Aerator Wrench, Cache Faucet Aerator Key, Removal Wrench Tool for M 16.5 18.5 21.5 24

This replacement screwed in perfectly just like the original aerator. The flow is incredible, very fast which is what we were looking for as the original unit was extremely restricted. If you're looking to free up your flow this is the way to go. And since it's a four pack we're basically set for the next 15 years or so.

Many many thanks to this seller kaileyouxiangongsi!!! I think you may be the only place in the U.S. (maybe world) that sells this specific aerator at an excellent price: "1.5GPM Faucet Replacement Part Insert Filter, Restrictor Aerator, 18.5mm/0.72Inch" I'm so happy that you can sell these 4-packs with the installation tool for that price... don't change it PLEASE!In my experience, ALL plumbing items are usually difficult to find. The below is somewhat lengthy instructions but for a beginner to plumber it should be most helpful.I had NO CLUE what my faucet model number was when starting this quest for a replacement aerator let alone the aerator part number, I only knew that Moen was the manufacturer by reading the barely legible print on the bottom front.Side Note: For some annoying reason, faucets don't indicate the model... unless it's in some hidden spot that is only visible by removal from the sink or by some miracle or accident the parts list is still under your sink!So to find the model and part number, I went to www.moen.com --> Bathroom --> Sink then under the Filters area click Show Discontinued Products; just in case your faucet is no longer manufactured. From here you can narrow it down further by additional characteristics such as the number of holes. To determine the number of holes, you must crawl under the sink with a flashlight or better yet a smart phone to see or take a photo as I've done to show my faucet has 3 holes noted by the 3 red arrows. It helps narrow down the products a lot if you know (or think you might) the Specific Finish. In my case it is Brushed Nickel so I chose that and narrowed it down from over 1,000 three hole faucets to 185. From here, I scrolled down and found my faucet model by comparing the photos to my faucet.So after all that I discovered my faucet is called the "Eva Brushed nickel two-handle high arc bathroom faucet" Model: 6410BN". Back on the Moen website, after you click on your faucet picture, scroll down to Installation and Support (or click Support in the menu panel BELOW the faucet pic) and there you'll see Replacement Parts and you will see a list which includes the aerator part number 137401. For this faucet there is also an aerator with part number 180158 but when I searched this number on the web & Amazon it's dimensions didn't match up with my Equipment Original Manufacturer (EOM) aerator.I then searched Amazon for "moen 137401 aerator" and found really only 2 decent results. The one offered by another seller didn't give me enough certainty it would fit because it had a rubber washer on top and didn't show the dimensions. The seller kaileyouxiangongsi had all dimensions down to fractions of millimeters. So from this point, I wanted to be 99% sure it was the correct size. I pulled out a metric rule and carefully measured the height and diameter of my EOM aerator and found it matched the "Color" 4PCS-18.5mm/0.72Inch. As you can see in my side-by-side aerator pic, it looks slightly different than the EOM but it wasn't enough a difference to affect the fit.Note: The height is shown in one of the 6 picsHint: Sometimes on Amazon "color" is used for different sized products rather than actual colorSo, I added it to my cart and paid for it. I paid for a 4-pack of aerators and tool for $9.95 (with free Prime shipping & returns) from seller kaileyouxiangongsi rather than the $10.58 for the single aerator offered by the other seller. Moen was asking for $14.10 plus shipping a single aerator and tool! Both of these might fit but again the dimensions aren't shown and they really don't look the same as the EOM because of the rubber washer on the top of the aerator. This faucet's aerator does NOT have or need a rubber washer between the spigot and the aerator.The 4-pack and tool arrived quickly via UPS and I installed it with very little difficulty. Turned the water on and no leaks; faucet is now just like new!

We had an aerator that clogged after a few years even though we have water softeners. We tried multiple things to get the aerator out but could not find any documentation on how to remove and replace it. After some more extensive research, we finally decided to give this a try. The tool easily removed the aerator and the new one fit perfectly. We also realized that these aerators have SIGNIFICANTLY more flow than the ones from the factory. We don't have crazy pressure at home, but this faucet now really has great flow. We have to warn guests and remind our kids to be careful otherwise, they will wind up getting sprayed. This was a great purchase!

I have a Moen AVA two handle bathroom faucet. I'm not bragging. I paid way too much! That's another story. The original aerator was supposed to flow 1.5gpm. I tested mine and it only flowed at .75gpm. Barely enough flow to rinse a toothbrush. I was livid! I thought "What a piece of crap!" It took 40 seconds to get hot water only. Turning on both faucets at the same time did nothing to increase flow. I decided to take a chance and ordered these replacements because they were rated at 1.5gpm and were original replacement aerators for Moen faucets. I really thought they would perform about the same as the original.Wow! They are fantastic! They are labeled as 1.5gpm. I measured the flow from the cold side only and got 2.75gpm! When I turn on both hot and cold the flow actually increases! It now only takes about 10 seconds at full flow to get hot water. Better hang on to my toothbrush! They are great!

Worked like they should.

For me, the threads on this were a bit too small and would not engage so it would just fall out. It is slightly smaller than 0.85" in diameter. I ordered 2 different generic brands, this being one of them, and they both had the same issue. Returned.

I bought a set of these to change all of the aerators in my house...six bathroom sinks and one kitchen sink. The key did the job, but by the last one, it was stripped, and a lot of the teeth had broken off. I still have the other three keys that I can use, but the one I used to change out my aerators was sent on the the recycle bin. I would have to say that it met my expectations. Plastic tools like these don't hold up to a lot of use, and some of the aerators were really stuck on due to mineral deposits, and I had to really twist hard.

My aerator became plugged and while trying to clean it, it broke. I looked everywhere for one from the manufacturer but for some reason it was difficult to find? So looking on Amazon I found some that resembled it but kept looking for a slightly greater flow rate. This product said it was 1.8 GPM which was greater than the 1.2 GPM that was broken. This aerator did not look exactly like my old one (mine had what they call a coin slot for removal). This product showed clear measurements which matched mine so I bought this kit with their tool.So Long story short. It went in easily worked like a charm and my faucet now has excellent flow!For the record I have a Pfister Ladera LF-048-LR faucet. Hope this helps someone.P.S. When the box came it said the aerator was only 1.2 GPM on it, but it has a strong flow and seems greater to me.

Do what they are designed to do, great value and suspect I will never need to use the remaining 3!
