I use the brass one that come with the wax seal.
Some times the come with steel nuts.
I alwys cover them with plastic bolt caps.

Go to Chicago they don't use pvc or abs for waste pipe. They use cast iron with poured lead joints still to this day.

Is cast iron more prevalant in Chicago than else where? I would think an iron/lead joint is going to last way way longer than a PVC/ABS joint. There was nothing wrong with mine after 38 yrs. The new toilet I bought did not have high enough clearance so I had to lower the flange a little.

the thing you arnt considering beerdog is that cast iron is iron.. and as such is venerablle to oxidization, abs is chemically resistant and will not rust ever. pvc is also somewhat checmically resistant and will not rust. both plastic dwv pipes also have a smoother inner wall than cast and are less likely to clog.
