Is there a pipe dope you specifically recommend? I have some "Oatey Great White pipe joint compound with PTFE" at the house I was thinking i could use. Says it's rated to 3000 psi.I thought it was one you bought this way. Yes brass is not very forgiving. It will split before you can say "oh spit". Pipe dope made for gas fittings under 1/2" NPT either tape or dope above that. Nothing on flare fittings. I don't have a ready photo of a flare fitting but maybe someone can post one for me to illustrate
