DELTA FAUCET RP61821 Addison Flange Holding Nut

It fit perfectly.

Product does NOT fit a delta kitchen faucet despite explicitly saying it does. So cheap it's not even worth my time to return, just don't waste your time buying it too.

So a water quality salesman comes to my mom's house and apparently unscrews the original aerator from the faucet to do some sort of water quality test and apparently didn't put the rubber washer back upon putting back onto the faucet by accident or on purpose. So needless to say, the water didn't flow properly and was leaking from the upper part of the aerator. It could have been an honest mistake but I'll let you be the judge. So my mom freaks out and starts tracking down this dude who committed the great offense and it's unclear whether this guy really works for the company he says he did. Another mystery. So to make a long story short I ended up ordering this part after I received some customer service help from Delta, installed it with little effort and it works just like it did before. Took about a minute to get it done. Easy peezy lemon squeezy! btw, I never found the original missing rubber washer. I looked in the sink drain, on the floor, on the counter, under the microwave... nowhere to be found. My mom's suspicions are probably accurate that this guy did it on purpose because when she spoke to someone at the company this dude supposedly works for and explained that he took something apart on the sink, they said "there should have been no reason for him to do so to conduct a water test." Dun Dun Dun (dramatic music stinger)!

Fit perfectly, exactly what I needed after several other purchases 😳

it fit very well, only problem I had you can only get it in chrome? should be able to get inn other colors.other then this it was all good.

Kitchen faucet..

Exactly as described and a perfect fit

This is simple. This aerator was an exact match to replace the one just like it on a Delta kitchen faucet.
