Paul,
Need to clarify to be sure that the 1-3/8"i.d. couplings are big enough for a 20b application, or should I be using the 1-1/2" model?  Mark S.

Depends on your pump Mark. Please measure the inlet and out let inside
diameters. I have conflicting information on this measurement so far
for the three rotor pump.

This, I think, is what Butch is having made. It could be bored out slighty.

BTW this could be butt welded to 1.5 inch OD tubing.
