Thanks to everyone who answered my question. I knew the Bubble Flare was different from the others because it required a different flaring cone all together and i had never seen one so that's the reason why I asked. Once again thanks for the response.

A bit late but a bubble flare is a European standard and not common on US cars. Not sure its road legal in this country. Inverted double flare is stronger. Always match flares and fittings. Here's a chart.

A word of caution.
If you are using a bubble flare, make sure the mating components are designed for a bubble flare. The flare has a different shape and will not fit into double flare connections. You cannot connect a bubble flare to a double flare seat.

They have a built in crush surface which means that the flare can not be reused. You also can not connect a bubble flare to a double flare seat.
