Also you ought to find a rubber cap that tightens with a hose clamp,
like a Fernco with the end closed off.

On a new clean fitting and ring, we always just used a couple layers of
duct tape. This wasn't just for the smell, it was to keep debris from
falling down there. It's not a pressurized system, so you don't need
much of a seal. It should work on an open T in the wall as well, since
liquids won't be hitting it even if there is another drain upstairs.
