I've read many threads about single and double brake pipe flares and understand the difference, I notice that the single flares (button mushroom shape) on the pipes that I am removing are flat shouldered and look like DIN. However, my tool is SAE and I cannot find a DIN tool that makes double flares. Am I o.k to use the SAE tool for both types of flare? The single flare that it makes is bubble shaped not a button like the DIN and the original. Alternatively should I make DIN flares with one tool and then use my SAE tool to add the second operation for the female flare? Anyone had similar thoughts? Thanks............
 
On my Defender 90 1993 the pipe size is imperial like all brake most brake pipes but the fitting were metric and the flares I did were DIN as they best resembles what was there already.
Had no issues since that so it must be ok.

Andy, I've got a sykes pickavant pipe flarer that does both din and SAE. Subject to a suitably large but refundable deposit, you can borrow it.[/QUOTE

Thanks! Could you post a picture of it please to compare? I'm concluding that the single flares are DIN and the double flares are SAE. I have read that SAE single flare is comparible with DIN though!! How complex or I am in too deep??

I have this type of flaring tool, and have used it to completely re-pipe two Freelanders, and do odd jobs on other cars, using 3/16 copper pipe.

The instructions didn’t mention SAE or DIN, but rather OP1 and OP2 flares. Either way, it works very well.

Just remember that copper pipe shouldn’t be tightened like steel - Snug, then half a turn, check for leaks, nip up if necessary. If you overtighten, the joint will pop apart.

Edit: Just looked it up, and OP1 and OP2 are SAE.
 
Thanks, I think SAE flares will work fine (as you have proved!) but the freelander 'bubble' flare (not the countersunk one) does look like a DIN in that it is flat to the connector nut. Looks like SAE and DIN domes are same shape on the side that connects to the fitting though. Will carry on as I am with SAE tool and suitable metric fittings.
 
After much reading and learning I conclude that the Freelander 1 V6 at least has 2 types of flare and 3 types pipe nut required. The protruding flare is DIN and the countersunk double flare is SAE. Can we use the same pipe nut for both? No we can't. The SAE requires a 90 degree countersunk nut to support the flare. Also the ABS uses 10mm and 12mm pipe nuts. I can produce a DIN flare by turning my flare tool pipe holder upside down to give a flat side and a mushroom side. SAE flare simply put it back and do the 2 operations with the second being the 90 degree die. Will post pictures of each type to explain the above. Glad I got this straight. Does it make sense to anyone??!!!
 
I just use SAE single or double on most vehicles, including the Freelander and the D3. I've not had any trouble yet, but I always check the flare has seated correctly, once the union is nipped up. Maybe it's time I invest in a more advanced flaring machine.
 
Do you use countersunk nuts for he double flares? Metric thread and sae double flare nuts seem rare so am putting 90 deg countersink on standard nut.
 
:rolleyes: I’m afraid I just went into my local auto parts shop and asked for ‘brake pipe unions’. I was given a little bag of them and went away happy...

If you’re using copper pipe, don’t worry too much - the flares conform well as soon as you tighten.
