@Texgunner,
It depends on what air hose you use. I assume you have a Paasche-compatible air hose, and a Badger AB won't fit with that air hose. In that case, you need an A-151 Badger-to-Paasche-hose adapter.
Visit Chicagoairbrushsupply.com and check out various adapters for different ABs. You'll get more accurate information there than at Amazon.
