Mark,
Any sanitary fitting will only have a DWV rating(Drain, Waste and Vent) in other words it has no pressure application or schedule number, but will handle more than enough for our overflows. I have grey on hand, if you want white I can take a look and see what I can find. My wife will be in cowtown this weekend and can bring some in if need be.
Bob
