I'm sure there is, but I'm PVC ignorant.
I just went to the hardware store and got the stuff that said 1" (because it was cheaper than 1.25", 1.5" or 2").
I test fit it all to make sure it was compatible, and off I went.
I believe the stuff I used is schedule 40, but again as long as you get all compatible parts it doesn't matter what you use.
