I have a vacuum pump with a flare cross fitting (two 3/8" and what looks like 1/8" flare). This fitting is very well set in the pump and I could not unscrew it with about 50 ft lbs of force (guesstimated). I do not want to use more force and would prefer to get an adapter. Something like 3/8" flare to 1/4" NPT. The catch is that the adapter must be female flare, not male, as it usually happens. I looked in usual placed like our local hardware store and McMaster, and did not find much. Any suggestions?
