turbogrill Posted February 13, 2018 Report Share Posted February 13, 2018 Hi, I am having troubles finding M10x1.0 metric inverted flares to NPT 1/8 adapters. This is needed if you want to run Wilwood on your Japanese car. So it should be pretty common? The only two sources I have found is: - https://www.flyinmiata.com/npt-to-metric-flare-adapter.html - https://zcardepot.com/metric-10mm-to-1-8-pipe-adaptor-brake-line-fitting.html There are plenty of SAE M10x1.0 to NPT 1/8 adapeters but SAE and Metric is not the same thing. Is there something obvious I am missing? Link to comment Share on other sites More sharing options...
Bremsen Posted February 13, 2018 Report Share Posted February 13, 2018 -3 adapters on both ends and a generic -3 line? Also SAE M10x1.0 is not the same as Metric M10x1.0? Is there a flare difference or something? Threads are threads. The other option is a NPT to -3AN adapter on the caliper and custom lines. Link to comment Share on other sites More sharing options...
Ogren-Engineering Posted February 13, 2018 Report Share Posted February 13, 2018 Auto zone has a bunch hanging othe back wall. Link to comment Share on other sites More sharing options...
karman1970 Posted February 13, 2018 Report Share Posted February 13, 2018 Ditto Autozone. Bough a bunch for our Honda last year. I cleaned them out and needed more. They ordered whatever I needed and had 'em in a couple days. I'm sure any of the parts stores are the same, Autozone was just the only one that had any in stock that day.

Yes the flare is different, different angle. It *works* if you over tighten, it's close enough so that the force can deform it to work. Link to comment Share on other sites More sharing options...

Your early Z should have SAE double flare on the hard lines, not DIN.....at least according to this site: http://www.fedhillusa.com/?page=flare Link to comment Share on other sites More sharing options...
turbogrill Posted February 13, 2018 Author Report Share Posted February 13, 2018 From what I understand there are at 2 different inverted flares with different flare angle: - SAE double inverted flare (45 deg) - Japan Metric double inverted flare (37 deg) That is what this site says, http://winhpde.com/tech/brake-line-flares-metric-sae-inverted-bubble/, scroll down to "Metric Vs SAE Flares" The SAE vs DIN seems to be bubble vs inverted flare. (On anther note, seems like most of the big brake kits uses a -3 and adapter like you suggested. But I want to keep my hoses) Link to comment Share on other sites More sharing options...
Bremsen Posted February 14, 2018 Report Share Posted February 14, 2018 I'd be absolutely sure that your car uses the JIS, ours has 45° fittings in places I would have thought would be JIS (I'm having to convert to AN) and your car is slightly older. Also, from what I know, JIS and AN are the same 37° angle and can be used together. Link to comment Share on other sites More sharing options...

Bremsen Posted February 14, 2018 Report Share Posted February 14, 2018 OK, I'm mixing up JIC and JIS now. Argh, this stuff is so confusing. I'm now seeing that JIS is 30°. Never mind me, nothing to see here Link to comment Share on other sites More sharing options...
mhr650 Posted February 14, 2018 Report Share Posted February 14, 2018 Perfect example of why when I install my Wilwood calipers and pedal box I am going to replace everything with -3 and NPT, much easier to get replacement bits if I need them.

Ron_e Posted February 14, 2018 Report Share Posted February 14, 2018 The Fox Mustang uses four or five different threads both standard and metric with different types of flares in the brake lines on a single car. I also converted everything to 3/16 North American standard threads on the hard lines and -3 on the flex lines... life is so much easier this way.
