Denny,
What would say the sizes are of the two ends on the fitting (sorry if you already posted this but I cannot figure this out)?
flare angle needle valve
1. male NPT - size?
2. inverted flare (45 degree male) - size?
It looks like Eaton might have a 90 degree brass shut-off with the above ends (Dorman's looks like the one sold by JC).
