Rated 5 out of 5 by from Aerator Assembly After we had a bad freeze/snow a couple years ago, the aerator on the faucet needed to be replaced, the filter in it was really stopped up. I am very grateful Delta still makes these particular kitchen faucets are still made by them. Thank you, Delta for that!

What is the female ID and thread# on this part, RP81850. It is the aerator for faucet model 21716LF. I am having a hell of a time trying to find a swivel aerator to replace it with. Doesn't seem to be a standard size.
