DELTA FAUCET RP51345 Lahara Aerator, One Size

The Delta RP51345 works great on my Delta Leland 2575LF-RMBPU bathroom faucets (I have 3). I spent a small fortune trying to find the right size wrench key for my Delta bathroom faucets. The Delta representative cannot help you if you do not know the exact model faucet. Finally, I went on the web and looked at every faucet with a 4 inch centercet and found my exact bathroom model. Then I looked at the printed drawing of each part of the faucet to get the aerator part number (it's listed on the specifications information for the faucet). It's sad that there is no other easy way to go about finding a wrench key to fit the aerator, but after some effort, I finally found that my aerator part was RP51345. Next I searched for this aerator part, which conveniently comes with the wrench key. It fits perfectly. It is much smaller than some of the other wrench keys I tried. One of the keys and aerators that I bought fits my Delta kitchen sink, so at least some of my money was well spent. At some point, I was so outraged with my faucet and not being able to find the correct wrench key, that I almost replaced our Delta faucets to get "regular" aerators that did not require a wrench key to remove. I'm not sure why the builder did not leave the wrench key under the sink when the house was built (only 3 years ago)... I may not have known what it was at the time, but I would have kept it in a safe place. I hope this information helps the consumer to know how to find the correct wrench key when you suddenly get lime buildup in your faucet and can't figure out how to remove the aerator.

Like several others I have a Delta Lahara faucet for my bathroom sinks. I went to Menards and Lowes who both only had the larger (red) aerator key tool. I initially thought that this was the correct size (for my Delta kitchen sink it is) but unfortunately is too large for the smaller aerator on the bathroom sinks. I was noticing very low flow in the sink despite having fresh valve stems and seals so I figured it must be the aerator and it turns out that's exactly what it was. The result of years of hard water through it. Once the original aerator was out using the blue key I was able to clean up the threads and put in the new aerator which completely fixed the problem. Make sure you get the correct size aerator for your faucet model. I just wish they sold several aerators with the one key as I need several more but only the one key.

These worked just fine for my Delta Lahara faucets.

Although there are less-expensive generic options for replacing the aerator in your Delta faucet, this is a direct replacement, from the manufacturer, so you have no worries. It fit perfectly and was simple to replace.

The included wrench is difficult to use. I luckily found my original wrenches as I have two of the delta faucets. However the filter included in this package I like better because there is not as many threads. It's funny though the original filter can be removed with a wide flat blade stubby screwdriver. Minus 1 star for the awkward universal tool.

NOT as pictured!. Key is black and multi faceted and the only thing it was useful for was banding my current Delta Aerator, and hurting my palm, as there is no grip at all. You have to turn it from an open hole into your palm. Painful and useless.

Repair of a bathroom faucet. Works great.

I will say it did work eventually but it took more effort because the supposed Delta aerator tool as shown on the listing was not the product sent to me. I chose this product because I wanted the bottom knob to ease turning the tool. The product sent to me had partial side knobs which did not allow me to push up on it to keep it attached correctly and turn it at the same time. Spent unnecessary time getting it to turn 1/2 rotation before it disconnected because I was unable to push and turn. I am not happy with this product and will purchase a true Delta tool from one of the big box stores for the same price.
