Faucet Aerator Key Removal Wrench Tool with 5 Size M16.5, 18.5, 21.5, 22.5, 24 Recessed Aerator Key Sink Aerator Wrenches for Delta Cache Faucet (5 Size)

One of these Shineyid Faucet Aerator Key Removal Wrench Tools (set of five) worked perfectly on my Delta Leland (25975) faucet that I installed about 20 years ago. We have very hard water, and the original Delta aerator was finally compromised after all these years. The aerator wrench in my instruction manual had the part number: RP46858. I could not find the exact part anywhere online, and it is no longer available from Delta.com. Glad that one of these worked, not sure which size did the job because they are not labeled.Getting the old aerator out was not easy as this was my first time removing one. At first, I used one of the slimmer wrenches and it broke apart the aerator. After realizing what I did wrong, I saw the outer ring of the aerator still in place, and one of the larger wrenches worked perfectly. Once all three parts were removed, I flushed the line. A bunch of black debris dislodged and went down the drain. I cleaned the inside of the faucet well with a bathroom disinfectant spray and flushed the faucet thoroughly a second time.I washed off the new aerator as good as possible before fitting the correct wrench onto the new aerator. If I would’ve done that right from the git go, I wouldn’t have had the problem with the old aerator. Installing the new aerator was easy, but it took a few times to get the threads on straight.

Works great

Did the trick! My wife was getting terrible water flow and couldn't get the aerator off the facet. I ordered these and read somewhere they may break easily. I soaked the aerator in a baggie of vinegar for 15 min and it twisted right off. Not sure these will last years, but they saved money on a plumber and new faucet.

Wanted to take aerators out for Moen faucets because we had lead service lines. Did not fit the Moen aerators

I have Delta faucets and I fully expected that one of these gadgets would allow me to remove the filter screen for cleaning. However, I could not get any of them to fit my bathroom faucet. Must work with some other manufacturers faucets.

This little guy helped a lot. I was able to loosen my aerator in my kitchen faucet to get max water pressure again. It started with this tool.

At first I was unsure . But these did it. I’m glad I got the 5 pack, because I would’ve ordered the wrong size, I got it right the third one I tried. Now you really have to take those few seconds to get the teeth in the right place and push up and turn at the same time, once you get the grip it’s off .. I had to go get a kitchen chair to sit on so I could rest arms on the sink and focus on what I was doing at the faucet … I’m not lending these to anyone, their mine. Lol

In case others are trying to figure out which aerator wrench fits the Riobel Parabola (and maybe others), the middle-sized wrench (it should be a 21.5mm diameter according to the listing) worked like a charm because the socket wall is thinner than the one found on the multi-colored wrench set that is offered elsewhere on this site. Hope this helps someone out there, as an inter-web search for Riobel aerator sizes produced nothing for me.
