You mean...the 4" Carlsons?
Yeah, in my perusal of this questions the issue of irregularity of schedule 40 has come up a few times, which is something I hadn't considered. If you look at the pump linked earlier in this thread you'll see it uses sort of a flat gasket instead of an O-ring, which I'd think would be better in terms of small irregularities. But I'm guessing.
That fella's 4" looks like a pretty competitive deal to me, at any rate.
