Help, I think Im loosing my mind trying to get my vacuum pump set up for my degassing chamber. I have this pump (LINK): and I need to adapt the 3/8" SAE flared fitting to NPT. Once I get an NPT fitting I'm good to go and now how I'm going to plumb everything else, but for some reason this adapting step is eluding me.
First I bought this flared fitting from McMaster (LINK), the size seems close but the male SAE on the pump doesn't go deep enough to engage the threads.
I thought maybe it was a 37 degree vs 45 degree problem so I bought a Female 37° JIC fitting from here (LINK), and in that that case the male flare doesn't even fit into the threads. What am I missing here?
