Flair Tool for Oil Lines

P.S. It"s called a double flare because just when you make a really nice one you see the flare nut on the bench and you have to cut the line, put the nut on and flare it again. ;>)

Make sure the angle of your flare matches the fittings you are attaching to.

Most automotive and industrial fittings are 45 degree, and aircraft are 37 degree, and require different tooling due to the different angle.

The double flaring is done to provide additional strength and sealing in a brake system where the pressures are rather high.

You clamp the steel line in the flaring tool clamp with slightly more protruding than you would normally have to make a single flare. Then you drop the "mandrel" or "die" into to end of the tube, and clamp it with the flaring tool. This squishes the steel tubing inward. Then you remove the "mandrel", and clamp down the flaring tool as you normally would. This doubles the flare down onto itself, producing the double flare.

So if you already have a standard flaring tool, all's you need is the double flare adapters.

And, be prepared to make some practice flares, and be prepared to be aggravated.

Here's a link to someone's site showing how the process works:
