Paul,   A new development in radiator design is soon to be offered by C
& R.  It is an inlet/outlet  bung that has incorporates an O-ring for
sealing.  With this radiator  you can mix and match fittings, AN, Pipe,
regular hose neck, as  you see fit.  They just screw in.  C & R can now
offer AN up to 1.25" and they can supply built hoses.

Hi Jerry;........These are known as AND Bosses or Bungs, that can be easily
purchased, or you can make them yourself if you purchase the contour cutting
tools (not that expensive) from fitting suppliers such as Parker-Haniffin,
available from -4 (1/4" tube) and up.
With these tools (they look like short counter bores) you can port blocks,
plates etc.
They are used on Drill Presses, Millers, Lathes, Hand Drills etc.

IMO, it's the only way to go since they provide a much better and safer
connection since pipe threads induce wedging forces which usually leads to
cracking or loose connections, especially in our application where we
experience vibration and extreme temperature changes.
