can you mate a double flared to a bubble flared line? I've got these fittings (male double flare) and (female fitting... looks like its for a double flare) , was hopping I didn't need a male to male union.

Thanks muc

@marshkid1 I do a comination flare with thise, usually on the male side. You'll need a bubble flare kit in addition to a double flare to do this. First, make a bubble flare as normal. Then, with the line still in the bubble flare die, use the 45 degree ram from the double flare kit to complete it. I've done several this way, none have leaked.

I may make video of it, as some as I can scavenge an original one to show what I'm copying.

I'm having trouble with my brake lines. I make my flare but then my fitting won't slide down the line to the flare. It gets hung up around where the bottom of my die sat. How can I fix this problem?

@jhonea005 Sometimes the die will leave raised areas in the metal where it was clamped, similar to knurling a valve guide. You may need to do some ligth sanding around the area where the fitting goes to get it to slide down.

He is wrong when he uses vice grips and crow bars to tighten the bar. You should tighten the screw closest to the size of the tube first, and then tighten the farthest screw, by hand.

@dgn1978 You are correct. However, the tool I'm using in this demonstration is almost 20 years old, and has worn out over the years. About the only way i can get it tight anymore is to do it as shown in the vid. It's also the reason i no longer use it. I now use a Blue-Point that I got from the Snap-On dealer. Much more expensive, but does a far better job.

Technicaly, you're not supposed to use tools to tighten the stock. However, I've found that it can be difficult to get good clamping force on the line just hand tightening the wingnuts. This is especially true if you're flaring a line that is on the vehicle that may either be dirty or in an awkward position. The reccomendations of the manufacturer are a good starting point, but real world conditions will dictate what really need to be done to make the tool work.
