Blue thread sealer can be used but you run the risk of it clogging the line if it spreads out from the threads to the tip of the fitting. It's safer to just use thread sealant tape like # 37207-30025 to avoid any clog issues. You would not want to use thread sealant on flared fittings since they'll have a gasket to prevent leaks.
