best thing to do....since you want to use your current aerator, take yours off, and take it with you....either to Lowes, HomeDepot, or any Plumbing store.....and have them show you the one that matches and fits your areator.....
they may not sell the snap nipple by itself, you may have to take a new aerator with it....
then you are set.....
a simple washer fill hose with one end cut off should fit into that opening on your twintub with ease....
