Where to find this brake fitting?

I just rebuilt my master cylinder and airpack. Apparently I've lost the fitting that screws into the rear of the master cylinder to attach the brake line (not the flare nut, but the fitting the flare nut screws into).

I have the nsn: 4730-00-591-5134. Problem is I can't find anything that matches it, only fittings that match one end or the other. Local shops just look at me like a three headed monkey.

Can anyone point me in the right direction?

Hmm...

@ldmack3, that doesn't sound promising. But, looking at the link @davidb56 posted, this might be the right thing?

Thanks @frank8003 . That's the part number and NSN I found as well. Asked local shops about it and got a blank stare. Not a bad idea to message peashooter though. I'll do that. Thanks!

@Mullaney , yes sir, have the washers. Deuce was missing both of them when I brought it home.

@BEASTMASTER , I haven't tried white owl. Just figured out I was missing the thing last night. Had hoped I'd find something local this weekend but to such luck. I'll be making some phone calls on Monday.

Sucks... Brake system is completely rebuilt- wheel cylinders, lines, airpack, master, and new remote reservoir. But can't make it go for one dang fitting 😡

Did you ever find the fitting? I'll be going to split system and will need some.
Perhaps use something as an adapter then a fitting that fits the line?
