Are you sure you were not using 1 1/2" pipe? There is no way a 2" coupling would fit into a 2" hub, much less a "donut".
: : Without being there it is impossible to tell if things are just not fitting together properly. But it is possible that they won't since the lead hub was never designed to have the "donut" installed in it, so it could have the wrong dimensions.

: : : : Matt,
: : : : Have you "tried" it yet?
: : : : My experience with them, is that the 2" ABS expands the rubber seal when inserted to full depth.
: : : : I round the end of the pipe with a knife and use soft soap for lube.

: : :
: : : The seal kind of fits when the pipe is installed, but it is still loose. If I push the pipe and seal in all the way (pushing the seal flange into the hub) it fills the gap, but it really doesn't hold the pipe as securley as I would like.

: I was finally able to get the donut seal to work by placing a 2" coupler on the end of the pipe. The larger OD made the seal work properly. Thanks for the help and the great site.
