4PCS Cache Aerator M16.5, Plug-In Faucet Restrictor Replacement Parts for Kitchen and Bathroom Sink with Key Removal Wrench Tool, 1.2GPM, 16.5mm/0.65inch

Excellent product. Works well and fits my sink. The quality is average, but so far the flow is smooth. I recommend this product, but make sure you measure first.

I was able to easily replace my aerators with the key provided. They work great!

I thought the odds were slim that this would really fit and really work. But the odds paid off. I had measured roughly about 17 mm width of my faucet opening and these said 16.5mm, but they were a perfect fit. There was no leakage, no errant side spray, no problems whatsoever. They send a very strong stream of aerated water just as promised. Such a great improvement on the old aerators that were partially clogged.

I didn’t expect much with this product and got what I paid for. The removal tools are cheap and none of the aerators fit a Delta bathroom faucet.

standout features is the inclusion of the two key removal wrench tools, These made installation and replacement incredibly easy. These aerators are well-made and fit perfectly into both my kitchen and bathroom faucets.

Just what we needed.

I couldn’t find a brand replacement in any of the descriptions for all the options available. Nothing said Delta (I think that is what I have). Thankfully I have a micrometer and I could confirm that my filter was 16.5 mm after I took it out.So, attached pictures show the filter sitting on a dime, aligned to the bottom lip. You can see sliver of the top of the dime. Shown for reference only. Hope it helps.BTW, major improvement in the water flow. Happy.

Good product

I like this Aerator kit because it works with my kitchen sink or washroom faucet and it comes with 2 faucet removal keys making the entire fixture process easier just unscrew the old one and insert these new ones and they just work easy peezy especially if your sinks or faucets shouls i say get clogged up with sediment or hard water depending on the area you live in so overall i recommend this kit because it's great priced and comes with 8 piece/Aerators more than enough for some time. So if your looking for a great deal then try this out Cheers.
