Custom Brake Lines - Plumb Crazy

The valve was closed on the hydraulic pump.

Next, the male cone adapter was pumped completely forward into the inverted die.

Then the valve was released by turning to the "open" position, the male cone adapter was removed from the yoke, and the 3/16-inch inverted male adapter was put in its place.

With the valve now turned to the "close" position, the male inverted adapter was pumped forward until it...

...fully seated into the face of the female inverted die.

Once fully seated, this action completed the double-flaring process, the valve was opened for the last time, and the 3/16-inch tubing and the dies were removed.

Here's a close-up of the completed double flare. Notice that it is perfectly formed and is equal in appearance to a factory double-flared end. In addition to 45-degree double flares, the deluxe kit includes dies for swaging GM push-connect fuel lines and dies for metric bubble-flaring.
