That's it! Rubber Coupling was the word I couldn't think of. That is what I used as well. I couldn't have done it with the old set up, the new reducer is about 1 1/2 inches smaller than the stock part so it actually gave me just enough room to fit the smallest rubber coupling I could find.

FYI. My black valve was leaking slightly. I had replaced both gate valves about 7 years ago. I was not looking forward to doing it again. SO, i picked up a bottle brush at the local Albertsons. Drained the black tank, removed the sewer connection and brushed the inside of the valve thinking that maybe there was some debris on the rubber seal. After a good brushing, the leak is now gone.

Just posting this in case someone reading this thread has a similar leak. They might want to try the 3.00 brush fix before removing and replacing the valves.
