Is this stream type aerated or spray? The default aerator that came with my 581LF faucet is a spray pattern and I want to swap it for aerated type.

I purchased four of these faucets 581LF-BLGPM-PP from Amazon and they have been great faucets. However, the aerators they came with spray several small streams rather than one large stream. I'm hoping these aerators will be better??
Hello!
If your model 581LF-BLGPM-PP was manufactured before 1/14/2024 it will use the RP91237 aerator. If they were manufactured after this date it can only use the RP73003 aerator.
Please reach out with further questions!

How many MM is this aerator? Is it possible to swap it out with one that doesn't create so many independent streams? It sprays all over the place.

Are threads plastic or metal?
Hi Cc1123,
Thank you for your question about the Delta Faucet RP91237.
This cache aerator is a plastic material. Non-metallic products are beneficial in that they do not rust or corrode.
Please contact us directly if you have any additional questions!
