Brake line removal/repair/replacement (something?) help

[gatesj at mailblocks.com (John Gates)]

Yes, 3/16" is the same line as whatever the metric is, 4.5mm or 
whatever.  I have run pieces of the NAPA 25' 3/16" roll on my Scirocco 
with no problems.

That site is a little confusing, the british bubble flare is NOT what 
we're talking about for VW, as far as I know the correct name is metric 
bubble flare OR ISO bubble flare..  The british one is a breed all by 
itself.  I don't know what the metric invert flare is but I am guessing 
it looks like an american double flare, just sized differently.

I THINK 3044 off that page is the union you want, it is the only one 
that makes sense to me.

I also think that 3414 is the nut you want, I remember the violet color 
coding.  3028 may be right too for a shorter nut but I am not sure.  
The thread is 10mm x 1.0mm, same thread on the olive and violet nuts, I 
believe the only difference is nut length.  There are some fittings 
where the nut needs to be longer to screw into the appliance all the 
way, others where a shorter nut is better.

Note the thread on the union is the same as the thread on the nuts I 
picked out.

Hope this helps...

Thanks for the link, there is stuff there I can't get locally!

Awesome, thanks John!
So, can anyone confirm which one of these UNIONS would work with the 
stock male
connectors?  Or do I have to buy new male adapters as well?  It says 
3/16" pipe
size for most of these, would that be correct?
