You can get an adapter Paasche to your BSP. Paasche has their own proprietary thread. I've never owned the EZ Paasche but it probably has the same thread as all other Paasche airbrushes ( I own an H and a VL)..
Badger also is proprietary ( I own an old original 100). Just list Badger or Paasche in your case, Iwata etc as the thread size, to whatever thread you need to go to. You can get adapters at Amazon. Or quick disconnects for that matter. Spray Gunner probably has them as well.
