Thanks for reaching out to Tundra Restaurant Supply with your question. The Winco OP-7 Overflow Pipe will fit a 1 3/4" sized drain.
This overflow tube will definitely work for your sink. We unfortunately do not have a drain stopper for your sink with the glass washer. I recommend going to a local hardware store to find something that will work.
this overflow pipe is made out of PVC plastic and a rubber top.
Exclusive offers and product updates will be arriving to your inbox soon.
