How do my Bubble Flares look?

[mrc]

I am in the process of replacing all the brake lines on my 72 Bug. It sat for over 20 years and all the lines were clogged.

I will be using Cunifer 3/16"/4.75mm brake line tubing and nuts from Federal Hill Trading Company (FEDHILL).

The following pictures are of three samples of bubble flares I did using the Cal-Van #155 tool to practice using the tool. The pictures were taken from different angles and the samples correspond from left to right on all the pictures.

Do they look correct/OK?

Is there something obvious I should do to be sure I have proper ("perfect"?) flares?

Any and all feedback will be greatly appreciated.

Saludos y gracias.

They all look good to me. 'Perfect flare'? Don't worry about it. As long as it's not massively uneven it will form it final shape when the joint is assembled.

See if you can get them all to look like the one on the left. Like Dodgy mentioned, they probably all will seal. I've had the best luck with the copper alloy tubing having a "head" to the flare that extends outward over the edge of the threaded fitting, like your one on the left. The ones in the center/right, where the flare isn't quite as wide as the threaded fitting, have more of a chance of distorting with the softer material when tightened not making the best seal.

Dodgy, gkeeton thanks for your response and insight on the bubble flares.

Just another issue I just recalled.

I have read on a couple of occasions that a bubble flare joint once assembled the first time, would be "destroyed" and not function properly if it is disassembled and re-assembled.

To what extent is this statement true?

Saludos y gracias.

I dont think copper is a good choice.
