I recently bought a tube flaring kit for three different types of tubing flares. I know how to do flares on Copper tubing , Double flares on Brake lines but i've never heard the word Bubble Flare used or where they're used. My question is where are they used? and what kind of tubing are they used on?
Thanks Kenney Kelley |

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. |

They've been around for a while on European cars at least. I'm working on an '81 Porsche 911, its brake system has all bubble flares.
