3/8-24 to 14mm?

I'm trying to install a Wilwood proportioning valve and can't find an adapter anywhere. Anyone have any ideas where I can source this adapter fitting? It would appear that the Edelmann 262015 everyone has used in the past is currently unobtanium. So far, I've only been able to find 12mm adapters.

Re: 3/8-24 to 14mm?

Are you trying to adapt to the 14mm nut on the brake line or the female port in the prop.valve?

It sounds like the nut. I used a 14mm 1.5 coupling, and another 14mm nut that I drilled and tapped to 1/8-27 npt then screwed in an adapter many moons ago

Rock Auto ended up re-stocking one single fitting. Pretty sure I ended up buying the only one available in the country. lol

cut the brake line, make a new one, add the fittings of your choice for ends.
