How is FlareSeal® better than liquid thread lock products?
The sealing surface is the most important part of the flare connection. FlareSeal® has multiple rings on the copper crush sealing surface providing extra points of connections. The FlareSeal® helps compensate for any mis-alignment between the male fitting and the flare. Any imperfections in the flare connection are filled in by the proprietary Loctite® coating on the copper seal.
