy thing?
