DIN and SAE Brake pipe Flares

[elebub]

Replacing front brake lines with cunifer. The old BMW steel pipes have single DIN flares. Can I replace these with single SAE flares, the thread pitch on the SAE connector is the same.

I have had no problems with single flares in kunifer,my biggest problem has been making the OE pipe flare to fit a connector usually in a 'difficult' area to get the damn tool!

My brake pipe flaring tool is ancient, so is almost certainly imperial. It makes perfect single and double flares on metric pipe (which is imperial anyway!), and if there is some small difference, that's sorted when tightened down into a fitting.
If you're referring to the hollow bolts that the pipe goes through, there's just enough difference in the metric and imperial version to nicely screw up the threads in the fittings, as I discovered once when my local motor factors sold me imperial ones, insisting, even when queried, that they were metric!

Thanks for the replies. I was concerned about the differing shape of the flare as in the picture rather than the hollow bolts. I thought it might be important to replicate the DIN flares as on the old pipe I have just removed. Although my brake flare tool can do DIN flares it's a lot easier to do good SAE ones. Thanks for the reassurance Brian I was in danger of getting a bit anal.

The taper on the SAE fitting will crush to DIN fine but if you try do it backwards DIN to SAE more likely to leak under high pressure supposidly.
