Subject: [FlyRotary] aluminum hose bungs/fittings

Greetings,
 
I'm trying to decide on the fittings for my evap cores, and I haven't found much to choose from.  Straight AN bungs are pretty common, and I've also seen some NPT female bungs.  What I haven't found is any hose barb style fittings.  Ideally, I'd like to find some options for 45, or 90 degree hose barb type fittings, in about a 3/4" size, since there isn't much clearance under the outer tanks of the evap cores.  Can anyone point me to a place that sells these?  
 
BTW, I still haven't officially decided if I want to use AN hose, or just good quality "heater hose".   I'll certainly keep AN hose for oil, but I think heater hose is probably fine for water, especially with all my possible plumbing methods.   
 
Thanks,
Rusty (evap cores temporarily in place)  
 
Rusty,  while I did use AN-16 stainless steel braided hose for the radiators, I think a GOOD quality radiator hose (like those blue silicon looking type) is all you need. Perhaps replace them ever 2 - 3 years.  Pay (as you clearly are doing) attention to beads on hose connectors AND keep them out of line of sight of anything radiating large amounts of heat such as exhaust/turbocharger housings, etc.
 
The AN-16 has worked fine for me, but heavy and expensive.
