How to make a double inverted brake line flare Part 3

A double inverted brake line flare, also known as a double flare, is a method of flaring the end of a tube to create a secure and leak-proof connection with a fitting. The process involves two distinct steps: creating an initial flare and then folding the flare back onto itself to form a double layer. This double layer increases the strength and durability of the connection, making it particularly suitable for high-pressure applications such as brake and hydraulic systems.

Making a double inverted flare using a S.U.R.&R. PFT409 Piston Grip Flaring Tool Kit is a three-step process. This is the easiest way to make any kind of brake line flare.
