Aerator in Chrome

Delta does not provide the size specifications anywhere that I have looked so far. Their customer support also does not have any specifications as well. I have the Bellini kitchen faucet but an older version that has a maximum flow of 2.2 GPM. The newer ones have a 1.8 GPM flow so the aerator is a different size. The thread size is what is needed and this aerator is listed as having a 15/16-27 thread size. I took my old aerator to Home Depot and used their thread guide to determine the correct size and I was able to purchase a generic swivel aerator to fit the faucet. It does not look that great but it is better than no aerator at all.

Thank you for your question, Pluto! Model 19939-SS-DST uses the RP50815 aerator and wrench which is the same M21.5x1-6G thread size as aerator RP46827. Best regards, Edward

Hi Patty, Thank you for your question. We offer the RP51505 Cache aerator adaptor that will adapt the aerator threads on the model 11946-SSSD-DST to standard 55/64″-27 male threads. You can then add a swivel aerator to the adapter. Thanks, Dave

Thank you for your question, Julie! The RP46827 aerator does not come included with a wrench. The part number for the aerator removal wrench is RP52217. Best Regards, Benjamin

Hi Victor, Thank you for your inquiry! Delta does not manufacture a 1.0 GPM or any other reduced flow rate matching the RP46827 aerator. Best regards, Tanya

Hi Dave, Thank you for your question! The RP46827 is removed with an aerator wrench part number RP46858 by aligning the teeth and un-threading the aerator. Best regards, Brandis

This will depend upon which version of the faucet that you have. The older 2.2 GPM can use the RP46827 while the newest version 1.8 GPM is supposed to use the RP70718. The RP46827 has a 15/16-27 thread and is about 24 mm in diameter. The smaller aerators are about 21.4 mm.

Hi, DAW1! Thank you for your question. The Delta RP46827 Aerator Assembly has a thread size of M21.5x1-6G. Best Regards, Rosanna
