Check out Horizon Irrigation's web site:

They carry the SDR series.  This is important in the 4 inch IPS (which is
actually 4.5 inch OD) because the thinner wall SDR has an ID slightly over
4 inches while the schedule 40 has an ID slightly under 4 inches.
If you want to slide 4 inch OD irrigation pipe inside 4 inch IPS PVC
pipe, it has to be the SDR type.  (Note, this only applies to the
4 inch size.  Schedule 40 is fine for 2 and 3 inch PVC).

Another supplier for exotic pipe is Ferguson:
